A fan is rotatably disposed in a combustion chamber (26) and driven by a motor (3). The fan has fan blades each having a leading edge and a trailing edge. An angle of the leading edge relative to a rotational plane of the fan is approximately equal to an angle of the trailing edge relative to the rotational plane, whereby high degree of turbulence is generated from the position near the leading edge.",
