【Abstract】 A procedure has been developed for predicting the flow pattern, temperature distribution and heat flux pattern within the end fired cylindrical furnace(precombustion chamber) used in large capacity boilers to take pulverized coal fire in order to save the fuel oil. The turbulent two-equation model and the Monte Carlo technique are used in predicting. It is considered that the mathematical simulation method can be applied to prediction of the characteristics of practical cylindrical combustion furnaces.更多还原
