Preparation system and method of solid fuel for cement clinker production

The invention discloses a preparation system and method of solid fuel for cement clinker production, and belongs to the technical field of fuel preparation in cement clinker. In view of the problem that existing coal gasification by-product gasified fly ash is difficult to utilize and the preparation cost of the fuel required by the cement clinker is high, the invention provides a preparation system of solid fuel for cement clinker production. The preparation system comprises a raw coal feeding device which is connected with a coal milling device, and an outlet of the coal milling device is connected with an inlet of a fuel conveying device through a separation device. The preparation system further comprises a gasified fly ash feeding device which is connected with the fuel conveying device through the separation device. According to the invention, gasified fly ash and coal are mixed and pulverized to be used as rotary kiln fuel, so that the problem that gasified fly ash is difficultto utilize is solved, the
