<P>PROBLEM TO BE SOLVED: To provide a combustion device which controls a fuel supply pressure to a burner with the discharge pressure of a fan for combustion air supply as the signal pressure, and is capable of easily and accurately stipulating the positional relation or the like of a signal pressure detection part and a resistance board part for increasing the signal pressure to desired specifications. <P>SOLUTION: The combustion device C includes a fan 2 for supplying combustion air through an air flow path 17 to a burner B, a signal pressure detection part 40 for detecting the discharge pressure of the fan 2 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, and further includes an auxiliary member 4 which is configured separately from the fan 2 and an air flow path forming member 1 and is attached to the fan 2 or the forming member 1. The auxiliary member 4 is provided with the signal pressure detection part 40, and the 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. <P>COPYRIGHT: (C)2012,JPO&INPIT |
