Evaluation of control strategies for fixed-bed coal gasifiers using MGAS

Abstract

The MGAS (METC Gasifier Advanced Simulation) model is used to simulate a moving-bed gasifier. The MGAS code is written in FORTRAN and takes into account details in specifying the reactor geometry, reaction kinetics, etc. Steady-state control analysis tools that use MGAS to uncover the optimal control strategies are demonstrated. These strategies are compared with those that are known to be suitable in the actual gasifier.
