we are going to build a new power station in riga/latvia and are looking for a local supplier of basic engineering of water/steam piping, vessels, pumps etc. the supplier shall be able to provide both engineering and hardware supply including turnkey erection. any ideas if there are some...

i was also working in the utility power business with "normal" condensing turbines where we always put the make-up into the condenser. this is now a different business: the turbine is of the backpressure type where the exhaust pressure is ranging from 0.3 bara to 2.0 bara. the question...

hello jebb66, is there also a disadvantage in putting the condensate into the condenser instead of the deaerator? is the deaeration capability of the condenser sufficient for a make up supply of 4% total cycle turnover? are the ejectors or vacuum pumps also working with a condenser operating in...

what are the advantages/disadvantages of adding the make up water into the feedwater storage tank deaerator versus adding it into the condenser? our dearator tank pressure will always be above ambient pressure. the condenser of the backpressure turbine will be operating in vacuum and also above...

many thanks to everybody for the very usefull information. in a first step i'm going ahead with the heat balance estimation model from "zeven". i already ordered TDP-1 to be on the safe side.

ok. here some more information: steam from two HRSG's (fired by gas tubines) is collected in a HP header and let to a steam turbine. the steam parameters upstream ST are: t=470DegC p=35bara flow=10kg/s (steam from 2 HRSG's) there is also a steam extraction feeding a district heating condenser in...

i am trying to dimension the drain lines of a power station steam piping system. what are the dimensioning criteria? i would assume it is the condensation of saturated steam admitted to the cold piping during startup. are there any thumb rules to design the drain system properly to ensure proper...
