ENERGY AUDIT OF CONDENSER AND CONDENSER COOLING WATER SYSTEM

5.Energy Audit of CW System.ppt 2374K   View   Download     please see the ppt also  Steps Involved in Energy Audit The major energy consuming equipments in the CW systems are: •Cooling towers and fans •Cooling water pumps •Make up water pumps •Condensers The steps involved in conducting energy audit of cooling water and cooling tower are: •Data collection •Observations and Analysis •Exploration for energy conservation measures •Report preparation  Exploration of Energy Conservation Possibilities •Internal Running Clearances: The internal running clearances between rotating and non-rotating elements strongly influence the turbo machine's ability to meet rated performance. Proper set-up reduces the amount of leakage (re-circulation) from the discharge to the suction side of the impeller •Reducing work load of pumping: Reducing of obstructions in the suction / delivery pipes thereby reduction in frictional losses. This includes removal of unnecessary valves of the system due to changes. Even system and layout changes may help in this including increased pipe diameter. Replacement of components deteriorated due to wear and tear during operation, modifications in piping system
