Fluidized bed gasification process and device of ash melting polymerization

A gray - agglomerating fluidized-bed gasification method and gasification apparatus, which is prepared by the method of coal, gas, gasification, waste heat recovery and dust composed, in the coal preparation process, adhesion process Needless to be broken. The gasification apparatus from the fluidized-bed gasification unit, a separation unit agglomerating ash, fly ash waste heat recovery unit and the circulation unit composed of, eliminating the need for complex structure manufacturing difficulties in agglomerating the ash in the separation unit venturi throat . In the present invention, while achieving a breaking apparatus sticky coal devolatilization, gasification, ash agglomerating separation, and phenol tar cracking, suitable for strong coals, furnace desulfurization can be performed, in addition, the apparatus manufacturing is easy, simple control.
