Problems solved by technology

[0004] With the progress of the society and the requirements of environmental protection, the flue gas after combustion and heating is exhausted out of the chimney and discharged into the atmosphere after recovering heat. The flue gas contains a large amount of ash, and also contains alkali metals, sulfur, etc., which will cause air pollution. Therefore, the research and development of a A device with good energy reduction and emission reduction combined with desulfurization and denitrification has become a technical problem to be solved urgently by those skilled in the art
