船舶发动机废气余热利用技术研究

Utilization Technology of Waste Heat from Diesel Engine of Ships

船舶节能技术已经引起广泛关注,其中对于余热和废热的回收是实现节能减排的有效途径。本文分析了船舶柴油机废气的余热量以及余热的种类,介绍了采用朗肯循环系统、海水淡化系统、余热制冷系统等技术手段进行废气合理利用的途径,并介绍了相关的研究进展。

Energy-saving technology of ships has become the world＇s main concern, in which the recovery of waste heat from the diesel engine is an effective way to achieve energy-saving emission reduction. The different amounts of waste heat of the exhaust gas from the diesel engine was analyzed in this paper. Moreover,the comprehensive utilization of Rankine cycle system,seawater desalination systemand waste heat refrigeration system to was introduced respectively.
