The numerical simulation and experimental research of Low-NOx burner retrofitting on a 420 T/h utility boiler

摘要

The thermal test was carried out on a 420 T/h utility boiler of Xiaoshan power plant,the boiler can reach satisfactory performance and the thermal efficiency reaches 91.07％; Then a numerical simulation of the pulverized coal combustion was carried out on the basis of the test,by means of thermal aero dynamical field analysis and temperature field analysis,as well as the research for the pollutant,the numerical simulation results are in good agreement with the experiment,which provide good guidance for the Low-NOx burner transformation of the future large-scale station.
