摘要
以山西省某县城为例,依据当地供热规划、热负荷分析和热源分析,将集中供热工程一级管网主干线的供、回水管径通过常规式供热和大温差供热两种方案进行经济对比分析,证明选择合理的主干线管径可以有效避免集中供热工程在今后的二次投资,经济效益明显。
This text with Shanxi province some county city for example, be according to the region provided for heat to program, hot carry an analytical and hot source analysis, provide concentration to hot engineering one class tube providing of the net main trunk line, backwater tube the path provide through a normal regulations type hot be provided for hot two kinds of projects to carry on with big difference in temperature economy contrast analysis, prove choice reasonable of main trunk line tube the path can effectively keep concentration from providing hot engineering＇ s again invest in aftertimes, the economic efficiency is obvious.
