Flue gas continuous monitoring

 

Flue gas emissions of various boilers, industrial kilns and incinerators in industry of building materials, thermal power generation, metallurgy and chemical will cause serious pollution to the environment. Continuous monitoring of the exhaust smoke can not only monitor the effect of desulphurization and dust removal, but also achieve the purpose of environmental protection.
