Effect of dispersing combustion method on reducing noise of commercial active air inlet quick burner

The commercial active air inlet quick burner has extremely large combustion power ca. 6300 W, but it also generates huge combustion noise ca. 100 dBA. Literatures mentioned that the noise contribution of quick burner involved pipe flow and combustion explosion, and the latter is the main noise source. A new dispersing combustion assembly to reduce the noise of active air inlet quick burner was developed, which was designed by following the linear equation for addition of combustion energy and the logarithmic equation for the addition of noise. This assembly is composed of a porous flame plate, a diversion device and a burner core. As the porous flame plate covers on and the diversion device introduces into the quick burner, a chamber is formed that makes the gas and fresh air mix more uniformly, and then the mixed gas will be separated through the holes of the porous flame plate and yielded numerous fasciola combustions, that can not only reduce the combustion noise up to 25-30 dBA, but also increase the combustion efficiency up to 123%. Moreover, the other advantage of this assembly is that it could be simply equipped with the commercial quick burner and unnecessary to modify the original structure of commercial quick burner which makes the cost down. By implementing this assembly, the kitchen labors' hearing could be efficiently protected as well as reducing the potential of noise induced hearing loss.
