THERMODYNAMIC ANALYSIS OF MARINE INTERNAL COMBUSTION COMBINED CYCLE

船用内燃复合循环热力分析吴孟余，章学来（上海海运学院轮电系上海２００１３５）关键词：内燃复合循环，效率，循环分析一、引言为了提高船用内燃机的经济性，近年来，国内外对于复合内燃机的研究方兴未艾。该机既具有内燃机燃烧温度高的特点，又结合了涡轮机排温低、压...

Resently, high efficiency internal Combustion engine and exhaust heat recovery technology have been developed.In combination with maritime case in China, A new adiathermal combined internal combustion cycle was proposed by authors. It was point out that the adoption of by-pass secondary combustion, adiathermal technology, exhaust power turbine and exhaust heat recover apparatus…etc…was used in new combined cycle.By ideal combustion air analysis, compound cycle was analysed with the help of thermodynamical second law. Many irreversible lose on overall cycle was calculated. In this paper, availability efficiency performance and improvable methods of the compound cycle was presented.
