[0002] The main sources of air pollution are the random emission of factory exhaust and the burning of large amounts of fuel. Harmful gases include carbon monoxide, nitrogen dioxide, sulfur dioxide, etc., and greenhouse gases include carbon dioxide, methane, nitrous oxide, etc. It is urgent to study the emission of gases at the source to control the emission of harmful gases. However, in actual industrial production, the exhaust gas is generally high temperature and accompanied by a large amount of dust. If accurate gas analysis is to be performed, the smoke must be purified and dusted, which places high demands on the smoke sampling system.

[0003] According to the national standard GB / T16157-1996.
