摘　　要：对冲动式汽轮机和反动式汽轮机的主要特点进行了对比,提出了一种将冲动式汽轮机改造为反动式的方案,并分析了该方案在某300 MW亚临界机组上的应用效果。结果表明:经过反动式改造后,各缸效率明显提升,机组热耗大幅下降。Based on comparisons on the main features of the impulse and reaction steam turbine,a scheme was proposed for retrofitting the impulse steam turbine to reaction type,and application effects were analyzed for adopting the scheme in a 300 MW subcritical unit.Results show that after the reaction type retrofit,the efficiency of each cylinder is improved significantly,and the heat rate declines dramatically.
