摘要
建立了以汽轮机凝汽器端差替代清洁因数的解析算法,推导了相关参数对凝汽器端差的影响并建立了修正计算方法。这为掌握凝汽器冷却水管内部脏污程度提供了不需额外投资的监测手段,有利于进一步提高机组经济效益,具有实际意义。
The analysis algorithm of cleanliness factor replaced with condenser end difference of steam turbine is formed,the influence of various parameters change on condenser end difference is deduced and its correction method is presented,which provides monitoring measures to control the level of fouling of water pipes without extra investment.It is of practical significance to improve economical benefits of units.
