CFB boiler fire coal coupling solid waste treatment method

The invention discloses a CFB boiler fire coal coupling solid waste treatment method. A solid waste recycling batch processing system, a closed independent pneumatic conveying system, a boiler stable combustion transformation system and a high coupling combustion proportion technology are included. The discharging mechanism is arranged at the bottom of the stock bin and located between the pneumatic pipeline and the mixing pipeline to form a boot chamber. The ratio of primary air to secondary air is 50: 50%; a lower-layer secondary air nozzle of an original boiler is reserved, and the lower-layer secondary air nozzle is changed to be connected with primary air. A layer of secondary air nozzles are additionally arranged at the position about 2.6 m away from the air distribution plate, and pressing secondary air is newly added; the area of the air distribution plate is 9-10m < 2 >; a low-nitrogen bell type hood is arranged on the air distribution plate; and the separator is an efficient circular steam-cooling d
