摘要：In this paper, models for NOx emission prediction and denitration costs are built with support vector machine. The effects of the factors such as SCR inlet NOx content, unit load, oxygen content of exhaust gas, ammonia injection rate, air distribution condition, and coal type on NOx reduction are discussed. The denitration costs under different working conditions are calculated. The ammonia injection rate is optimized with genetic algorithm. It can be shown that the actual ammonia injection rate is 1%-3.5% lower than the optimal value.
