Poor condition of boiler pressure parts with high erosion, overheating, external corrosion, oxide deposits, weak headers and pressurized furnace etc. Poor water chemistry has affected the condition of boiler and turbine in many cases. The water treatment plant is often in a dilapidated condition. Poor performance of air pre-heaters due to blocked elements and high seal Leakage. Poor performance of the milling system resulting in high unburnt carbon. This was often a result of lack of preventive or scheduled maintenance. Poor condition of Electrostatic Precipitators (ESPs) resulting in high emissions. Problems of high axial shift, vibrations and differential expansion in Turbine Low vacuum in condenser due to dirty / plugged tubes, air ingress and tube leakages High vibrations in Boiler Feed Pumps and Condensate Pumps and passing of recirculation valves, resulting in low discharge
