COMBUSTION DEVICE

PROBLEM TO BE SOLVED: To provide a combustion device capable of obtaining stable combustion flame without generating vaporizing pulsation by continuously supplying liquid fuel to an evaporating section even in weak combustion.SOLUTION: This combustion device including a burner for burning a premixed gas prepared by mixing a combustion gas and primary air, includes a fuel diffusing member for diffusing the liquid fuel from an oil feed pipe, and the fuel diffusing member is constituted of a metallic plate and mesh and kept into contact with the evaporating section at one or more points. By applying this configuration, the liquid fuel is continuously supplied to the evaporating section even in weak combustion, the generation of vaporizing pulsation is not found, the combustion flame is stabilized, and a wide combustion width can be obtained.
