民用燃煤污染控制技术及对策

CONTROL TECHNOLOGIES AND STRATEGIES OF CIVIL-COAL BURNING POLLUTION

我国煤炭资源丰富,作为煤炭生产和消费的第一大国,而民用燃煤的燃烧利用近年来得到了更好的关注。民用燃煤来源广、数量多、分布广,燃烧时存在低空排放、直燃直排、燃烧效率低、未安装末端处理设施等问题,导致民用煤燃烧排放到空气中的污染物贡献值很大。在文献调研中发现,民用燃煤的控制技术有前端控制、燃烧过程控制、末端控制和其他方法控制等。选取了不同的煤型进行了煤质分析和排放因子的检测,并对多类节能环保型燃煤炉具、适用煤种、适用区域、性能指标等开展调研测试工作,并比较了其他处理措施的经济、环境因素,为对策的提出提供了有力的证据。

China’s coal resources are abundant, and as the world’s largest country in coal production and consumption, it makes outstanding combustion and utilization of civil coal. The civil coal has wide range of sources, large quantity, and wide distribution, and there are problems such as low-level emission, direct combustion and direct emission, low combustion efficiency, and lack of installation of end processing facilities, thus resulting in a large contribution of pollutants emitted by the combustion of civil coal into the air. In the literature investigation, it was found that the control technologies for civil coal combustion included front-end control, process control, end control, etc. We have selected different types of coals for coal quality analysis and emission factor testing, and conducted investigations and tests on various types of energy-saving and environment-friendly coal-fired stoves, applicable coal types, applicable areas, and performance indicators, etc., and compared the economic and environmental factors of all treatment technologies, providing strong evidence for the proposal of the strategies.
