Summary:The invention discloses a combustion control method and device for a circulating fluidized bed boiler. The method comprises the following steps: selecting an AGC instruction or a CCS load instructionby an AGC input/ cut-off button during AGC put-in, and taking the sum of the load instruction and a primary frequency modulation load instruction as a set value of a power regulator; taking a target main steam pressure/pressure set value as a set value of steam turbine pressure regulator and boiler main control through rate limitation; entering a CCS mode if the boiler main control input is automatic and steam turbine main control input is automatic; entering an BF mode if boiler main control input is automatic and steam turbine main control input is not automatic; entering a TF mode if steamturbine main control input is automatic; entering a machine-furnace manual mode if steam turbine main control input is not automatic; outputting a fuel instruction by boiler main control, and taking the sum of the fuel instruc
