A dynamic mathematical model of a pressurized fluidized-bed coal gasification reactor has been developed and used to correlate data from a pilot-scale reactor. The model accounts for pyrolysis, oxidation, char gasification, and subsequent gas-phase reactions, fines elutriation and heat losses from the reactor, and simulates both transient and steady-state operation. If the values of three model parameters are adjusted to fit data obtained during a steady-state operating period, the model yields good predictions of 11 reactor-state variables and the dynamic response to an upset in operating conditions, so provides an excellent basis for adaptive supervisory control of the reactor.
