Bi-fuel boiler for solid biomasses, such as wood logs and pellet
Burner fan placed downstream the combustion chamber.
Misaligned combustion with downward reversed flame, with triple modulation: - modulation through inverter on boiler temperature: to maintain the correct stoichiometric ratio - modulation on smokes temperature: to prolong the autonomy, guaranteeing the safety of the combustion - modulation on optic reading: to regulate the speed of the fuel feeding screw, so optimizing the combustion
Low polluting emissions and very high efficiency: 89% with wood and 92% with pellet, that guarantees a rapid amortization
Incandescent combustion chamber in special thermal stainless steel AISI 430, 8 mm thick,highly heat-stable and resistant to the high temperatures and to potential chemical aggressions
Grate in thermal steel INOX AISI 310, 15 mm thick
Lateral primary air chanels, with a thickness of 4 mm
Vertical smoke pipes with mobile turbolators, automatically shaked by levers with timed activation, in order to increase the efficiency of the boiler (practical ashes removal from the front)
Self cleaning pellet burner, in stainless steel AISI 304, placed behind the boiler
Modulating fan with control by inverter, positioned in the suction side for optimization of the combustion
Two independent loading feeding screw of safety reason
Safety heat exchanger
Pellet reservoir, optional: that can be placed on the RH or LH side of the boiler and automatically feeds the burner
Wide wood storage, with front by-pass, for wood logs, to guarantee long intervals of operation
