Numerical Simulation Aerodynamic Field And Temperature Field With Swirl Coal Combustion Burner Of WangQu Power Plant

As the most abundant fossil energy,coal occupies an absolute dominant position in the structure of energy production in China.With the rapid growth of China's economy,the domestic thermal power industry has developed rapidly.Due to the good combustion stability,the wide adaptability to coal and low pollution,swirl burners have got more attention in recent years.In addition,the computer software is used to simulate the combustion status and pollutant generation process of power station,which has become an effective research means.Because the combustion process is a complicated physical and chemical process in large thermal power plant,the accurate description of the process needs to be improved.This paper makes a numerical simulation of a Bi-register swirl coal combustion burner,observe and analyze the velocity field and temperature field of burner regions by changing the angle of inner second air blade and the damper positions of inner second air,disclosures the movement law of pulverized coal-air flow.Besides,makes a numerical simulation for the situation of blended coal combustion and provide guidance to the operation of power plants.
