A combustion apparatus includes combustion means generating combustion exhaust by combustion of fuel, heat exchange means exchanging heat of the combustion exhaust, and exhaust dilution unit supplying dilution air after the heat exchange by the heat exchange means and diluting the combustion exhaust after the heat exchange, and controls a temperature of the combustion exhaust after the heat exchange below a predetermined temperature by dilution by air supply.

Combustion apparatus, method for combustion control, board, combustion control system and water heater

A water heater includes combustion means (burner) that combusts fuel and generates exhaust; heat exchange means (primary heat exchanger and secondary heat exchanger) that exchanges heat of the exhaust for supplied water; bypassing means (bypass pipe) that makes the supplied water flow to an outlet of the heat exchange means; exchanged heat temperature detection means (exchanged heat temperature sensor) that detects temperature of the supplied water after heat exchange; flow rate adjustment means (bypass valve) that adjusts a volume of the supplied water flowing into the bypassing means and the heat exchange means; and a control unit that controls the flow rate adjustment means so as to make a predetermined volume of the supplied water or over flow to the heat exchange means.
