Techno-economic analysis of IGCC power generation systems based on fluidized bed gasifiers

A computerized techno-economic model that can be used to predict the thermal, environmental and economic aspects of integrated gasification combined cycles (IGCC) using fluidized bed gasifiers was developed. A brief description of the model is presented and representative applications of the model are demonstrated with a case study. The results verify the favourable characteristics of IGCC systems (i.e. high thermal efficiency, low levelized unit electricity cost, and reduced pollution emissions) and illustrate the effect of various parameters on the performance of IGCC power plants. Models for IGCC with moving bed and entrained bed gasifiers are presented elsewhere.
