Problems solved by technology
[0002] The air preheater is a kind of preheating equipment to reduce heat loss. It transfers the heat carried in the flue gas discharged from the flue at the tail of the boiler to the air before entering the boiler through the heat sink, and preheats the air to a certain temperature. The surface of the existing air preheater will absorb a large amount of soot or sundries after long-term use, resulting in reduced heat conduction effect, and the increase in volume of the air preheater makes cleaning difficult. After the air preheater is taken out for cleaning, install the The operation is more cumbersome, so a heat medium air preheater is needed to solve the above problems
