Abstract:

In Wuxi Western Gas Thermal Power Company Limited, the filter differential pressure of a 9F gas turbine inlet filtration system increased rapidly to the alarming limit in a short period. Analyzing the problems existing in the original design, it puts forward a set of measures which includes improving coarse filtration precision, upgrading fine filter’s filtering material and change outlet of exhausting gas. After the transformation, the filtration system works well, which reduces the operation and maintenance cost, improves the safety and stability of the unit and obtains remarkable economic benefits.
