Abstract
A combustion apparatus mainly consists of burners, a fuel supply channel having branched channels, an air feeder for supplying air to the burners, and a pressure regulator and has a combustion space. The branched channels allow fuel gas supplied to the burners to pass therethrough and are provided with shutoff valves. The pressure regulator includes a signal-pressure inlet and a secondary-pressure inlet. A signal pressure introduced through the signal-pressure inlet is detected at a downstream of the air feeder and a secondary pressure introduced through the secondary-pressure inlet is detected at a vicinity of a boundary of the branched channels in the fuel supply channel. Fuel gas discharged from the pressure regulator is regulated so as to satisfy a predetermined relationship between the signal pressure introduced through the signal-pressure inlet and the secondary pressure introduced through the secondary-pressure inlet.
