Abstract:In order to increase the smelting intensity of the U-shaped waste circuit boards incineration smelting furnace and prevent the mass of pollutants, the paper built the simulation model according to the smelting process, optimized the operational parameters of the U-shaped waste circuit boards incineration smelting furnace, designed a 4 factors 4 levels L₁₆(4₄) orthogonal plan, the simulation study is carried out to investigate the effects of the operational parameters(i.e. the preheating temperature, the air oxygen concentration, the excess air ratio and the waste circuit boards particle size) on gas oxygen concentration、C burning rate、CO burning rate and pollutant emissions. The simulation results show that the best features of the U-shaped waste circuit boards incineration smelting furnace are high temperature、low air oxygen concentration、small excess air ratio and small waste circuit boards particle size.
