Integrated process of two-stage fluidized bed gasification and flash low-burning of magnesite

专利摘要:
An integrated process of two-stage fluidized bed gasification and flash low-burning of magnesite, in which a fuel is dried / pyrolysed or partially gasified in a pyrolyser, a product of the pyrolyser is further gasified in a gasifier and is subjected to filtration and dust removal to produce a to produce clean gas, the gas is burned in a burner to produce a hot flue gas to quickly calcine the magnesite, a calcined product undergoes a gas-solid separation, a lightly burned magnesium product is ported to a storage tank transport after a cooling treatment. A flue gas preheats magnesite powder and air required for a reaction by a heat exchange system for flue gas after a calcination treatment. This process is highly integrated, has high thermal efficiency, is a continuous and stable process, no tar-phenol water is produced during coal gasification, and the product activity is high and the quality is uniform.
