Governing of reaction turbines pdf

At the present time, the high-capacity K/ steam turbine for nuclear power plants with WWER reactor are manufactured at the Leningrad Metal Plant and the K/ steam. Tube turbines can be connected either directly to the generator or through a speed increaser. The speed increaser would allow the use of a higher speed generator, typically or r/min, instead of a generator operating at turbine speed. The choice to utilize a speed increaser is an economic decision. If the head at the inlet of the turbine is the sum of pressure energy and kinetic energy and during the flow of water through runner a part of pressure energy is converted into kinetic energy, the turbine is known as reaction turbine. For the axial flow reaction turbines, the shaft of the turbine is vertical.

A typical turbine governing system has two unloaders - one activated by low condenservacuum. and the otherbylow boiler pressure. Theacti­ vatedunloader acts similarly to the loadlimiter, ie. itrestricts the v&lve de­ mand signal, thereby limiting the steam flow, and hence, turbine generator load.

    In my opinion you are not right. I can prove it. Write to me in PM.

    I apologise, but, in my opinion, you are mistaken. Write to me in PM, we will talk.
