2 How It Works
IGNIS uses wood-logs - by its construction it could be called a 'boiler with wood gasication eect'.
Following image depicts the combustion principle of this boiler.
1. Combustion chamber 2. 'Catalyst' with tubulators 3. Heat exchanger of the safety valve line 4. Tubu-
lators (heat exchangers inside the upper zone) 5. Secondary ue opening 6. Flue box (a part of the heating
chamber around the ue) 7. Boiler water 7.1 Boiler water around the ue chamber 8. Secondary air inlet 9.

As IGNIS is similar to wood gasication boilers, the main properties of the wood gasication boilers
will be outlined rst. A wood gasication boiler, thanks to its special geometry, and thanks to use of the
3
fan, brings the woodlogs in the state of 'gasication' - the process where light weighted hydrocarbons. The
ame has a specyphic blue colour and the eciency of such solid fuel boiler is 10-15% greater than that of
the conventional ones. Another interesting property of wood gasication boilers is that the woodlogs are
placed in the upper chamber and the ame is inverse - going upside down contrary to conventional boilers.
Wood gasication combustion requires a constant and stationary boiler operation. It is thus necessary
to have an additional heat tank to accept the excess heat made by boiler. It is also necessary to perfectly
adjust temperatures between the heat tank, ow and return line of the boiler to prevent condensation. All
in one, wood gasication allows maximum comfort with wood-logs as a fuel, but with certain investment
to be made into additional equipment.
The IGNIS boiler lls the room between the less pricey conventional boilers, which demand rell
of wood more often and maximum comfort yet more pricey wood gasication boilers (with heat tank).
Because of its technical construction IGNIS allows the wood gasication eect (in amoutn much less
than 'real' wood gasication boilers) but only using the natural draught of the boiler, without a fan and
without a necessary heat tank. What is still necessary is the protection against condensation (mixed
valve, by pass of the boiler). IGNIS does not have an inverse ame.
As it does not posses the automatic regulation via fan, optimum combustion is achieved by setting the
primary and secondary air. Primary air is controlled by the draught regulator (to be ordered separately)
and the secondary air is to be set manually.
In which way the wood gasication eect is achieved? Wood gasication process takes place in the
upper zone of the boiler - within the so-called 'reproof catalyst'. This is a special cylindric part of the
heating chamber. On its upper side there are special heat exchangers (tubulators). Below the catalyst
with presence of secondary air, at very high temperatures, solid particles are accelerated to certain level
until they combust completely. Short-chain hydrocarbons are released. Flue gases are passing through
turbulators - in contact with increased surface of the tubulators ue gases are additionally cooled down -
exit ue gas temperature is thus lower compared with conventional boilers. The eciency is higher. The
concentration of dust, particles and COX/NOX is lower.
IGNIS has a secondary ap inside the chamber. The role of this is to shorten the passage of ue
gases and increase the draught in the boiler when necessary (during ignition for instance). when th ere
is stable this secondary ap should be closed. IGNIS also has a so-called 'ue-box'. Water content of the
boiler is maximized occupying a part of the ue chamber.
3 Recommendations for boiler shipment and storage
3.1 Delivery form
The boiler comes in three parts, boiler chamber, pellet storage and the boiler housing packed separately.
Chamber is wrapped with plastic sheet, and upper door containing reproof glass should have a small
styrofoam protection sheet. The whole set is transported on wood pallet.
The boiler must always stand in its vertical position. The rotation of the boiler during the shipment or
installation represents a serious risk and can lead to damaging the boiler. It is forbidden to stack boilers
vertically one onto other.
The boiler can be stored only in closed rooms with no atmospheric inuence. The humidity in the storing
room also must not exceed the critical value of 80%, so as not to create any condensate. The temperature
of the storing room must be in the range of +/- 40 C.
