For the CFB boiler, this paper proposed the optimal control strategy to reduce
the coal consumption. By combining the RTO technique and DMC with zone
control, the proposed method not only ensures the normal process conditions but
also achieve the coal-saving. This proposed method is verified by a case study of
a 150 t/h circulating fluidized bed boiler of the power plant in Sichuan.
