通过工程实例,详细介绍热电联产机组厂区供暖系统的常规设计方案,并提出供热首站一级网循环水系统混水换热方案作为优化方案。通过对两种方案的初投资、运行费用等方面的比较,可以看出混水换热方案具有无可比拟的优势,同时可实现无人值守自动监控,无需维护,节能效益和经济效益明显。 Through the engineering examples, the general design scheme of the heating system of the cogeneration plant is introduced in detail. The scheme of mixing water and heat exchange in the circulating water system of the first station of the heating station is proposed as the optimization plan. By comparing the initial investment and operating costs of the two schemes, it can be seen that the hybrid water heat exchange scheme has unparalleled advantages. At the same time, unmanned automatic monitoring can be realized without maintenance, and the energy-saving benefits and economic benefits are obvious.
