Investigation of Method to Utilize the Waste Heat to Improve the Plant Performance in Sugar Industry

In sugar factory, turbine exhaust steam is used to boil the juice. After boiling the juice exhaust steam loses its latent heat and changes its phase to water. It is called “condensate water”. Now exhaust condensate from process house taken to the boiler feed water tank (storage tank) then by transfer pump it pumps to deaerator. After deaeration, through boiler feed pump, pumps to boiler. In this system at feed water tank there is a heavy heat and water loss through flash. But in modified system, the exhaust condensate from process house to direct deaerator, eliminating the feed water tank and transfer pump which saves water flashing, vapour loss and also saves energy of pump operation.
