| Abstract: | The exceeding the standard value of silica content in steam results in scale in impeller and passing components of turbine completed for air separation plant, which lowers the load of turbine and impairs the normal run of air separation plant. The scale is removed through boiling cooking with low pressure saturated wet steam so as the make the turbine recover to its normal load. Here, the course for analyzing the causes and parameter variation of impeller and passing components of turbine are briefed, and the procedures of boiling cooking method and the preventive measures are described. |
