Many raw materials choice change control manner and the device of the fluid bed gasification reactor in gasification equipping

摘要

P To provide a method and a device for controlling the selective change over of various raw materials of a fluidized layer gasification furnace in gasification equipment, capable of adjusting the residence time of the fluidized medium staying in the gasification furnace in accordance with the kinds of the raw materials thrown into the gasification furnace, capable of setting its gasification rate that is a carbon conversion rate and as an objective value even for the raw materials having different gasification characteristics and performing a stable operation. PSOLUTION: The residence time of the fluidized medium of the gasification furnace 2 can be controlled by introducing the fluidized medium to any of a plurality of fluidized medium-throwing-in ports 20a, 20b, 20c connected to the gasification furnace 2 in accordance with the kinds of selected raw materials, introducing the raw material to the raw material-throwing-in ports 22a, 22b, 22c joined with prescribed positions in the longitudinal direction of the gasification furnace 2 corresponding to the above and taking out the fluidized medium from a fluidized medium-taking-out port 24 joined with the gasification furnace 2 to introduce it to a combustion furnace 5.
