Drying of wooden material

Warming

Emission of gas contents

Gas combustion

Gas burn-down,

Reduction of CO

Each of these phases requires different conditions. However, there is only one possibility of regulation by usual devices - closing

of the air inlet. Thereby, there is lack of air for one process and too much air for another one and also the temperature is

sometimes sufiicient and sometimes not. Because of unperfect combustion, many combustible contents wastely flow out

through the chimney or react with other products of combustion and make tar.

BOILER FUNCTION

By loading of new fuel - at the temperature of 200°C - it comes to drying of wood. Near to the nozzle, at the temperature of 200-

700°C and limited air inlet, the wood is scanned, the wood gas is emitted and the solid elements are produced. Emitted gas flows

into the combustion chamber, burns and emits heat under the sufficient air inlet.

Wood gasification is traditional technology that improves efficiency of wood combustion that improves efficiency of wood

combustion. Combustion means rapid oxidation of material, when warmth is released.

Operation of pyrolising boiler can be divided into 3 processes - warming and drying of wooden material in the hopper, it comes to

releasing of water steams, gas contents and to combustion of solid content (charcoal).

PYROLYSIS OF WOOD

Charcoal is burned on the grate, under the sufficient air inlet. It reacts with

air and emits combustible CO, which is immendiately burned.

Incombustible waste goes through the nozzle to the ashtray. Advantage of

this approach is, that every combustion phase has ideal conditions - in the

regulated amount of primary and secondary air, as well as in optimum

differentiation of temperatures for individual phases of combustion.

Thanks to better usage of warmth in the wooden material, there is lower

fuel consumption and wide scale of the output regulation at keeping high

combustion efficiency.
