针对某热电厂中压供热系统 ,提出了采用两级蒸汽喷射压缩器用于实现高压新蒸汽抽吸部分低压蒸汽、供应中压蒸汽的设想 ,并进行了蒸汽喷射压缩器设计计算、运行经济性分析 ,计算表明这种技术方案存在较大的经济性 ,蒸汽喷射压缩器的使用值得推广 Aiming at the medium-pressure heat supply system of a thermal power plant, a two-stage steam jet compressor is proposed to realize the high-pressure new steam pumping partial low-pressure steam and to supply medium-pressure steam. The steam jet compressor design calculation and operation economy analysis , The calculation shows that this kind of technical scheme has greater economy and the use of steam jet compressors is worth to be promoted
