Drying Zones For Heating Slurry In Rotatory Kiln

Petrochemical sludge treatment–Zhengzhou Taida Drying .

Drying is a process which takes advantage of thermal energy, residual heat and waste heat to evaporate moisture fast. The thermal value of petrochemical sludge is always over 4000 kcal/kg. The thermal value of 85% sludge with moisture is only 90kcal/kg. If the petrochemical sludge is burnt directly, it will cost large amount high quality fuels.
