| Abstract: | The steam leakage from final superheater and reheater occurred frequently in a 600 MW supercritical boiler after 2 years of its commercial operation.The frequent start-stop operation of unit and the reduction of operation parameters make coal consumption and auxiliary power consumption greatly increase.In order to improve the unit efficiency and reduce the cost of power generation,the transformation of the final superheater and reheater heating surface is carried out.The paper introduces the modification process,analyzes the effect of the transformation on saving energy and reducing consumption,and calculates the economic benefits of the transformation. |
