日前,北京市科委发布全市在大中型火电空冷机组余热利用技术方面取得的重大突破。据悉,该项技术是将北方地区投运的火电空冷机组与城市市政高效供热技术有机结合,提出近距离热用户低品位余热直供和远距离热用户汽轮机抽汽提质耦合的热电联产技术方案,通过乏汽余热回收,在不增加装机规模情况下,扩大了供热能力,同时解决了现有大容量热电联产机组存在供热抽汽节流损失大、供热系统能效低等问题。
Recently, Beijing Municipal Science and Technology Commission released a major breakthrough in the city’s utilization of waste heat in large and medium-sized thermal power units. It is reported that the technology is put into operation in the northern region of thermal power air-cooled units and municipal municipal heating technology and organic combination of low temperature hot users proposed short-range heat supply and long-distance heat turbine steam turbine extraction coupled heat and power Technical scheme, through the waste heat recovery of waste heat, without increasing the installed capacity of the case, expanded heating capacity, while addressing the existing large-capacity cogeneration unit there is heat extraction throttling loss, heating system, low energy efficiency problem.
