Coal chemical fluidized bed drying gasification slag combustion treatment system

Provided is a coal chemical fluidized bed drying gasification slag combustion disposal system. The water content of the gasified slag is higher than 50%. A coal ash pipeline is easily blocked during conveying, safe operation of the boiler is influenced, and meanwhile, the efficiency of the boiler is possibly reduced due to high moisture. The system comprises a gasified slag feeding device (1), a circulating fluidized bed hearth (2), a separator (3), a heat exchanger (4), a dust remover (5) and a gasified slag burning boiler (7), the gasification slag feeding device is connected with the fluidized bed hearth, the fluidized bed hearth is connected with the separator, the separator is connected with the heat exchanger, and the heat exchanger is connected with the dust remover; an exhaust pipeline of the dust remover is connected with the gasified slag burning boiler; the dust remover is connected with an ash bin, and the ash bin is connected with the gasified slag burning boiler through a fan. The method is used
