HG boiler used two-stage combustion process - gasification of fuel and subsequent pyrolysis that is combustion of formed gases. Wood fuel is used as a primary fuel. Boiler heat exchanger is made of high quality attested boiler plate with 6-8 mm thickness, in form of two chambers located above each other - connecting function of combustion chamber and ash-pan. Grate is located between the chamber allowing ideal gasification of wood and easy removal of ash. Wood gasification process allows using energy accumulated in fuel and meet the rigorous emission parameters. Combustion process is adjusted using innovative controller with touch display. HG boiler is equipped with exhaust fan that protects it against backflow of smoke to the boiler room. Boiler can be assembled in the closed system.
