PURPOSE:To perform a complete combustion and to improve the combustion efficiency of the burner by completely separating a nozzle zone, a combustion air flow zone, a fuel evaporating zone, a mixing zone, a combustion zone, and a high temperature combustion gas circulating zone. CONSTITUTION:After ignition, a hot combustion gas is sucked into a burner cone 6 by a circulating operation and an atomized fuel is instantaneously evaporated by the heat of the fuel gas. The evaporated fuel flows along the inner surface of the cone 6 and forms an oxygen starvation layer (a) together with the circulating gas and further flows into a throttle portion 20 formed between the outlet portion of the cone 6 and the smoothening plate 8. In the throttle portion, the fuel gas is promoted to mix with combustion air which has flowed through the central portion of the cone 6. The yellow flame in the inner part of the burner cone 6 sucks up the combustion gas and at the same time moves to the after flow portion of the smoothening plate 8 wherein the mixed gas is ignited and forms a flue flames. As a result, a complete combustion can be performed and the combustion efficiency can be improved.
