本考案は強制給排気式燃焼器に関し、特に給気
不良による不完全燃焼防止の安全装置に関する。[Detailed Description of the Invention] The present invention relates to a forced air supply/exhaust type combustor, and particularly to a safety device for preventing incomplete combustion due to insufficient air supply.

つた。 Conventionally, in semi-enclosed forced air combustors that are surrounded by an exterior with an open air supply and exhaust port, incomplete combustion occurs even if the air supply port is clogged with dirt, dust, etc. and there is insufficient air supply. There was a risk that combustion would continue under such conditions and harmful gases would be emitted, and soot would be generated and adhere to the heat exchanger, significantly reducing efficiency.

The figure shows a schematic configuration of an embodiment of the present invention, in which 1 is a forced air supply and exhaust type combustor according to the present invention, 2 is a heat exchanger, 3 is a burner, and 4 is the burner 3.
This is a solenoid valve installed during fuel supply. 5 is a differential pressure detection mechanism that detects the differential pressure inside and outside the combustor 1;
5a is a diaphragm, 5b is the diaphragm 5a
The pressing rod 5c that engages with is a switch portion. The switch portion 5c is electrically connected in series with the electromagnetic valve 4 and has a normally closed contact. 6 is a fan, 7 is a large number of air supply ports opened on the outer surface of the combustor 1, and 8 is an exhaust port. Note that the present invention may be a forced exhaust type combustor in which a fan 6 is provided in the exhaust section of the combustor 1.

全燃焼を継続することはない。 The present invention has such a configuration, and its operation will be explained next. During operation of the combustor 1, if the air supply port 7 is clogged with dirt or dust and air cannot be supplied sufficiently, the intake action of the fan 6 will cause the combustor 1 to
The internal pressure becomes significantly negative compared to the outside of the combustor 1, and the diaphragm 5a of the differential pressure detection mechanism 5 deforms and pushes the pressure rod 5b, opening the normally closed contact of the switch part 5c and turning on the solenoid valve 4. The solenoid valve 4 cuts off the fuel supply path to the burner 3. Therefore, the burner 3 stops combustion, and incomplete combustion due to insufficient air supply does not continue.

危険を除去すると共に熱交換器にすす等が付着し
て効率を低下させることを防止する効果がある。 In this way, the present invention is equipped with a differential pressure detection mechanism that detects the differential pressure between the inside and outside of the device in a forced air supply and exhaust type combustor, and shuts off the fuel supply path to the burner when the inside of the device becomes significantly negative pressure relative to the outside of the device. This eliminates the risk of incomplete combustion by stopping combustion if the air supply port becomes clogged with dirt or dust, resulting in insufficient air supply, and also prevents soot from adhering to the heat exchanger, reducing efficiency. It has the effect of preventing deterioration.
