ABSTRACT
Fuels can be classi–ed in several ways. From a combustion device perspective, the critical aspects of a fuel are how it is transported within the combustion device and how it is combusted. Based on this, combustion engineering classi–es fuels primarily as gaseous, liquid, or solid, and in this book we will follow this convention. After an initial discussion of combustion fundamentals, we address gaseous, liquid, and solid fuels in separate sections, in which fossil fuels and biofuels are discussed.
