蒸汽纯度对透平机的影响

Influences of steam purity on turbine

蒸汽纯度对透平机的运行有较大影响。蒸汽中的污染物来源于补充水及其中加入的化学品 ,以及工艺冷凝液夹带物等 ,污染物随蒸汽进入透平机后易造成流道结垢与腐蚀 ,导致透平机性能降低与损坏。

The steam purity has an effect on operation of turbine.The pollutants in steam stem from additional water,additional chemicals,and entrainment of condensed fluid.The pollutants entering turbine with the steam can cause dirt and corrosion in fluid channel,which lead turbine to performance reducing and damage.It is important to strengthen the controlling of steam purity and the protection after stop for steady operation with long period.
