LIQUID FUEL COMBUSTION DEVICE

PROBLEM TO BE SOLVED: To provide a liquid fuel combustion device capable of reducing NOx by easily radiating heat of a high-temperature area by 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, the number or opening area of burner ports per a unit area of the combustion disc at an opening part side of the combustion chamber is determined to be more than that at a bottom part side, thus the high-temperature area of flame is shifted to the opening part side of the combustion chamber 11, and the heat can be easily radiated.
