当前,我国大气污染较为严重,主要是直接燃煤的燃料结构造成的。煤烟粉尘主要来自工业锅炉、工业炉窑、生活茶炉、民用炉灶等大大小小的烟囱。煤炭的不完全燃烧是导致烟尘污染的主要因素,据统计,我国煤炭占总能源结构的71％,而日本仅为15％、美国为21％、西德为35％,世界能源构成煤炭比重平均占30％,可见我国煤炭在能源中所占比例甚大,而且在煤炭燃烧
At present, China’s air pollution is more serious, mainly caused by the structure of the fuel directly fired. Soot dust mainly from industrial boilers, industrial furnaces, living stoves, stoves and other large and small chimney. The incomplete combustion of coal is the main factor leading to the pollution of soot. According to the statistics, China’s coal accounts for 71% of the total energy structure, compared with only 15% in Japan, 21% in the United States and 35% in West Germany. The average percentage of coal in the world’s energy composition Accounting for 30%, shows that China’s coal in a large proportion of energy, but also in the coal combustion
