Abstract

According to negative differential temperature between upper and lower cylinder of HP Cylinder in 362MW steam turbine

many parameter data are collected and inner structure of HP cylinder is investigated to solve slip-ring seal jam in steam admission pipe and gland corridor distort.Cylinder and shaft seal cover distortion are thoroughly checked and treated to eliminate excessive high negative differential temperature.
