THE HEAT TRANSFER RESISTANCE OF A DEPOSIT ON THE GAS SIDE OF THE BOILER TUBES AT HINKLEY POINT 'A' NUCLEAR POWER STATION AND ITS EFFECT ON STATION ELECTRICAL GENERATION
Abstrakt
Hinkley Point 'A' Nuclear Power Station historically experienced a decline in electrical generation capability of about 30 MWe. This paper describes the identification of the cause of this deterioration as a thin porous carbonaceous deposit on the gas side of the boiler tubes. The theoretical and experimental investigations which showed that this deposit had an effective thermal conductivity of about 0.05 W/m/K are described.
Current progress with deposit removal is presented showing that a substantial improvement in boiler performance has been achieved. This has increased station output by about 20 MWe, thus significantly helping to restore electrical generation capability to historic levels.
