A typical wet process kiln has a fuel consumption per kilogram ( kg ) of clinker produced of between 1,300 and 1,500 kilocalories ( kcal ), depending on the water content of the slurry fed to the kiln. The fuel consumption is approximately 175 of the consumption of a dry process rotary kiln that is equipped with a preheater and precalciner.
A novel approach to modeling mass transfer in rotary kilns is explored. The movement of gas in the interparticle voids in the bed of the kiln is considered, where particles move concentrically with the geometry of the kiln and gas is entrained by these particles. A reactor modeling approach has been used to derive effectiveness factors for the bed as a function of bed fill, reaction kinetics.
Wet Rotary Kiln Delivery . Wet Rotary Kiln Performance Characteristics. Because raw material is made into the mud, it has strong adaptability to heterogeneous raw material, uniform raw material composition, stable process, high quality of clinker, high clinker strength, less dust in grinding process and less fly ash in kiln.
