摘要
Abstract
NOx. emissions from a 600 MW supercritical boiler with swirl burner were investigated by performing a serial of tests such as changing O2 concentration, air-distribution of different level burners, secondary air ratio, secondary and tertiary air swirl strength, air-distribution of the burners in same level and boiler load. The test results show that for the bituminous coal fired boiler with swirl burner, the O2 concentration, over fire air (OFA) ratio, boiler load and air-distribution mode of the burners in same level are the main factors affecting NOx emissions. In order to reduce NOx emissions and keep higher boiler efficiency, the following principles about combustion adjustment should be obeyed: (1) the O2 concentration should be kept in the premise of ensuring safe operalion of boiler as lower as possible;{2) large proportion of OFA should be adopted; (3) boiler load should not be loo low; (4) two-peak air distribution mode should be taken among the same level burners.关键词
