High-resolution analysis and research on metal temperature of supercritical steam turbines
Aiming at the problem of abnormally high metal temperatures of the low-pressure rotor bearings (#6 and #7) of a 1000MW supercritical steam turbine (N1000-25.0/600/600 type) during low-load operation, this paper systematically analyzes the key factors causing the temperature rise in combination with the working principl...
