The altitude is Not exceeding +1000 AMSL. Can U please explain some more on what will be the "hard time for the engine if it has an emission rating" . What has to be be expected on the cooling system sizing? Thanks to clarify

For an Emergency DG set of 1600 KW , the spec requires Full load run test to be done for 8 hours. But the vendors are offering to have only for 1 hr to 2 hour only. Whether full load test runs duration are based on the capacity of the Generator or for all the Generators? Similarly whether it is...

Thanks a lot catsereng.

One of the Engine manufacturer has indicated Same value as the Rated power of the offered Engine for both the standard conditions as well as for the Site ambient conditions ( in this case it is 54 Deg C) . Is this is technically possible? The DG set is 1600 KW and the manufacturer has...

Thanks to all of you for your replies. Edison 123 the alternator is of Emergency service only. In that case , is it sufficient to have Class F insulation ? Thanks to clarify.

Thank U very much catsereng for your excellent reply. Based on my understanding of your explanation , for an Emergency Diesel Generator ( the engine for my proposal is for the chemical process plant for lining up the DG for critical loads during grid pull out), it is sufficient to have Prime...

For an emergency Diesel Generator set, among the different power rating definitions , Continuous Power (COP) and the Prime Power Rating(PRP)which one is to be selected for which application. For the PRP it is indicated that the average power output is 70% of prime power over 24 hours operation...

An alternator specification calls for Class F insulation with Temp rise to Class B. The ambient Temp max is indicated as 54 Deg C. Is it not enough if we specify the Insulation Class alone.What is the significance of specifying this detail "Temperature Rise"? Thanks to clarify.

Thanks ScottyUK. I have uploaded the filled in data sheet by one of the bidder. In this pl highlight which are the details to be looked into carefully for evaluation .This will be helpful for me to check all other offers also. With regard to the make of the alternator and the engine there is no...

Thanks to electricpete , hoxton & scottyuk for replying and I had got very useful tips from all. The voltage is 415V. Thank you very much hoxton for your detailed reply and I have clearly understood now. ScottyUk, as rightly pointed by you , while reviewing the offer the cost aspect is also...

For one of the Emergency DG set ( 1600 KW), the specification indicates Class F insulation and Overtemperature rise class B. One of the vendor has offered for Class H insulation and Overtemperature rise class B. Class H insulation will give better life than Class F . Is it OK to stick on to...

I have read the abstract of one of the paper presented in CHEMECA 2007 , on "The Guidlines for a motor driven centrifugal compressor package" It seems that the details indicated in the abstract will be very useful to the engineers who have just come to the design field . Can anybody spare a...

Thanks a lot Biginch and JohnGP.

Thanks a lot JohnGP and Biginch. The offered pump have 120 metres head at EOC and even control system at the discharge cannot give the required head of 54M. I think the only available option now is that the process has to put a note in the PDS that for case 1 operation the discharge valve needs...

Thanks to all for keeping replying. I would like to explain the scenario further to get additional comments from you all . Actually this pump is to be installed in the refinery plant for one of the closed drain pump to empty the flare knockout drum within two hours and works intermittent . Two...
