Abstract :
Options to increase waste heat recovery (WHR) power generation in clinker kilns are discussed. WHRS via kiln production process heat re-integration and AQC and SP WHR boilers components integration to maximize WHR rate is discussed. WHR boiler exhaust gas temperature could be greatly reduced via a new dual pressure system by which the WHR rate could be improved. Finally, heat from tertiary air as a high heat source for superheated steam in WHR boilers is reviewed. Rankin cycle efficiency for WHR power generation in clinker kiln could be greatly increased. Finally, Kalina cycle potential application is discussed.
