what are the low frequency effects on steam turbine. Are there steam turbines designed with very low frequency protection.

How to carry out test / calculation for finding out tramp air quantity and associated loss in coal fired boilers of 200 MW and above sized. suggest reading material / websites.

I observed mostly exhaust fans in battery rooms. Is it acceptable pressurising fans too. Any standards?

Friends, What are the various standard procedures of finding coal Gross Calorific value.Which of them are very accurate.Where can I get standard procedures

How does a flow control valve characteristics changes if erected in reverse diriection. what effects will it have on it's capacity

How the two frequencies ( 50Hz & 60Hz)came into existence in the world. please explin me background. Also merits & demerits over each other.

Let me know , what are all the properties that ash should have, to pump it in slurry form. How to determine these characteristics? please suggest some reading on internet.

Is there any web site discussing about steam turbine designs and erection

please let me know web sites where i can get all materials mechanical and chemical properties.

Please suggest me good web sites on centrifugal pump design.

I observed in one of the IP turbine efficiencies, coming 95% againist design of 90.27%. This turbine is of HP-IP in one cylinder of 200 MW capacity. Is such a high percentage deviation is possible? (If there is high HP-IP seal passing due to high First stage pressure)

N2H4 + 6Fe2O3 = 4Fe3O4 + N2 + 2H2O IS THIS REACTION UNSATISFACTORY BELOW 150 deg.C AND LEADS TO FORMATION OF AMMONIA. PLEASE EXPLAIN IN DETAIL.

please tell me about the babbit properties that makes it useful for Turbine bearings. please tell about mechanical properties useful for designing it.

I observed in our 500MW boilers prior to tube leakage,ammonia level in feed water and sat. steam is raising by 0.2ppm i.e from 0.45 (normal) to around 0.55 to 0.65 ppm. Explain how is this possible.

we have measured a three phase pump power with a tongue power meter and result is as follows. R Y B current 191.4 197.7 194.5 AMPS power fac. 0.7 0.96 0.27 POWER 33.8 48.2 14.6 KW VOLTAGE IS...
