Enhancing the Performance of Boilers in Thermal Power Plant

Jul 19, 2016· 4.6 Conclusion:The key step to enhance the performance of boilers in thermal power plant is the detailedstudy of boiler in the plant and then the efficiency calculation. The efficiency calculation byindirect method is the best way to account all the boiler losses. The flue gas loss is alwayshigher than any other losses.
