Indirect firing of combined Brayton and Rankine cycles has been considered as a means of utilizing solid fuels such as wood or coal for power generation. Combined cycles utilizing indirect firing offer potentially higher efficiencies than conventional direct fired Rankine cycles. Many thermodynamic alternatives exist for indirect firing; however, technical, economic, and commercial barriers must be overcome for each of these alternatives. This paper reviews several of the options for indirect fired cycles and considers the factors affecting their application to power generation systems.

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.

Several advanced, coal- and biomass-based combustion turbine power generation technologies using solid fuels (IGCC, PFBC, Topping-PFBC, HIPPS) are currently under development and demonstration. A key developing technology in these power generation systems is the hot gas filter. These power generation technologies must utilize highly reliable and efficient hot gas filter systems if their full thermal efficiency and cost potential is to be realized. This paper reviews the recent test and design progress made by Westinghouse in the development and demonstration of hot gas ceramic barrier filters toward the goal of reliability. The objective of this work is to develop and qualify, through analysis and testing, practical hot gas ceramic barrier filter systems that meet the performance and operational requirements for these applications.

Rapid changes in the fuel availability and cost picture, coupled with environmental concerns, emphasize the need to consider new concepts for power generation by industrial plants and electrical utilities. A number of processes are now being developed to produce clean gaseous and liquid fuels from coal and low-grade petroleum products which offer potential for use in gas turbine-based power generating systems. This paper reviews several of the processes and considers the economic and environmental factors affecting their application to power generation systems.
