6 TECHNICAL DESCRIPTION

The boiler is designed to burn wood on principle of the wood gasification by using the exhaust
fan that sucks the flue gas from the boiler. In automatic pellet mode when is inserted the pellet
burner in the upper door, the boiler heat on wood pellets, which burn in the combustion cham-
ber of the burner. Transport of pellets ensure the external pellet feeder from the external tank. It
is not allowed to operate with the boiler on both fuels at the same time.
The boiler body is welded from the steel plates of 3 – 6 mm thickness. In the feeding chamber
there is a fireproof nozzle with longitudinal opening for the flue gas and gas passage. In the
burning chamber there is a fireproof ashtray.
In the rear part of the boiler body is the tubular exchanger with the flue gas collector and the
heat up flap in the upper part.
In the front parts there is a feeding door and at the bottom there is the ashtray door.
Between the doors there are the primary and secondary air inlets placed under the boiler cover-
ing. In the left covering at the same level as the middle of the feeding door there is a pull rod of
the heat up flap that is controlled by the feeding door and there is also the lever for exchanger
cleaning.
The boiler body is insulated by a mineral wool, inserted under the external covering. The control
panel for electromechanical regulation is placed in the upper part of the boiler (operation with
wood).
On the right side to the heat exchanger is mounted the holder of console for pantograph system
for holding the burner. On the console are pins which attached two arms of the pantograph,
with burner door and the burner. ATTACK PELLET BURNER Automatic 8 – 30 kW or 15 – 50 kW
works on basis of the fuel feeding by the principle of falling, when the pellets fall by from the
pellet feeder through the inlet hose and the inlet tube on the grate, where they are burned. The
burner has an electrical ignition that automatically lights the pellets fallen on the grate. It is
equipped with a self–cleaning mechanism of the grate.
ATTACK PELLET BURNER Automatic 8 – 30 kW consists of combustion chamber from 3 mm heat–
resistant stainless steel, air chamber with fan and units for self cleaning mechanism of the grate.
Base of ATTACK PELLET BURNER Automatic 15 – 50 kW combustion chamber consists of com-
bustion chamber from 4 mm heat–resistant stainless steel, air chamber, grate for pellet burning,
control units and self cleaning of the grate.
