Numerical Simulation of Flow in the Vaporizing Burner

The numerical simulation of the gas flow in a small-sized vaporizing burner was completed based on STAR-CD, and the flow of the burner's main region was analyzed. According to the computation and analysis, some conclusions are drawn as follows: the primary air entering the glow plug chamber can promote mixture of the vaporizing oil on oil net; the secondary air produced in the tangential inlet bent pipe can lead to strong swril thus promoting the gas complete mixed and combustion; the primary and secondary necking in the burner can make the eddy sustained and arouse local back-flow to stabilize flame; split holes can reduce the flowing dead zone and decrease the noise in combustion. The analysis of the results illustrates completely the design and the reliability of the burner when it works.
