置に関する。DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention is a method for mixing combustion air sent from a supply air blower with gas fuel, and then blowing out the mixed gas from a burner head. The present invention relates to a forced air combustion type combustion device that performs combustion.

ず、燃焼状態が不均一となる欠点があった。(b) Conventional technology This type of forced-air gas combustion equipment can obtain sufficient combustion air using the air supply blower, so it can achieve a large amount of combustion with a compact shape, especially for outdoor air supply and exhaust gas combustion equipment. It is highly useful as a combustion heating source for hot-air heaters, and the gas combustion device as described above was developed in 1986-14.
It is known from Publication No. 3437. By the way, in this conventional configuration, the passage of the mixed gas inside the burner body becomes narrower as it approaches the flame hole, so the jetting speed of the mixed gas from the flame hole is fast, and the combustion device is in a cold state. When ignited, a lifting phenomenon accompanied by intense combustion noise occurred, making it difficult to ignite. In addition, since the mixing promotion plate with many through holes is installed close to the flame holes, it is not possible to send the mixed gas uniformly to each flame hole, resulting in uneven combustion conditions. Ta.

The burner body includes a nozzle and a blower that supplies combustion air to an air passage around the burner body, and the burner body has a stepped part in the middle to form a small-diameter first mixing chamber on the base side, and a tip. A second mixing chamber with a large diameter is formed on the side of the burner body, and the first mixing chamber and the second mixing chamber are communicated through a mixing promotion plate provided with a large number of through holes. The peripheral wall facing the mixing chamber is provided with an introduction tube for supplying gas fuel and primary air into the first mixing chamber in a spiral manner.
