中化吉林长山化工有限公司造气车间压缩工段有一台两缸四段十四级离心式压缩机，两气缸分别安装在汽轮机两侧。此汽轮机为抽汽凝汽、反动式汽轮机，型号为 ENK40／56／25。由于高压过热蒸汽品质问题，在运行过程中汽轮机转子叶轮、上下持环等部件结垢，影响汽轮机正常运行，造成两侧压缩机打气量下降，影响合成氨产量。自2014年上半年开始，先后利用低压饱和蒸汽对汽轮机进行蒸煮清垢，蒸煮清洗后，汽轮机运行良好，达到预期目标。

Sinochem Jilin Changshan Chemical Co.Ltd.gasification department compression section has a two-cylinder four-segment fourteen-stage centrifugal compressor.Two cylinder are installed on both sides of the turbine.The turbine are extraction condensation turbine and reaction turbine.The model of the turbine is ENK40/56/25.Due to the high pressure steam quality problems, the turbine rotor,Impeller,Upper and lower ring and other parts scaled during normal operation, resulting in the inlet flow decrease of the compressor on both sides,Influence synthetic ammonia production.Since the first half of 2014,Successively utilized low pressure saturated steam to turbine for boiling and cleaning.The turbine works well from then on ,Achieve the desired objectives.
