| Abstract: | By using software ANSYS a three-dimensional model was set up for the turbine cylinder and rotor of a marine steam turbine. The thermal expansion during a cold-state startup was calculated and analyzed. Presented are the time-dependent thermal expansion displacement curves and relative thermal expansion curves of the turbine cylinder and rotor at the gland seal of a rear shaft end, and also at other locations. The calculation results may be used for the research of steam turbine dynamic characteristics and the design of startup procedures. |
