Abstract |
|
In sugar factory, the exhaust condensate from process house taken to the boiler feedwater tank (storage tank) then by transfer pump it pumps to deaerator. After deaeration, through boiler feed pump, pumps to boiler. 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. By implementing the new method by eliminating the feedwater water tank and feedwater transfer pump, the exhaust steam saved up-to 2.057 MT/hr, as well as deaerator water temperature will be increased up to 106 to 107 oC and save the water flashing, vapour loss and also saves energy of pump operation and finally boiler efficiency increased about 3.98%. |
