Hello,
For HRSG drum manhole, our spec. calls for spiral wound gasket vs our supplier came back with deviation to use steel trap (STM) gaskets. I have not heard but is that allowable?
Thanks in advance.
I have general question. On Steam turbine LP section, I have typically seen rupture discs for the protection from the over pressurization. In a new project, ACC, Air Cooled Condenser supplier is providing Rupture discs covering the Steam turbine LP portion volume as well. In this case, can we...
For a large Steam turbine Generator (300 MW class), any preference for dedicated current transformers for each phase vs multi core current transformers?
i.e. One multi core CT on line and One multi core on Neutral side vs 9 on line side and 9 on Neutral side.
Any suggestion?
Thanks in advance !
