PROBLEM TO BE SOLVED: To provide a combustion device free from degradation of heat exchanging efficiency of a heat exchanger even in a case of partial combustion, and capable of suppressing corrosion of an internal wall surface by suppressing generation of drainage including oxide. SOLUTION: This combustion device 51 includes a flow channel forming member 56 including a mixing section 57 and a plurality of branched flow channels 62, a combustion space 61, an air blower 53, and a pressure regulator 55. The pressure regulator 55 regulates a pressure of a gas supplied with a primary pressure, to a secondary pressure according to a signal pressure of the air blower 53, and a signal pressure of the pressure regulator 55 is detected from the air blower 53 or a downstream side of the air blower 53. Opening/closing valves 63 are disposed in the branched flow channels 62, and a combustion area can be increased or decreased by opening and closing the opening/closing valves 63. Further, the flow channel forming member has a double structure, and a part of the distributed air can flow to an air flow channel for cooling. COPYRIGHT: (C)2010,JPO&INPIT
