城市集中供热,可以节约能源,改善环境,提高供热质量,方便人民生活。但是由于供热工程本身耗钢多,造价高,投资大,因此设计方案选择十分重要,热力网投资在整个供热工程中的比重很大,所以热网是否合理对整个工程经济效益起重要作用。 本文就热力网的规划,合理供热范围,热指标,管网参数,敷设方式,热力站连接,经济比较等方面,所应遵守的原则和注意考虑的问题,根据实际工作体会,作了概要介绍。
Centralized heating in cities can save energy, improve the environment, improve the quality of heating, and facilitate people’s lives. However, due to the fact that the heating project itself consumes more steel, the construction cost is higher, and the investment is greater, the choice of design scheme is very important. The investment in the heating network is very large in the entire heating project, so whether the heating network is reasonable plays an important role in the overall economic benefits of the project. . This article gives an overview of the principles of heat network planning, reasonable heat supply range, heat index, pipe network parameters, laying methods, heat station connection, and economic comparison.
