The utility model discloses a boiler side wall diffuse type adherent air system which comprises a plurality of layers of adherent air bellows which are arranged at intervals in the height direction of a side wall, a plurality of small adherent air chambers are arranged in each layer of adherent air bellows at intervals in the furnace depth direction, and each small adherent air chamber is communicated with the adherent air bellows and communicated with a hearth through at least one adherent air nozzle. Wherein the close-to-wall air nozzle is formed by a water-cooled wall jump pipe, and the close-to-wall air nozzle and the water-cooled wall jump pipe are both located in the close-to-wall air small air chamber; and the close-to-wall air box is communicated with a hot secondary air main air duct of the boiler through a close-to-wall air duct. The boiler side wall diffuse type adherent air system has the advantages that the side wall water cooling wall can be protected, high-temperature corrosion can be slowed do
