摘　　要：结合锅炉运行工况中热效率与空气系数的特定关系曲线,利用最优控制理论,引入步进搜索自寻优程序方案确立最佳风燃比,寻求不同负荷状态下的最佳风燃比,实现锅炉经济稳定燃烧,达到节约能源、环保运行的目的。By using the optimal control theory and the scheme of stepping search for the self-optimizing control, an optimal air-fuel ratio is determined through relation curves between thermal efficiency and air coefficient of boiler under various operating conditions at different loads, so as to achieve a complete burning of fuel and optimal thermal efficiency of boiler.
