Combustion air is supplied being divided into inner and outer cylinders of a main burner body, and liquid fuel is injected and burnt by a liquid fuel injection nozzle provided in the inner cylinder, wherein a tip end injection hole of the nozzle faces outside of the nozzle through a fore end opening of the inner cylinder. An annular flame piloting baffle plate for the inner cylinder is provided in front of the injection hole of the tip end opening of the inner cylinder, a swirler is provided inside of a tip end portion of the outer cylinder, and an annular flame piloting baffle plate is provided at a tip end opening portion of a cylindrical space formed between the outer and inner cylinders. Due to the foregoing construction, flames of the burner for burning liquid fuel are stabilized and an amount of generated NOx gas is reduced.
