NEW METHOD OF OPTIMAL DESIGN OF IGCC BASED ON THE CHARACTERISTICS IN ALL OPERATING STATES

On the base of the characteristics in all operating states, this paper proposes a new method of optimal design of combined cycle system of IGCC. The traits of optimal design and the characteristic rules in all operating states of IGCC system are studied in this paper based on the idea of all operating mode and independent variable. In order to realize the innovation in simulation analysis method and evaluation criteria and break through the traditional design framework of thermal system based on the design point, the paper analyzes and compares some cases using the new method. The analytical results show the performance of IGCC system in all operating states is more close to the practical operation situation. The research achievements will provide the valuable method for the design, optimization and operation control of IGCC system.
