The chapter deals primarily with the utilization of coal in IGCC systems. Coal gasification for power generation is gaining popularity due to the availability of the raw material (coal) worldwide, reduced environmental-related issues compared to the utilization of coal in combustion technologies, and the ability to capture CO2. To improve the overall efficiency of the IGCC process, an in-depth understanding of various coal properties that influence the design and operation of an IGCC plant is required. These coal properties determine the type of gasifier suitable for the process, the feeding system, the kind of coal preparation required, the amount of oxidants required for the gasification process, the flux to be added to keep the slag flowing, and so on. Besides coal, utilization of other solid feedstocks that are commonly used in IGCC plants, such as biomass and petcoke, are also presented in this chapter.
