摘要
在汽轮机能量平衡方程的基础上，对汽轮机相对内效率与理想循环热效率的概念进行了讨论，指出汽轮机采用回热循环或中间再热后，其相对内效率与理想循环热效率间存在较强的耦合性。最后，建议汽轮机热力试验中应该对回热系统运行条件等对汽轮机相对内效率的影响进行修正。
Based on the energy equation of steam turbine, the discussion on the concepts of relative inernalefficiency and ideal cycle heat efficiency is done.The strong coupling characteristic between relative internal efficiency and ideal cycle heat efficiency for regenerative or reheat steam turbine is pointed out.Finally,the advice is proposed that the correction for the effect of regenerative heat system to relative inlernal efficiencyshould be made in thermal performance test.
