gasification 1. Any chemical or heat process used to convert a substance to a gas. 2. The production of gaseous fuels by reacting hot carbonaceous materials with air, steam or oxygen. The process takes place at high temperature. The gasification product is a mixture of combustible gases and tar compounds, together with particles and water vapour. Depending on the gasification method, the proportion of components varies, but common to all the processes is that the gas has to be purified before it can be used directly in a gas engine or a gas turbine (1. 任何化学或热转换过程,使物质变为气体。 2. 通过热碳材料与空气,蒸汽或氧气的反应,生产气态燃料。这个过程需要在高温下进行。气化产品是一种可燃气体,焦油化合物的混合物,同时还有微粒和水蒸气。根据不同的气化方法,混合物的组成比例各不相同,但所有过程的共同点是,气体在直接进入引擎和燃气涡轮机之前会被纯化。) |
