1.1 Principles of pellet combustion for generating heat
What are wood pellets?
Wood pellets are made from 100% natural wood remnants. This raw material is waste matter created by the wood industry in large volumes
through planing or sawing. Wood remnants are compressed under high pressure and formed into pellets, i.e. pressed into a cylindrical shape.
The raw material is stored and transported in completely dry conditions. The system user should also ensure completely dry storage conditions.
Optimum and effective combustion can only be ensured under these conditions.
Fuel requirements
For combustion in the PYROT, use pellets with a diameter of 6 mm, a
length from 5 to 30 mm (20 % up to 45 mm) with a maximum residual
moisture content of 10 %.
The wood pellets used for combustion in the PYROT must correspond
to the requirements of DINplus or ÖNORM M 7135.

Quality characteristics
High quality pellets:
■ Smooth shiny surface
■ Uniform length
■ Low proportion of dust
■ Sink in water
Low quality pellets:
■ Cracked rough surface
■ Severely varying length
■ High proportion of dust
■ Float in water
Forms of delivery
In their loose form, pellets are transported by silo tanker and pumped
into the storage room via a hose system.
Careful handling of pellets enables a low proportion of dust, troublefree boiler charging and a constant wood boiler output.
1.2 Principles of woodchip combustion for generating heat
What are woodchips?
Woodchips are made from 100 % natural wood from forests and plantations. This raw material comes in the form of trunks or branches. The
wood is then processed with high speed cutting tools in accordance with ÖNORM M 7133.
The raw material is stored and transported in completely dry conditions. The system user should also ensure completely dry storage conditions.
Optimum and effective combustion can only be ensured under these conditions.
Fuel requirements
For combustion in the PYROT, use woodchips with a maximum coarse
percentage of 20 %, a maximum cross-section of 5 cm² and a maximum length of 12 cm (5 % with max. 16 cm).
Bulk density S (kg/m³, water content W (%), size G (mm) as per ÖNORM M 7133
S 200 W20 G30/50 Soft natural woodchips from forests
S 250 W20 to W35 G30/50 Soft natural woodchips from forests
S 300 W20 to W35 G30/50 Soft/hard natural woodchips from forests
S 300 W35 to W50 G30/50 Soft natural woodchips from forests
S 350 W20 to W35 G30/50 Hard natural woodchips from forests
Quality characteristics
High quality woodchips:
■ As per ÖNORM M 7133
■ Size G30 or G50
■ Max. 5 % outliers
■ Smooth surfaces
Low quality woodchips:
■ Frayed surface
■ More than 5 % outliers
■ Coarse percentage higher than 20 %
■ Greater than G30 or G50

1.3 Minimum wood fuel requirements
Content
When procuring wood for combustion, it is important to ensure that
foreign matter (e.g. stones, metal parts, brick fragments, plastics, etc.)
is avoided. This changes 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
A consequence of exceeding the above limits is a shortened 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-grain materials should also be
minimised (in accordance with ÖNORM M 7133).
Non-wood biomass fuels
Non-wood biomass fuels, such as needles, leaves, grain, straw, husks,
fruit kernels, etc., are generally unsuitable as a fuel for trouble-free
operation and are therefore not permissible.
In some cases, the fuel properties (essential composition, ash sintering point, etc.) differ considerably from those of wood. Combustion in
a Pyrot may lead to impairment of the combustion characteristics and
to greater stress on the fireclay lining and the heat exchanger surfaces.
Warranty claims can therefore only be asserted when using permissible fuels.

Ash removal
With its patented rotation combustion, the Pyrot wood boiler represents state of the art wood combustion. A supply screw conveyor continuously guides the wood fuel onto a moving grate on which the fuel
combustion takes place. Continuous gasification takes place under air
starvation. A rotary fan is used to mix rising combustion gases with the
secondary air displaced in a rotary motion. This ensures thorough
mixing with the combustion gases.
Clean and efficient combustion
The proven combustion technology in the Pyrot achieves similar emissions values to those of a modern gas combustion system and keeps
the release of CO, NOx and dust particles to a minimum, subject to
fuel type. The combination of combustion technology and digital modulating output control enables efficiency levels of up to 92 %.
Mobile containerised heating centre
Pyrot wood boilers are available as containerised complete solutions
for uses where there are no boiler houses available or where the onsite building costs have to be reduced to a minimum. This complete
solution incorporates the pre-assembled wood boiler inside a special
container with all ancillary devices. In addition to finished container
solutions, individual versions can be specially matched to your
needs.

3.5 Mastercontrol for two-boiler systems
The Mastercontrol optimises the entire heat generation of two biomass
boilers (PYROT dual system) incl. control of an oil, gas or electric boiler
as a redundancy and/or as a peak load boiler.
Information on the Mastercontrol
Function:
■ Heat management:
Optimum division of the required output between the two biomass
boilers with the main load on the lead boiler and the remaining load
on the lag boiler via a default output value. The default output is
calculated in accordance with QM wood heating stations in line with
the required set temperature in the common low loss header. Automatic switchover of the two boilers between the lead boiler and the
lag boiler is possible. This ensures an even boiler load over a long
operating time (e.g. weekly changeover).
■ Charging:
If fuel for the two biomass boilers is taken from a common fuel store,
charging is controlled up to fuel distribution by the Mastercontrol.
■ Operating data archiving:
Relevant operating data of the past 31 days is stored in a ring buffer
and can easily be displayed in graph form on the Mastercontrol
touch-screen.
Operation:
Operation is carried out via a 10“ touch-screen integrated in the control
panel.
