摘　　要：在一维沉降炉上对某电厂燃用的几种褐煤及其混煤燃烧时的NOx 排放特性进行了研究 ,着重考察了炉膛温度、过量空气系数、二次风风温、一二次风配比、给粉量以及掺混比对NOx 排放的影响。A study on the property of NO x emission during combustion of several coal sorts and their mixtures in a power plant has been carried out in one-dimension subsiding furnace. The infuence of some factors, such as the furnace temperature, the coefficient of excess air, the temperature of primary air, the match ratio of primary air and secondary air, the quantity of supplying coal powder, and the mixing ratio of different coal sorts etc., upon NO x emission has been emphatically investigated, providing theoritical basis for high efficiency and clean combustion in large-scale boilers.
