Abstract
Fuel and oxidizer are the two essential ingredients of a combustion process. Fuels can be classified as substances that liberate heat when reacted chemically with an oxidizer. Practical application of a fuel requires that it be abundant and inexpensive, and its use must comply with environmental regulations. Most fuels currently used in combustion systems are derived from non-renewable fossil sources. Use of these “fossil fuels” contributes to global warming effects because of the net-positive amount of carbon dioxide emissions inherent to their utilization. Fuels derived from biomass or from other renewable means represent potentially attractive alternatives to fossil fuels and are currently the subject of intensive research and development. Topics covered in this chapter include: (1) different types of fuels (fossil fuels, biofuels, and hydrogen), (2) fuel usage in the United States, (3) basic considerations when choosing a fuel, (4) identification of fuels by their molecular structure, and (5) properties of liquid fuels.

Ethanol and dimethyl ether (DME), which happen to be chemical isomers, have been considered as potential fuels for the future. At ambient conditions, determine the phase of these two fuels.
