一、(火用)(火安)分析的基本概念一种形式的能量并不总是可以全部地转变为任意另一种形式的储量,其中,可转换形态的部分叫做(火用)(Exergy),不可转换形态的部分称为(火安)(Anergy)。机械能、机械功以及电能所包含的是纯(火用),环境的内能所包含的是纯(火安),热能则包含着(火用)和(火安)。从工程经济观点出发,能量中(火用)所占的部分越多,则其价值越高。可见,(火用)是能量的质量指标。 I. Basic Concepts of Exergy Analysis A form of energy is not always fully convertible into any other form of stock, in which parts of the convertible form are called Exergy ), The part that is not convertible is called Anergy. Mechanical energy, mechanical energy and electrical energy contained in pure (exergy), the environment’s internal energy contains pure (fire safety), thermal energy contains (exergy) and (fire safety). From the engineering economy point of view, the more energy (exergy) part, the higher its value. Visible, (exergy) is the quality of energy indicators.
