At present, for the most part of new construction Coal-fired units desulfurization system has canceled the GGH system in our country, using the wet chimney emissions, but when the Power plant operationed it always apper the phenomenon of “gypsum rain”. In this paper, using the method of extraction part of hot secondary air to heating clean flue gas, and use fluent for three-dimensional numerical simulation with pipeline has been transformed and before it hasn’t transformed, using the κ-ε model and SIMPLE algorithm for calculating. Through the comparison of simulation results and test results, the results indicated that using the methods of hot secondary air to heating clean flue gas to reduce gesso rain is feasible and reasonable.
