摘　　要：根据600MW亚临界机组汽轮机通流改造的设计结果,对锅炉再热器改造方案的影响进行分析,优化锅炉再热器改造方案,并对优化后的改造方案进行校核计算。改造效果表明:75%THA以上工况锅炉再热蒸汽温度达到了额定值540℃,50%THA工况再热蒸汽温度提高了11℃,提高了机组运行的经济性。According to the design results of 600MW subcritical unit steam turbine flow path optimiza-tion, analyze the influence of boiler reheater reconstruction scheme, optimize the scheme of the boiler reheater, and the optimized reconstruction scheme is checked and calculated. Reconstruction results show that More than 75%THA conditions of the boiler reheat steam temperature reached the rated val-ue of 540℃ , 50%THA condition of reheat steam temperature increased by 11℃ , improved the opera-tion efficiency of the unit.
