Abstract

This paper proposes an automatic operation system for pyrolytic gasification and melting furnaces (PGMF), which is composed of a multivariable model predictive control (MMPC) system and a control function for a daily amount of incinerated waste. MMPC is able to stabilize boiler drum pressure, steam generation rate, fluidized bed temperature and the other condition in the furnaces by manipulating waste feeder speed, a steam control valve and primary air flow. Application results at the first fluidized bed type municipal PGMF in Japan show the usefulness of the proposed method, for example stabilizing pyrolytic gasification process, melting process, energy recovery process and a daily amount of incinerated waste.
