Numerical Simulation of Waste Heat Boiler for Copper Flash Smelting

Abstract

Based on the results of a thermal equilibrium, temperature and velocity distributions of the waste heat boiler were simulated. Results show that the gas flow doesn’t rush to the top intensely when the first baffle-board is set in the front of the radiation chamber. Flue gas is so strongly disturbed by the second baffle-board that its residence time is increased. These two baffle-boards enhance the heat transfer intensity in the radiation chamber. The relative error of simulation results to experimental is less than 10%.
