✦ Synopsis

A steady-state numerical simulation model, which takes account of hydrodynamics, mass transfer, heat transfer and reactions, was proposed for the grid zone of a jetting fluidized bed coal gasifier with a conical distributor. Temperatures of theparticle and gas in the jet, compositions in the jet and the annulus as well as gas velocity, particle velocity, particle hold-up in the jet were calculated based on this model. The results have shown that the calculated particle temperature in the jet and compositions in the jet and annulus coincide with the experimental ones those were measured in a laboratory scale jetting fluidized bed gasifier.
