“fuel”的概念、定义、翻译、参考文献-科学参考

fuel

Physics

A substance that is oxidized or otherwise changed in a furnace or heat engine to release useful heat or energy. For this purpose wood, vegetable oil, and animal products have largely been replaced by fossil fuels since the 18th century.

The limited supply of fossil fuels and the expense of extracting them from the earth, together with concerns about global warming associated with the production of carbon dioxide, have encouraged the development of nuclear fuels and other sources of energy to produce electricity (see nuclear energy).

Space Exploration

A substance burned to produce heat and power, particularly for rocket propulsion. The most common rocket fuel is liquid hydrogen. An oxidizer, usually liquid oxygen, is also required in order for the rocket fuel to burn in the oxygen-free environment of space. Rocket fuel may be stored as either liquid fuel or solid fuel, and is ignited in the combustion chamber.

Chemical Engineering

1. A substance that has a calorific value and is used for producing thermal energy by combustion. Examples include coal, oil, natural gas, wood, and biofuels. Their controlled combustion is used to release the energy as heat, and conversion to mechanical motion in automotive vehicles, and conversion to electricity in power stations. Primary fuels are (p. 161) those obtained directly from nature such as methane, whereas secondary fuels are derived from primary fuels, such as coke. See combustion.

2. A nuclear fuel is a substance capable of nuclear fission for the production of nuclear energy such as certain isotopes of uranium and plutonium. See nuclear fuel.
