<p><P>PROBLEM TO BE SOLVED: To provide a technology capable of reducing noise generated in a combustion device burning a hydrocarbon fuel, as much as possible. <P>SOLUTION: This combustion device includes a fan 2 for blowing out the combustion air in a first direction D1, a diffusion path 11 for guiding and diffusing the air flow blown by the fan 2 in a second direction D2 perpendicular to the first direction D1, a connection path 12 for guiding the air flow supplied through the diffusion path 11 in the first direction D1 at the end in the second direction D2, of the diffusion path 11, and a burner 3 for guiding the air flow from the connection path 12 through an inlet 10 in the direction opposite to the second direction D2 and mixing it with the hydrocarbon fuel to burn the same. The connection path 12 is formed as a straight path having the rectangular cross-section, and the inlet 10 is formed at a downstream side with respect to a reattachment point to a wall surface defining the connection pathway 12 of a separated flow formed at a bent section 14 connected to the connection path 12 from the diffusion path 11. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
