| Abstract: | In newly built large-scale coal-fired power plants,the boilers are all designed and installed with low NOx combustion systems,by which the in-furnace combustion process is reasonably organized to achieve low NOx formation and emission.Computation and analysis of a 1 000 MW supercritical boiler equipped with advanced low NOx combustion system in a power plant were carried out by computational fluid dynamics(CFD) simulation approach.Through analysis on the obtained in-furnace fields of temperature and CO,O2 a... |
