Abstract

PURPOSE: To provide a simple apparatus capable of controlling combustion of a forced intake and exhaust type combustor, by providing a pressure switch for detecting presence of air supply and a pressure switch for detecting the minimum combustion rate, and keeping the minimum combustion rate when the latter pressure switch is in operation.
CONSTITUTION: In a forced intake and exhaust type combusting apparatus of this invention, fuel gas is supplied from a gas nozzle 12 while ejecting air from an air nozzle 2, and after mixing them together, the mixture of fuel gas and air is ignited and combusted by a burner 6. Here, the above apparatus is provided with a first pressure switch 20 having pressure chambers 30, 31 communi- cated respectively to ports 32 and 34 and a second pressure switch 21 having pressure chambers 28, 29 communicated respectively to ports 33 and 35. In case that the combustion rate is relatively high, that is, air-flow rate is high, contacts 18, 37 are closed by the function of the above two pressure switches 20, 21 for keeping a thermoelectric safety valve 9 open. On the other hand, in case that the speed of a fan 7 is lowered, a circuit for holding the minimum combustion rate is set into operation with only the contact 37 of the pressure switch 21 being opened.
