呼和浩特市目前供热方式主要是以采暖小锅炉为主,95%的采暖锅炉容量在4吨/小时以下,因此采暖季节市区空气污染十分严重。为改变环境,节约能源,呼市规划将由三个热源供给全市采暖。本公司承担的是呼市西郊电厂改为低真空运行,提高循环水温度供城市集中供热工程中管网部份的可行性研究。本文中涉及到的数据和经济指标只是管网部份,而不包括 Hohhot, the current heating mode is mainly based on small heating boilers, 95% of the heating boiler capacity of 4 tons / hour or less, so the heating season urban air pollution is very serious. To change the environment and save energy, the Hohhot plan will be supplied by the three heat sources to the city for heating. The company is responsible for the Hohhot Xijiao power plant to low-vacuum operation, improve the circulating water temperature for urban central heating project in the pipe network part of the feasibility study. The data and economic indicators involved in this article are only part of the network, not including
