农村地区室内燃烧清洁技术研究

Control Technology on Indoor Pollution of Coal Combustion in Rural Area

介绍了针对农村室内燃煤污染的清洁技术,特别是固氟固硫技术研究的进展。在分析燃煤型氟中毒流行特征的基础上,进行了现场试验,结果表明白云岩或石灰岩可有效阻止燃烧时氟和硫的释放,减少粉尘的浓度,且经济实用;提出了将燃煤固氟固硫清洁技术与炉灶改造相结合,是农村贫困地区防治室内空气污染,保护健康的根本途径。

Control technology on indoor pollution of coal combustion in rural area, especially the progress in technique of coal fluoride-sulfur fixing was introduced in this paper. On the basis of analyzing epidemiological characteristics of coal burning endemic fluorosis, in situ experiments inside farmer＇s houses were finished. The results shown that dolomite or lime- stone can deter emission of fluoride and sulfur from coal combustion effectively and can reduce the content of dust. Therefore combined technique of coal fluoride-sulfur fixing and stove improvement is the best economic and applied way to prevent the indoor air pollution and to safeguard the people＇s health.
