Compressor for steam turbine.
(OP)
My plant is wasting a lot of steam so we were thinking of installing a 12MW steam generator. How ever, our steam is to wet and to rich in silica... A a result, we got proposed to use a geothermal steam turbine that are apparently more resistant to bad steam quality... However, they have a bad effeciency and they cost to much..
Is it worth it to consider to super heat our steam that is now at 189degC and 1250kPa and bring it to 4130 kPa (600psi)?

RE: Compressor for steam turbine.
seems a temp increase in steam is better, but then the silica problem needs to be addressed.
how about other alternatives - smaller capacity boiler, lower firing rate on existing boiler, modify piping system such that steam demand matches boiler output, etc.
good luck!

RE: Compressor for steam turbine.
The steam feed comes from what has not been used in our processes. As a result, we dont have a control on boiler operating parameters, because the processes have certain requirements.
Would it be worth it to heat the steam that comes in to decrease the moisture such as the effeciency or the turbine goes up enought to asorb the cost... is there plants doing such thing ?

Yes, they use to compress steam way back when to improve effiencies or recycle steam vents in boiler plants.
