Abstract
Disclosed is a structure of a burner which can be fueled with gas fuel or oil fuel. The main features includes: a specially designed swirl generator; an annular hollow gas gun; an oil gun received in the gas gun where the gas jets of the gas gun and the oil jets of the oil gun have an predetermined angle with respect to the centerline. Under designed operating conditions, a swirling air flow can be generated with a low pressure drop and low turbulences, which is beneficial to flame stability, reducing flame temperature, and delaying the mixing of air and fuel, thus inhibiting the formation of NO.sub.x. Staging air and flue gas recirculation are available for further reduction of nitrogen oxides.
