BOILER WITH SEALED COMBUSTION CHAMBER AND CYLINDRIC HEAT EXCHANGER

摘要

Air collector for a steam-tight boiler using a blown air burner. The air box (11) has a flat oblong shape and receives the combustible air through an orifice (20) concentric to the discharged tube (16) of burnt gases; the air leaves the box through an orifice (14) towards the air inlet chamber (12) arranged vertically along the exchanger. Application to steam-tight boilers with cylindrical exchanger.
