Special-tooth-shaped spiral finned tube and tube bundle for cement kiln tail waste heat boiler

The utility model discloses a cement kiln tail waste heat boiler special-tooth-shaped spiral finned tube and tube bundle, which comprises a tube bundle and a tube clamp used for supporting the tube bundle, the tube bundle is formed by connecting a plurality of finned tubes end to end through connecting elbows, the finned tubes are spirally wound on the surface of a seamless boiler tube base tube through special-tooth-shaped fins, and the tube clamp is used for supporting the tube bundle. Tooth parts are arranged on the outer sides of the special-tooth-shaped fins. The finned tube bundle assembled by the special-tooth-shaped fins is adopted, so that the contact area between the finned tube and flue gas is increased, and heat exchange is enhanced. Due to the fact that the special-tooth-shaped spiral finned tube and the tube bundle can enhance turbulent flow of smoke, the purposes of improving the heat exchange efficiency and enhancing the heat exchange effect are achieved. The special-tooth-shaped spiral finned
