中国散烧煤消费地图及影响因素研究

摘要

基于政府监管能力和差异治理方式解析散烧煤内涵范围,建立中国民用散煤消费地图,分省、分领域统计散煤消费,识别出中国散烧煤的重点领域是工业小锅炉和农村生活,集中在东北—西南连线附近的少数省份;定量比较了散煤及集中燃煤的PM2.5、SO2、NOx等排放情况,认为散煤的PM2.5排放量多于燃煤电厂;分析煤炭生产供应、采暖需求、基础设施等因素对散煤消费及分布的影响,提出散煤治理的政策及措施建议.%According to the government regulatory ability and replacement policies,the scattered coal definition is put forward in this paper,China's civil scattered coal consumption map is constructed,the data of scattered coal is provided in each sector at provincial level,and then the fact is identified that industrial small boilers and rural living are the most important areas of scattered coal,which concentrate in a few provinces on the line from the Northeast to the Southwest.The PM2.5,SO2 and NOx emissions from concentrated coal and scattered coal are compared in the study.It can be seen that the PM2.5 emission of scattered coal is more than that of coal-fired power plant.The influence of coal production supply,heating demand and infrastructure on the consumption and distribution of scattered coal is also analyzed,and the suggestions of policy and measures are put forward at last.
