摘要：

A numerical simulation study was conducted for a jetting fluidized bed coal gasifier with a conical distributor. It was based on a steady-state model which took account of hydrodynamics, mass heat transfer and reactions in the grid zone, bubble zone and freeboard zone of the gasifier. Temperature of the particles and gas in the jet, compositions in the dilute phase and the dense phase, and some hydrodynamic characteristics were calculated. Effects of some operating conditions such as oxygen and steam flow rates, bed temperature and bed pressure on the temperatures in the jet and gas compositions in the gasifier were numerically investigated.
