What are your control parameters for TDS levels in the B.F.W.? High TDS levels can contribute to foaming and water/solids carryover into the steam. Ask NALCO about an antifoaming agent, it's probably a good place to start.

They have not gotten back with me for 3 days (I'm not entirely impressed with there tech support right now)so I thought I would ask if anyine had previous experience with this since we have already dropped the temp to the inlet steam and may drop it some more (I kindda need to know very...
rmw,
Maybe you misunderstood my question. Yes we have consulted a Mollier diagram and GE is already in the process of running an energy balance for us. The fact that it will take more steam to produce the same power output as the design inlet temp would produce is a given. Increased flow rates...
Due to recently increased production rates at the cogen plant that i work at, we have been sending low superheated steam to one of our Turbine generators. The design parameters for the inlet steam to this GE turbine are 540PSIG at 750F. Steam as low as 680F is regularly sent now to the T.G. and...
Due to recently increased production rates at the cogen plant where i work, we have started to send low superheated steam to one of our GE turbine generators. The design parameters for the inlet steam to this turbine are 540 PSIG at 750F. We have send steam as low as 680F and i wanted to know if...
Due to increased production rates at our cogen plant, we have been sending alot of low superheated steam to one of our turbine generators. The design parameters for the inlet steam to this GE turbine are 540 PSIG at 750F. We have been sending steam as low as 680F recently and I wanted to know...
Sorry for the previous confusion, Thank you hacksaw for the correction I did in fact mean non-condensible gases, primarly oxygen and CO2 (which under boiler conditions can form carbonic acid). Secondly, the congen plant I work at generates steam at 560 PSIG and 150 PSIG (from waste heat and...
I work with DA's at a cogeneration plant and all of the ones I have ever delt with maintain an inlet pressure of 5 PSI (If of course you are using cogen steam to deaerate) and a constant Temp of 230F. Oxygen and other uncompressable gases (like CO2) are usually most insoluble under these conditions.
