[0034] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0035] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 As shown, a method for using a circulating fluidized bed roasting and rotary integrated furnace is characterized by:
[0036] Step 1, the coal is fluidized and combusted in the hearth 24 of the circulating fluidized bed coal-burning furnace II, and then enters the cyclone separator 23. The larger high-temperature solid particles separated by the cyclone separator 23 enter the return system 25, and the high-temperature solid particles are returning The standpipe 28 of the feeder 26 forms a material column. There is a U-shaped valve 29 between the standpipe 28 and the return pipe 30. The bottom of the U-shaped valve 29 is equipped with an equal pressure air chamber to ensure the fluidization of high-temperature solid particles. The pressure difference between the material column and...
