Solid fuel composition and power plant fuel flexibility
N.J. Simms, Cranfield University, UK
A fundamental part of any power plant system is the fuel that it uses. For solid-fuel-fired systems, the composition of the fuels affects every aspect of the plants, from fuel handling and storage, through the fuel conversion process (e.g. combustion or gasification) and heat recovery/energy generation to the gas cleaning systems and environmental emissions (by gas, liquid or solid streams). Traditionally, coals have been used in large scale power plants, but now biomass and waste fuels are being introduced to reduce net CO2 emissions and to increase the consumption of more sustainable fuels. This chapter outlines the main types of ...
