Abstract:

Abstract:Taking the 1000MW unit of Huadian Laizhou Power Generation Company Limited as example, the composition of the turbine lubricating oil cooler system was introduced. The reasons of leakage of the oil cooler before and after reformation were analyzed. Relevant treatment measures were proposed, and good result was obtained. But the defects of the design can not be overcome, which needs to sum operation experiences and to improve the design for solving the leakage problem thoroughly.
