Dear friends, I have a little bit strange problem: - I should design atmospheric flash tank - mainly for steam line drains and turbine main valve warming up. - Flash tank should be placed in turbine building and collect all live steam line drains and warming up line. Practically it will be...

Hi Sally, I have contacted Alfa Laval - and actually I am waiting for quotation from them. Looks like this type I need is not completely standard - so they have contacted central in Sweden. And it already takes few weeks to make offer. I also think it's possible to use fully welded plate...

If you already have safety valves at steam distribution system which are set to open at lower pressure then design pressure of your HX - than there is no need for safety valve at shell side. The reason for placing valve at shell side could be if your cooling water system is at higher pressure...

Hi Minnesota, I am from Europe - and maybe that's why I don't get all your expressions correct but this are my comments: - usually you vent and drain at start up with manual valves - if you want you can make this valves with actuator (electrical or pneumatic) - but that's expensive solution as...

Problems I see with plate type are: - volume - because this application requires level control of condensate - volume should be sufficient and where to measure level. Maybe to install volume buffer vessel, but where to connect this vessel? - again volume - as it is really important to protect...

Hi to all, Project I am working on involves condensing steam turbine with steam extraction points. Bleeds from turbine should be used for pre-heating of the condensate in 3 stages (3 LP pre-heaters/condensers) - by mean of steam condensation an sub-cooling of condensate. In first stage steam...

I was thinking about rough estimate nothing with going to details. Once I had a handbook with algorithm how to estimate piping costs (I just can't find this book anymore). As I recall it's practically few equations with coefficients. Once again - roughly estimation. I wasn't expecting that...

Hi to all, I need help to estimate costs for piping. It is a boiler plant and I would like to estimate costs for piping inside the boiler house: - steam - feed water and condensate - cooling water - control air - etc. I should somehow estimate (not so precise) costs for piping including: -...

Hi I am working on steam boiler design. And I am using EN 12953 standard. I have some questions, so for now I am just interested if there is someone with experience. At this moment I am not sure how to calculate thickness of manhole plate and how to calculate gusset stays for boiler head...
