What is the problems should be avoided ? We offer you the best solution how to solve it ‘An average 46,500KW power plant gas turbine with normal fouling and showing just a 3% power decrease and 1% heat rate increase can suffer a loss of performance costing more than $500,000 every year.’ Fouling refers to the accumulation of unwanted material on solid surfaces causing an undesirable roughness. In a gas turbine compressor this means deterioration in the aerodynamic form of the aerofoil blades and annulus surfaces, resulting in reduced air flow, lower efficiency and a lower pressure ratio. These losses of performance are indicated by a decrease in power output and an increase in heat rate which means lost profits and increased environmental damage. TYPES OF FOULING Hydrocarbons The worst fouling problems are caused by mixtures of liquids and oils or generally hydrocarbons, which deposit on the blades and form an oily film which catches dry particulate matter. This could be caused by the
