Mixing chamber for burner with fan

摘要

Air from the fan and combustion gas, controlled by a solenoid valve, are fed into the chamber to which the burner for the mixture is connected. At the opposite end from the burner, air and gas are fed tangentially and in the same flow direction into the tubular chamber (1, 2), so as to generate a current with a spiral component. The air-feed pipe into the chamber can taper towards the latter, and there can be a nozzle (10) immediately before the gas inlet into the chamber. The air and gas inlets can be diametrally opposite each other.
