Numerical Study on the Stereo-staged Combustion Properties of a 600MWe Tangentially Fired Boiler

摘要：

Numerical study of the combustion process and NO emission of a 600 MWe tangentially fired boiler with stereo- staged combustion system were performed by Fluent 6.2 CFD software.The stereo-staged combustion technology is consist of horizontal bias combustion (HBC) burners,separated over fire air (SOFA),horizontal offset secondary air and pulverized coal reburning arrangement.The temperature field and the distribution of combustion species concentration in the furnace were gained as well as the aerodynamic field.The simulation results shows that stereo-staged combustion system can keep good combustion stability and the NOx emission of the boiler reduces significantly when the HBC burners and horizontal offset secondary air are adopted.
