燃气轮机余热回收技术比较研究

摘要

介绍了燃气轮机余热回收的几种方法，如燃气-蒸汽联合循环，蒸汽回注，导热油回收，以及利用燃机的高温烟气驱动吸收式制冷装置冷却进气等方面的研究。通过对比研究，提出余热制冷技术中所存在的问题及各技术适用的领域。%Several methods to collect the excess hot of gas turbine were introduced, such as gas - steam combined cycle, steam reinjection, conducting oil recovery and driving inlet air cooling of absorption type refrigerating unit with the high-temperature gas. Some problems and suitable application scope of the different techniques were purposed according to the comparative research.
