山东地区农村清洁取暖方案环境效益分析

Environmental Benefit Analysis of Clean Heating Scheme in Rural Area of Shandong Province

以山东某农村地区为例,分析当地传统分散供热及用户使用情况,根据现状可利用能源类型提出清洁取暖的改造方案,并通过理论计算的方法对改造前后能源消耗、主要污染物排放量及其经济性进行计算分析和对比,结果表明,经改造每个采暖季可节省标准煤21.6万吨,SO2排放量可降低83.2%,氮氧化物的排放量降低78.1%,烟尘的排放量降低82.5%,环境综合收益率可达81%。

A rural area in Shandong was taken as an example to analyze the local traditional decentralized heating situation and the user usage,a scheme for clean heating renovation was given.Additionally,Energy consumption and emissions of major pollutants before and after heating retrofit are calculated through theoretical methods.In addition,economic analysis is performed.The results show that 216,000 tons of standard coal were saved,SO2 emissions can be reduced by 83.2%,NOx emissions by 78.1%,soot emissions by 82.5%,and the comprehensive environmental yield can reach 81% after the transformation,in each heating season.
