Influence of combustion instabilities on the heater appliance with atmospheric gas burner and their elimination by cross flow of air

This paper presents results of experimental investigation on elimination of combustion oscillations caused by new low pollution burner which was integrated in a gas heater. The method is known as a passive method, based on introducing the air in the combustion chamber. Because the efficacy of the method is highly dependent of the way the air is injected some methods were investigated and compared. The paper also presents effects on pollution characteristics during its operation in the unstable regime.
