分布式能源站燃气内燃机的余热利用方式探讨

Discussion on Heat Recovery of Gas Engine on Distributed Energy System

摘要: 通过对燃气内燃机分布式供能系统的余热来源、余热温度、可利用程度等进行分析，并对余热利用系统设计时需要关注的内燃机排气背压、余热系统烟气阻力及排烟温度等参数等进行研究，最后对主要的余热利用设备的原理及技术应用进行了探讨，对燃气内燃机分布式供能系统余热利用系统方案设计具有一定参考意义。

Abstract: Based on the gas engine distributed energy supply systems, the heat sources, temperature and usability of the waste heat were analyzed. The back pressure and temperature of gas engine discharge and the pressure drop which should be noticed on the heat recovery system design were studied. The work principle and technology of the main kinds of heat recovery equitments were researched. The results provide reference to the heat recovery system design of gas engine distributed energy supply system.
