Control method of fluidized bed gasifier system

The invention discloses a control method of a fluidized bed gasifier system. The method comprises the following steps: control on feed system: the control system receives the material level condition in a rotary storage bin detected by a material level indicator installed on the rotary storage bin; when the raw material in the rotary storage bin is lower than the set material level, the control system sequentially controls a bin top feed screw to start, a feed lifter to start and a bin top feed valve of the rotary storage bin to open, thereby starting the automatic feed state; and when the raw material in the rotary storage bin is higher than the set material level, the control system sequentially controls the bin top feed valve to close, the feed lifter to stop and the bin top feed screw to stop, thereby stopping the feed state. The control method of the fluidized bed gasifier system can implement automatic control on the feed system, and has the advantages of high control accuracy and high automatic control
