Embodiment Construction
[0040] In conjunction with the accompanying drawings, the technical route and specific implementation process of the present invention will be described in detail, but the present invention is not limited to specific embodiments.
[0041] Refer to the specific process figure 1 , the first step of incineration: a high-temperature incineration reaction occurs in the circulating fluidized bed furnace 1, the temperature is 900-1200 ° C, the fluidization-heat-carrying medium quartz sand is heated to above 850 ° C, and the fuel is completely produced by pyrolysis. Provide; high temperature quartz sand (≧850℃) is carried by fluidized flue gas and discharged from the flue gas outlet of circulating fluidized bed furnace 1, enters cyclone separator 3 for gas-solid separation, high temperature quartz sand is separated and stored in the quartz sand silo 4. The high-temperature flue gas (800-900°C) enters the air preheater 6 and the steam furnace 7 to recover heat in multiple stages, and ...
