    700,000 sets of industrial boilers burning, about 1.8 billion tons a year of coal, a ton of coal burned and scattered emissions of pollutants is more than 10 times after large boiler plants and other processing. In other words, burning, emissions of 1.8 billion tons of coal equivalent to more than 18 billion tons of pollution from coal burning power plants.

Industrial boilers are the result of so many pollutants, which is a major cause of low pollutant emission standards. The main difference between the emission limits at least several times, as many as ten times. For example, sulfur dioxide emission limits for small thermal power plant boilers is 18 times.

    Apart from industrial boilers, coal burning for another large bulk - Residents of coal is also one source of air pollution. Feng Weizhong, general manager of Shanghai outside the three plants had previously surging News () said, because China's living no coal desulfurization system, denitrification, dust, total atmospheric emissions 50 million tons of coal will be approximately equal to the family 1000000000 tons of coal electricity generating pollutants.

Among them, more critical, since low-quality coal price, coal is used in the majority of residents are some of the high-sulfur, high ash content of poor quality, and pollutants from these low-quality coal produced through combustion is even more.

    Clean Coal should receive widespread attention from themselves, can really organize haze occurs, but it also will be a more long-lasting war.
