LVRF5 Cyclonne preheater


Outlet temperature:380-400(℃)

Running rate:>85%


Vertical preheater is a kind of vertical preheater for preheating calcined materials. It is developed on the basis of importing and absorbing foreign advanced technologies. Combined with the characteristics of dolomite and limestone calcination it has reasonable structure high heat transfer rate and high level.

Jiangsu Lvssn’s brand new LVRF5 5-Stage cyclone preheater with precalciner System has adopted our double spraying design of the calciner. Scientific structure with large ratio of length to diameter is able to homogenize material to increase material retention time.BesidesLvssn’s engineers has added rear extended pipe to provide more sufficient material burning space and also increase some the material retention time.There is fully combustion for pulverized coal to increase system efficiency.
    Jiangsu Lvssn has mastered the secrets in the development and application of preheater system with advanced technologies---our 4th generation predecomposition calciner technology on our five-stage Cyclone preheater system.
    Jiangsu Lvssn continuously cooperates with domestic and international famous cement enterprises with extensive technical communications to optimize the structures of cyclone preheater and performance.
    Jiangsu Lvssn’s engineer has also adopted computer flow data simulation to commission our equipment. After our multiple test and practical application our optimized 5-stage preheater system has a significant improvement in its high efficiency and low resistance performance.
