PURPOSE:To provide a liquid fuel combustion device having a simple configuration and capable of reducing ejector noise in an inexpensive manner. CONSTITUTION:A heat exchanger 29 receiving a thermal transmittance from a gasifier device 1 and heating primary air is arranged around an injection nozzle 6. There is provided means for feeding a part of hot air discharged from an upper part of a combustion cylinder 21 while reheating it. With such an arrangement, gasification gas injected from the injection nozzle 6 and the heat primary air can be mixed to each other, the temperature difference at the time of mixing can be reduced and the noise value of the ejector can be reduced by about 4dB. |
