<P>PROBLEM TO BE SOLVED: To provide a combustion device capable of increasing a fuel supply pressure to a burner by increasing a signal pressure used in a pressure adjusting valve without turning a rotation speed of a fan for combustion air supply so high. <P>SOLUTION: The combustion device C includes a signal pressure detection part 40 for detecting the discharge pressure of a fan 2 for combustion air supply as the signal pressure Ps and a pressure adjusting valve V for controlling the fuel supply pressure to the burner B to a pressure corresponding to the signal pressure Ps, and further includes a resistance board part 41 which is positioned at the air flow direction downstream part of the signal pressure detection part 40 and is for increasing the signal pressure Ps. The resistance board part 41 is arranged so that it is shifted to a part of the peripheral edge part 24 of a discharge port 20 from the center position of the discharge port 20 in the facing direction view of the discharge port 20 of the fan 2, only an area around a part of the peripheral edge part is closed, and the other area is turned open. <P>COPYRIGHT: (C)2012,JPO&INPIT |
