Hi All, I want to know your opionions/suggestions for my case. A supercritical boiler operating operates 260 kg/cm2; 570 C at SH outlet header, and we have 2 permanent steam blowing lines tapped from SH outlet header ends. Each steam blowing line is designed with 2 block valves (V1, V2)from...

Hi, if one company decides to install permanent steam blowing line (blowoff line) to the atmosphere for Supercritical coal fired boiler (of course the steam blow pressure will not be the same as boiler operating pressure, the steam blow pressure would be 20% from boiler operating press). The...

thanks Duwe, but i dont think so because it is blowdown/blowoff, what i am looking is the steam blowing. Shall i considered as steam piping (Boiler external piping, b31.1) since it is connected to the SH oulet header and the piping will have 2 block valves with piping and the block valves have...

Hi, if one company decides to install permanent steam blowing line (blowoff line) to the atmosphere for Supercritical coal fired boiler. The installation is done by modifying the superheater header at each side. what are the related clauses for this steam blow line in asme section 1. thanks.

Hi All, Please share your opinion. can UT replace RT for tubes subject to furnace radiant heat with diameter below NPS 4 (DN 100) and thickness below 0.5 in. (13 mm). ASME Section I, 2011, table PW-11, general notes (g), requires thickness below 0.5 in shall be RT, while in the table for tubes...

@mical , i think all my questions i threw were in a polite sentence , and i said thanks to everyone for all the answers. Im a new member and considered my self as junior. I am sorry if my question is considered too easy or vague to you or artisi but i never force anyone to answer me. I think it...

I have tried google before ur comment. I think you are a cocky and not a "right to the point" person. If you dont have it just say you dont have it or just dont reply.

P@ artisi and everyeone , could you please share links free download hydraulic institute code for centrifugal pumps , and blowers and compressor. I only have API 610 , and i always use that. Thanks

Thanks All , @Artisi , the reason is that before project , contract shall be produced which may contain code and standard. Codes affect project cost.

Hi All, any other code and standards for centrifugal pumps in specific in power plant industries besides API 610 (petroleum, petrochemical, natural gas)? thanks

Hi All, please share your thought and opinions as follows: 1) what is the strictest code and standard for designing and constructing underground / buried GRP pipe for big diameter such as 2700 mm (code and standard AWWA M45, Asme section b31.3 non metallic pipe, or BS 7159), any summary of the...

Hi All, Anyone can give the comparison between semi dry and wet type FGD in terms of initial investment, operational and maintenance, cost in the long term, environmental concerns, and byproduct of each system are sellable? thanks

Thank you all for sharing your opinions.. I think the motor S1 duty type is suitable for this kind of operation. I see same examples and the motor are still in good condition.

Hi thanks for responding , basically im asking can i run a pump cyclic with the conditions and specifications bove without really affect the pump motor life time? I see examples in industries that service water from service water tank that supply to service water pump and directed to the...

Hi All, I would like to know the impacts to life time of a centrifugal horizontal pump and motor with flow 80 m3/h, Head 100 meter, fluid water, motor 75 kW , insulation F, duty type S1 with cyclic operation around 24 cycles per day, each cycle is 6 minutes. is the S1 motor duty and pump are...

hi All, I want to have your opinions about PF, and reactive power: 1) why does generator with PF 0.85 lag to 0.9 lead have better flexibility in the Grid than PF 0.9 lag to 0.9 lead? is it because they can work in lower grid voltage? 2) our grid regulating body requires power plant to have...
