PROBLEM TO BE SOLVED: To provide a liquid fuel combustion device capable of reducing NOx by lowering a temperature of flame formed from a burner port of a combustion disc into a combustion chamber. SOLUTION: In a burner 10 wherein atomizing combustion is performed by igniting liquid fuel scattered from a space S between a vaporization cylinder 31 and a scattering ring 32 into the combustion chamber 11, evaporating the liquid fuel by heating the vaporization cylinder 31 by combustion heat in the atomizing combustion, and jetting the evaporated fuel from the burner port 29 formed on the combustion disc 16, a clearance C is formed at a top wall 31A side of the evaporation cylinder, and the cooling air is directed to a high-temperature area of flame through a through hole 35B of a fuel diffuser 35 positioned in the evaporation cylinder and the clearance C.
