Units of measurement for wood fuel

The units of measurement commonly used in forestry and the timber industry for wood fuel are solid measures of timber (smt) and stacked cubic metres (stcm). The solid measure of timber (smt) describes 1 m3 of solid timber mass in the form of assorted round timbers.

The stacked cubic metre (stcm) is a measure for stacked or tipped wood, measuring a total volume of 1 m3, including air gaps. On average, one solid measure of timber equals 1.4 stacked cubic metres.

Calorific and emission values

Timber is a renewable fuel. During combustion, on average approx.

4.0 kWh/kg units of energy are released. The table shows the net calorific value of various types of timber with a water content of 20 %.

1 litre of fuel oil can be replaced by 3 kg of timber, considering the usual efficiencies. A stacked cubic metre (stcm) of beech corresponds to the energy of approx. 200 litres of fuel oil or 200 m3 of natural gas. Therefore burning wood contributes to the preservation of the finite reserves of oil and gas. Timber has a generally neutral CO2 balance, as the CO2 created during

combustion is immediately reabsorbed into the photosynthesis cycle and therefore contributes to the formation of new biomass. Another environmental aspect is the fact that timber contains hardly any sulphur, therefore almost no sulphur dioxide is created during combustion.

Influence of moisture on the net calorific value

The water content of timber substantially influences its net calorific value. The more water timber contains, the lower its net calorific value, since the water evaporates during combustion and consumes energy in the process. Two measures are used to specify the water content.

■ Water content The water content of timber is its water mass as a percentage of the total timber mass.

■ Timber moisture level The timber moisture level (hereafter referred to as moisture or moisture level) is the water mass as a percentage of the total timber mass excluding water.

The graph shows the relationship between the water content and the moisture level, as well as the dependency of the net calorific value.

0 10 20 30 40 50 Water content in %

0 25 50 100 Moisture level in %

Calorific value kWh/kg

Freshly cut timber has a moisture level of 100 %. During storage over one summer, this moisture level reduces to approx. 40 %. During storage over several years, this moisture level reduces to approx. 25 %.

The diagram shows the dependency of the net calorific value on the water content, using spruce as an example. With a water content of 20 % (moisture level 25 %), the net calorific value is 4.0 kWh/kg. The net calorific value of timber stored over several years is approx. twice that of freshly cut timber.

Storage

Not only is the combustion of moist wood uneconomical, it also leads to low combustion temperatures and high emissions plus tar deposits inside the chimney. Information on storing firewood

■ Split round logs from a diameter of 10 cm upwards. Enlarging the surface area enables the wood gases to be expelled more quickly and simply. The drying process is also accelerated during storage.

■ Stack the logs in a ventilated and preferably sunny spot underneath a rain canopy.

■ Stack the logs with generous air gaps to enable the flowing air to carry off the dissipating moisture.

■ A hollow should be created underneath the wood pile (e.g. in the form of support timbers) to allow moist air to escape downwards.

■ Never store freshly cut wood in a cellar, as air and sunshine are required for drying. However, dried wood can be stored in a well ventilated cellar.

1.2 Minimum wood fuel requirements

Wood remnants, coarse woodchips and compressed shavings can be used in the Pyromat Eco. The Pyromat Eco is ideal for the combustion of logs. The wood should have an edge length between 45 and 50 cm or up to 100 cm (depending on the boiler type: boilers for 50 cm logs or 100 cm logs). The rated wood boiler heating output will only be achieved with dry wood with maximum 20 % water content (air-dried wood). Wood of poorer quality and higher moisture content also reduces the rated heating output and the length of combustion.

When using softwood (e.g. spruce), note that the energy per volume unit is lower than with hardwood (e.g. beech). Softwood is therefore suitable for "initial heat-up" - however, its use shortens the intervals between recharging considerably and increases the volume to be used (up to 44 %). Observe the requirements specified in the next chapter relating to non-combustible substances and their limits for warranty period claims. Deviations are only possible through written, systemspecific manufacturer declarations.

Substances

When procuring wood for combustion in a Pyromat Eco, ensure that foreign objects (e.g. stones, metal parts, pieces of brick, plastics etc.) are avoided. These would change the composition of the fuel and therefore the critical parameters of the combustion process.

The values must not exceed or fall below the following limits (per kg of dry fuel) for the non-combustible content (ash at an analysis temperature of 815 °C):

Limit Comparison with natural wood from forests

Chlorine Cl mg/kg max. 300 10 Sulphur S mg/kg max. 1000 120 Total Cl, S mg/kg max. 1000 130 Ash content total g/kg max. 15.0 5.0 Alkali oxides in the ash (K2O and Na2O) g/kg max. 1.0 0.35

SB start of ash sintering °C min. 1000 approx. 1200

Exceeding the above limits will shorten the service life of the combustion chamber and wood boiler. This also means that maintenance work is increased and service intervals are reduced.

The proportion of dust-like and fine-grained materials should also be minimised (in accordance with ÖNORM M 7133).

Origin, treatment and storage

Depending on the origin, wood can be natural wood (e.g. forest wood and waste from sawmills), residual wood from wood processing plants or waste wood (building rubble, furniture). The wood must be obtained and cut to the desired size, and foreign objects deal with appropriately. In addition to the requirement to adhere to ÖNorm M 7133, a max. proportion of 5 % outliers in the fuel should be observed.

The length of the outliers must not exceed 16 cm (with a cross-section of max. 5 cm²). The surface of the fuels should be roughened where possible (e.g. through shredder, etc.). When using briquettes, ensure compression is matched to charging. The maximum diameter is 60 mm.

Size of the woodchips

The Pyromat Eco is also suitable for the combustion of coarse woodchips. To prevent increased maintenance work, appropriate coarse woodchips in accordance with ÖNorm M 7133 should be used.

Further information

Ash and cleaning

Natural wood without bark has a percentage of ash less than 0.5 % of the supplied fuel mass. All information regarding cleaning work is based on natural wood with attached bark and an ash percentage of

0.8 %. The cleaning and maintenance work for other wood fuels should be adapted according to the quantity, the specific weight and the ash characteristics.

Changing fuels

Frequent and intensive changes in fuel quality, e.g. bulk density, water content, dust proportion and ash content, can require a manual adjustment of the combustion system parameters.

Non-wood biomass fuels

Non-wood fuels made from biomass such as needles, leaves, cereals, straw, husks, fruit stones, etc. are unsuitable as fuels for fault-free operation, and are therefore not permitted.

In some cases, the fuel properties (elemental composition, ash sintering point, etc.) differ considerably from those of wood. Combustion of such fuels in a Pyromat Eco can lead to an impairment of the combustion characteristics and increased stress on the fireclay lining and the heat exchanger surfaces. Warranty claims can therefore only be asserted when using approved fuels.

The Pyromat ECO was developed specifically for the combustion of logs and represents state of the art combustion technology. The Pyromat ECO log boiler has already proven itself thousands of times. Charging from the top offers easy handling, control via the Lambda probe guarantees low emissions, and the integral heat management ensures maximum convenience.

Clean and efficient combustion

The microprocessor control captures all details relevant for the operation and regulates the amount of heat required and provided. As a result, the boiler system is monitored permanently in all operating phases, from heat-up and operation under load right through to burnout, and is held within its optimum operating range by its motorised air dampers. This guarantees clean and efficient combustion.

Large hopper

The Pyromat ECO offers the greatest operating convenience when heating with logs thanks to its large charging chute. Log boilers in the rated heating output range 40 to 75 kW can operate with logs of 0.5 m length; in the range 85 to 170 kW, the hopper width increases to 1080 mm, ensuring convenient charging even with logs of 1 m length.

With oil burner connection

The Pyromat ECO is also approved as an oil boiler compliant with EN standard; the necessary connections are already in place. Fitting an oil burner may, for example, help to bridge holiday times when manual charging with logs is not feasible. The Pyromat ECO is particularly suitable for the combustion of logs, wood briquettes and wood remnants, either loose or in pieces. The Pyromat ECO boiler system has been tested in accordance with the latest quality criteria to EN 303-5 "Heating boilers for solid fuels", and can be brought into circulation with CE designation (directive 98/38/EC etc.) and VKF approval.

Circulation pump curves and pressure drop on the heating water side

The residual pump head results from the differential between the selected pump curve and the pressure drop curve of the respective heating circuit distributor or further components (pipe assembly, distributor etc.). The following pump graphs show the pressure drop curves of the different Divicon heating circuit distributors. Maximum flow rate for Divicon:

■

with R ¾ = 1.0 m3/h

■

with R 1 = 1.5 m3/h

■

with R 1¼ = 2.5 m3/h

Example:

Flow rate ´ = 0.665 m3/h

Selected:

■ Divicon with mixer R ¾

■ Wilo Yonos Para 25/6 circulation pump, variable differential pressure operating mode and set to maximum delivery head

■

Pump rate 0.7 m 3/h

Head of the relevant pump curve: 48 kPa Divicon pressure drop: 3.5 kPa Residual head: 48 kPa – 3.5 kPa = 44.5 kPa.

Note

For further components (pipe assembly, distributor, etc.) determine the pressure drop and deduct it from the residual head.

Differential pressure-dependent heating circuit pumps

According to the [German] Energy Saving Ordinance (EnEV), circulation pumps in central heating systems must be sized in accordance with current technical rules. Ecodesign Directive 2009/125/EC requires high efficiency circulation pumps to be used throughout Europe from 1 January 2013, if the pumps are not installed in the heat source.

Design information

The use of differential pressure-dependent heating circuit pumps requires heating circuits with variable pump rates. These include, for example, single and twin line heating systems with thermostatic valves and underfloor heating systems with thermostatic or zone valves.

Note

If an oil burner is used on the boiler, dimension a is increased if the burner is fitted on the left, or dimension c if the burner is fitted on the right.

Siting

The following points must be observed for siting:

■ Avoid air contamination by halogenated hydrocarbons (e.g. as contained in sprays, paints, solvents and cleaning agents)

■ Avoid very dusty conditions

■ Avoid high levels of humidity

■ Prevent frost and ensure good ventilation

7.2 Connection on the flue gas side

The boiler is equipped with a flue gas fan, therefore the combustion equipment does not require a draught. The chimney must be designed in the same way as for combustion equipment with a pressure-jet oil or gas burner without draught requirement (flue gas temperature at rated load 160 - 200 °C). To prevent the risk of soot contamination, provision must be made for an insulated chimney.

The route from the flue gas fan to the chimney should be as short as possible. 90° bends should be avoided wherever possible. Flue pipes more than 1 m long should be insulated. The chimney should be connected rising at an angle of 30 - 45°. The flue pipe, including inlet to the chimney, must be gas-tight.

Safety equipment according to DIN EN 12828

DIN EN 12828 requirements include having the following safety equipment installed:

Sealed system:

■ Sealed expansion vessel, type-tested.

■ A safety valve (max. set pressure 3.0 bar, type-tested to DIN 3440) at the highest point of the boiler or on a pipe connected to this point. It must not be possible to shut off the connection line between the boiler and the safety valve. No pumps, fittings or constrictions may be present in this line. The discharge pipe must be designed in such a way that no pressure increase is possible. Any expelled heating water must be drained off safely. The outlet point of the discharge pipe must be arranged in such a way that any water expelled from the safety valve can be drained off safely and visibly. Nominal diameter of the valve, the connection line and the discharge pipe to DIN 4751 Part 2.

■ Thermally activated safety valve, R ¾, individually tested, opening temperature 95 - 100 °C (safety heat exchanger integrated into the boiler)

■ High limit safety cut-out

■ Cold water supply DN15 R ½, fixed metal pipe, min. 2.5 bar, max.

3.5 bar, drain line R ¾

■ Air separator (recommendation: absorption dust extractor)

■ Thermometer and pressure gauge.

■ Low water indicator not required.

7.4 Frost protection

An antifreeze additive suitable for heating systems can be added to the fill water. The antifreeze manufacturer must verify its suitability, since otherwise damage to gaskets and diaphragms can occur as well as noise during heating operation. Köb accepts no liability for any resulting damage or consequential losses.

7.5 Operating the boiler with an oil burner

■ The oil burner can be fitted to the left or right of the boiler for emergency operation. The burner trolley is required for this (see page 20).

■ Before being used, the burner must be pushed into the boiler's combustion chamber

■ The boiler's combustion chamber must be thoroughly cleaned before and after use of the burner

■ The oil burner must be selected according to its max. rated heating output. See specifications in the following table

Oil supply

Single line system

Size the oil line in accordance with the following table. For this, observe the oil line requirements to DIN 4755-2 [or local regulations]. The height differential H (see fig.) between the oil burner pump and the foot valve in the tank set below the oil burner pump must not exceed 4 m. Greater height differentials lead to noisy operation and pump wear. An oil feed pump with intermediate tank is required in the immediate vicinity of the boiler, if the suction head or maximum pipe run for tanks set below the boiler is greater than that shown in the following table. Site the intermediate tank so that the oil supply can occur using the integral oil burner pump. The oil feed pump must be regulated independently of the boiler, i.e. no signal from the boiler must be used for this purpose. The oil line should have a vacuum pressure of no more than

0.40 bar.

Anti-lift valve

■ Fuel oil tank systems where the highest possible fuel oil level inside the tank is (or could become) higher than the lowest point of the fuel oil suction line require an anti-lift valve.

■ Where a tank is set above (level of foot valve or floating inlet is higher than the oil pump), do not install mechanical anti-lift valves. Instead, use an electric solenoid valve.

■ When installing an anti-lift valve ensure that the negative pressure on the inlet side of the oil burner pump will not exceed -0.4 bar in the most unfavourable case.

Prevention of damage due to corrosion on the water side

The service life of any boiler as well as that of the complete heating system is influenced by the quality of the water. The cost of a water treatment facility is certainly less than the cost of repairing damage to the heating system. Adherence to the following requirements is a warranty condition. The manufacturer's warranty excludes damage due to corrosion and scaling. The following is a summary of essential water qualities. A chemical water treatment can be ordered from Viessmann for filling.

Prevention of damage through corrosion on the water side

The corrosion resistance of ferrous materials on the heating water side of heating systems and boilers depends on the absence of oxygen in the heating water. The oxygen, which enters the water in the heating system when it is filled for the first time or topped up, reacts with system materials without causing any damage. The characteristic blackening of the water after some time in use indicates that free oxygen is no longer present.

The technical rules and in particular VDI Directive 2035-2 therefore recommend that heating systems are designed and operated so that a constant ingress of oxygen into the heating water is prevented.

Opportunities for oxygen ingress during operation:

■ Through open expansion vessels receiving a flow

■ Through negative pressure in the system

■ Through gas-permeable components

Sealed unvented systems, e.g. with a diaphragm expansion vessel, offer good protection against the ingress of airborne oxygen into the system, if correctly sized and operating at the correct pressure. At all points in the heating system, including on the intake side of the pump, the pressure must be higher than the pressure of the surrounding atmosphere in all operating states. The pre-charge pressure of the diaphragm expansion vessel should be checked at least during the annual service.

PYROMAT ECO

5822 546 GB

Page 48

The use of permeable components, e.g. permeable plastic pipes in underfloor heating systems, should be avoided. Provide system separation if such components are nevertheless used. This must separate the water flowing through the plastic pipes from other heating circuits, e.g. from the heat source, by the provision of a heat exchanger made of corrosion-resistant material. No further anti-corrosion measures are required for sealed unvented hot water heating systems subject to the above points being observed. However, take additional precautions where there is a risk of oxygen ingress, for example by adding oxygen binder sodium sulphite (5 - 10 mg/litre into the excess). The pH value of the heating water should be between 9.0 and 10.5.

Different conditions apply to systems that contain aluminium components. Where chemicals are used as part of the corrosion protection, we recommend that the manufacturer of the chemicals issues a certificate of suitability of the additives with regard to the boiler materials and the materials of the other heating system components. We recommend you refer questions about water treatment to Viessmann industrial services or an appropriate specialist. Further details can be found in VDI Directive 2035-2 and EN 14868.

8.1 Pyromat Eco with two heating circuits with mixer, heating water buffer cylinder and DHW heating with DHW cylinder

ID: 4605384_1304_04

Applications

Heating system with log boiler, with one or several heating circuits with 3-way mixer, heating water buffer cylinder plus DHW heating.

Main components

■ Pyromat Eco

■ Ecotronic boiler control unit

■ Return temperature raising facility

■ Heating water buffer cylinder

■ DHW cylinder

■ Buffer cylinder control valve

Function description

In order to achieve the required set temperatures in heating circuits

tP/zP

or for DHW heating uP, the Pyromat Eco 1 runs through the

following operating phases:

■ Heat up

■ Load operation

■ Residual heat utilisation

■ Drawing [heat] from the buffer cylinder These are shown on the control unit display.

Heat up

Boiler 1 starts after charging and lighting the fuel. Initially, the air dampers are zeroed.

Load operation

If the flue gas temperature exceeds 120 °C or the residual oxygen content is less than 15 % (for 2 minutes), the air dampers enter their controlled mode. For this, the air dampers are constantly regulated to the respective set value via the value of the actual residual oxygen content. The actual flue gas temperature will be prevented from exceeding its max. value by the flue gas fan and the adjustment of the primary air dampers.

Residual heat utilisation

The residual heat utilisation phase begins if the flue gas temperature falls below 100 °C. Buffer cylinder control valve rT remains closed and boiler control valve 4 remains fully open for as long as the boiler flow temperature is higher than the set system temperature.

Drawing [heat] from the buffer cylinder

If the boiler flow temperature falls below the set system temperature, the heat for heating circuits tP/zP or for DHW heating uP is drawn from heating water buffer cylinders rP/rQ. For this purpose, boiler control valve 4 is completely closed and buffer cylinder control valve

fully opened.

Return temperature raising facility

The Pyromat Eco 1 requires a minimum return temperature. When boiler circuit pump 3 starts, boiler control valve 4 opens the path from the central heating return to the Pyromat Eco 1 in line with the increasing return temperature and closes the path from the boiler flow to the boiler return (bypass). As soon as boiler control valve 4 is fully open, buffer cylinder control valve rT takes over return temperature raising.

Charging the heating water buffer cylinder

During the combustion phase, heating circuits tP/zP/uP are supplied with heat first of all by boiler circuit pump 3. As soon as the consumers enter controlled mode, the boiler heat not required for heating purposes is routed via buffer cylinder control valve rT into the heating water buffer cylinder, maintaining a precise temperature stratification. Following burnout, the residual boiler heat is utilised by the buffer charging management, before the consumers are supplied by heating water buffer cylinders rP/rQ.

Heating by the Pyromat Eco

The boiler heat is routed to the heating distributor by boiler circuit pump

if the boiler water temperature of the Pyromat Eco 1 exceeds 65 ºC. At this point, 3-way mixers tR/zR regulate the flow temperature in accordance with the specified heating curve in weather-compensated mode.

Heating by the heating water buffer cylinder (heat drawn from the buffer)

fully opened. The heat required to supply the heating circuits is drawn from the heating water buffer cylinders using heating circuit pumps tE/zE. The flow temperatures are also regulated in weathercompensated mode via 3-way mixers tR/zR.

DHW heating

When the temperature at cylinder temperature sensor uW falls below the set value, circulation pump for cylinder heating uE starts and DHW cylinder qP will be heated. Circulation pump for cylinder heating

Charging the heating water buffer cylinder

During the combustion phase, heating circuits tP/zP/uP are supplied with heat first of all by boiler circuit pump 3. As soon as the consumers enter controlled mode, the heat not required for heating purposes is routed via buffer cylinder control valve rT into the heating water buffer cylinder, maintaining a precise temperature stratification. Following burnout, the residual boiler heat is utilised by the buffer charging management, before the consumers are supplied by heating water buffer cylinders rP/rQ.

Heating by the Pyromat Eco

The heat is routed to the heating distributor by boiler circuit pump

Heating by the heating water buffer cylinder (heat drawn from the buffer)

Heating by the oil/gas boiler

Boiler control unit 2 of Pyromat Eco 1 enables oil/gas boiler eP via contactor relay eI if the actual boiler water and heating water buffer cylinder temperatures are below the set system temperature. At the same time, buffer cylinder control valve rT closes and the two-way valve in the boiler return of oil/gas boiler eP opens. Oil/gas boiler

now takes over heat supply for the heating distributor in weather-compensated mode. The flow temperatures are also regulated in weathercompensated mode via 3-way mixers tR/zR by boiler control unit

of Pyromat 1.

DHW heating

When the temperature at DHW cylinder sensor uW falls below the value selected, circulation pump for cylinder heating uE starts and DHW cylinder qP is heated. Circulation pump for cylinder heating

continues running until the DHW temperature at cylinder temperature sensor uW has reached its set value. To optimise cylinder heating, regulating valve uR takes the flow rate higher or lower, depending on the temperature spread between cylinder temperature sensor uW and return temperature sensor uT. With DHW heating by oil/gas boiler eP, the boiler water temperature of oil/gas boiler eP is raised for DHW heating through a demand from extension kit uQ via external EA1 extension eW and contactor relay

Note

Pyromat Eco and oil/gas boilers must be connected to separate chimney stacks. Match the heating curve of the oil/gas boiler to the heating curve of the heating circuit with the highest flow temperature. Depending on the system scope and layout, we recommend that these are offset upwards in parallel.
