Abstract

Abstract: In order to study the influence of nozzle and ejector structural parameters on the primary air coefficient, the nozzle and ejector of a burner are modeled by two-dimensional parameterization, and the numerical simulation technology is used for simulation calculation. By analyzing the calculation results, the influence of each parameter on the primary air coefficient is summarized. In addition, using these rules to optimize the multi-parameter comprehensive structure of innovative five-ring fire gas stove, the primary air coefficient is effectively improved and the emission concentration of flue gas is reduced.

Key words: Numerical simulation, Ejector, Primary air coefficient, A parameterized
