Problems solved by technology

[0004] However, there are still some differential expansions that cannot be compensated by using existing pushrod mechanisms, which results in expansion build-up at the ends of the turbine system, thus requiring a significant amount of axial play in the design of the turbine
[0005] The pushrods currently used are rigid, which does not allow to reduce the expansion difference in rotor trains with two or three low pressure turbine configurations

Abstract

A turbine system with a push rod arrangement is proposed. The turbine system includes: a first turbine (22) having a first rotor (28); a second turbine (24) having a second rotor (32); End (66) is coupled to the casing of the first turbine (22) and at the second end (68) to the casing of the second turbine (24), characterized in that the push rod (54) includes a equipment (52, 72).

Description

technical field [0001] The present invention relates to a turbine system for use in a power generation system, and more particularly to a push rod arrangement for a turbine system for use in a power generation system. Background technique [0002] The power generation system includes a turbine system such as a steam turbine system that utilizes a condenser to condense exhaust steam generated in a boiler to drive the turbine system; this steam is converted to liquid water to be recirculated through the system. The turbine system includes high pressure turbines, medium pressure turbines and low pressure turbines. A generator is coupled to a low pressure turbine via a drive shaft to generate electrical power. [0003] During operation of the power generation system, the turbine system is heated. The casing and rotor of a turbine are usually made of different materials and thus expand to different degrees. More specifically, the thermal expansion of the rotor is greater than ...
