什么是城市集中供暖

集中供热的优越性集中供热方式有很多优点。首先,可提高,节约能源。大型凝汽式机组的一般不超过40%,而供热机组的热电联产综合热效率可达85%左右。分散的小型烧煤只有50~60%,而区域锅炉房的大型供热锅炉热效率可达80~90%。其次,采用热电站和,就有条件安装高烟囱和高效率的烟气净化装置,从而减轻大气污染,还容易实现当地低质燃料和垃圾的利用。第三,采用集中供热可以腾出城市中大批分散的小锅炉房的占地,减少司炉人员,免除城市中分运燃料和灰渣的运输量,消除这些运输过程中灰尘颗粒的散落,并大大节约用地、降低运行费用、减少劳动力、改善市容和环境卫生。此外,由于集中供热方式容易实行科学管理,还可以提高供热的质量。

城市集中供热系统北京11选5走势图集中供热系统包括热源、热网和用户三个部分。

发展趋势发展城市集中供热应根据城市的具体条件,如密度、采暖期长短、常年负荷大小、燃料价格以及热源建设条件等,选择现实可行、经济合理的方式,并应与密切配合,以充分发挥经济效益。为了进一步提高城市供热的经济性,其发展趋势是:发展大功率、高参数的供热机组;背压式机组带常年;将现有凝汽机组改为供热机组;因地制宜,合理利用工业余热和地热;推广热电站和区域锅炉以及其他热源的联合运行;加大供回水温差;逐级合理利用热能;改进供热管网的结构形式,降低热网造价,延长管子;实现热网运行调度自动化,利用电子计算机对热网工况进行最。有些国家还发展区域供热和供冷的联合系统,在供热管网中同时敷设空调用的冷水管等等。
