Ecological wood gasification boilers

Generator Dokogen boilers are characterized with a special chamber which is on both sides laid with special ceramic shaped parts, with primary air inlets in the lower section and with ceramic nozzle and in lower chamber with spherical ceramic parts. Rear flue duct is equipped with a tubular heat exchanger.

Gasification of wood (inverse burning) with subsequent combustion of wood gas in ceramic combustion chamber ensures optimum burning of all combustible components. The air supply and combustion process are controlled with exhaust fan. This allows quick ignition and good combustion of the boiler since the firing up. The flame temperature is 1000 - 1250 ° C.

Inverse burning (gasification) and ceramic combustion chamber enable practically complete combustion with a minimum of harmful exhalations. The boilers meet limits of European regulations for environmental friendly product and belong to 5th class of boiler standard ČSN EN 303-5. Meet the most demanding requirements of the EU - ECODESIGN 2015/1189.

Advantages of wood gasification boilers ATMOS
