摘　　要：采用正交试验设计法设置试验因素和水平,寻求不同负荷下的锅炉最优运行方式。考虑了辅机电耗的影响,提出了锅炉净效率概念。以锅炉净效率为主要优化目标,综合考虑再热汽温、烟温偏差等因素,通过试验得到锅炉不同负荷下主要控制参数和控制曲线,提高了锅炉运行的经济性和安全性。The orthogonal experiment was used to determine factors of the test for boiler combustion optimization under various loads. With consideration of power consumption of the auxiliary equipment, the concept of net boiler efficiency is proposed. According to the reheat steam temperature and the flue gas temperature differential, the main control parameters and the control curves of the boiler under various loads were obtained through the test with the net boiler efficiency taken as the main optimization target. The economy and safety of the boiler are improved greatly.
