This chapter introduces the basic principles governing fuel blending applied to coal–coal blends, with particular emphasis on different ranks of coal. The study of macerals is introduced. Blending coal for combustion and gasification, particularly electricity generation, distinguished from blending for coke production in the steel industry. The combustion and gasification processes are explained. The chemical composition and calorific value of a fuel are discussed. The importance of kinetics, thermodynamics, and ash chemistry are all discussed. |
