(一)燃气轮机的工作原理及性能指标的评定1.工作原理燃气轮机是一种新型的原动机,它和油田上大量使用的往复式内燃机一样,都是利用燃料燃烧所释放出来的热能转变为机械能的一种热力发动机(简称热机)。它和往复式内燃机相同之处在于:都要以空气和燃气作为工质,都要经过进气、压缩、燃烧、膨胀和排气过程才能对外作功。但是,二者之间却又存在着根本的差异:往复式内燃
(A) of the gas turbine working principle and performance evaluation 1. Working principle Gas turbine is a new type of prime mover, which is the same as the large-scale reciprocating internal combustion engine used in the oil field, is to use the fuel released by the combustion heat into mechanical energy A kind of heat engine (referred to as heat engine). It is the same with the reciprocating internal combustion engine is: both to air and gas as working fluid, have to go through the intake, compression, combustion, expansion and exhaust process in order to work outside. However, there are fundamental differences between the two: reciprocating internal combustion
