Wood-gasifying boilers

The ATTACK wood gasifying boiler is intended for economical and ecological heating of the family houses, small plants, work stations and similar objects. Wood is the main fuel for the ATTACK boilers. By full utilization of the feeding chamber there is possibility of the continual burning for 8- 12 hours.

Description

TvarovkyThe boiler is constructed for combustion of wood, on principle of wood gasification by usage of the suction fan, which exhausts the flue gas from the boiler and makes underspressure in the boiler hopper. The underpressure in the hopper ensures, that in the moment of opening of the feeding door, the clean air is sucked from the enviroment to avoid of the small elements elusion from the boiler hopper into the boiler room. The boiler room with this kind of boiler is significantly less dusty.

The boiler consits of two chambers divided by nozzle. The boiler fuel hopper is in the bottom part equipped with the heatproof adapting piece with longitudinal opening for transfer of the gas and flue gas.



The refractory ashtray is placed in the burning-out space under the nozzle in the boiler rear part. The tubular exchanger with the heat-up flap above is in the rear part of the boiler. There is also the exhaust connection for chimney. It is possible to turn this connection horizontally or vertically, following requirements at installation. In the upper part of the front wall, there is the feeding door and in the bottom part is the ashtray door. To enable comfortable manipulation, it is necessary to isolate the boiler door from the combustion section of the boiler properly.

At the full operation – the insulation ensures, that the door surface will be just a little bit warmer than the surrounding environment. For this purpose, the compressed isolation filling of high quality is used for the ATTACK® boilers. This isolation
is typical with the low heat transfer coefficient, low specific weight and sufficient tightness in comparison with standard isolation materials. Moreover, in the boiler door it is protected by the plate to prevent mechanical injury in case of uncareful treating.

Pull rod of the heat – up flap is placed in the front covering. The boiler body is from external side thermally isolated with mineral wool, fitted under the coverings of external coating. The control panel for electromechanical regulation is placed in the upper part of the boiler. Boiler covering is powder treated. The channel for the primary and the secondary air inlet is in the front part of the boiler, together with the regulation flap, where it is warmer to the high temperature. The boiler is equipped with the heat-up flap. This flap opens automatically, when the feeding door is opened and shuts automatically, when the feeding door is closed.

The boiler is equipped with all functional and security elements. The boiler is equipped with the safety thermostat, that turns the ventilator electrically off in the state of emergency when the temperature exceeds 95°C.
