Abstract: Abstract:In a power plant, it was found in unit maintenance that the first stage rotor blade of the M701F gas turbine was damaged seriously. The filter screen in inlet of the compressor was replaced, the turbine cooling air cooler system was reformed, and the operation mode was optimized. Then the rotor blade damage was alleviated effectively.
