My tryst with Steam Turbine: June 2014
https://mytrystwithsteamturbine.blogspot.com/2014_06_01_archive.html
My tryst with Steam Turbine. My experience with Steam Turbine. Friday, June 6, 2014. Why most people think that -0.9 Kg/cm2 gauge is the correct value of Condenser Vacuum? Most Steam Turbines in India are designed considering Cooling Water Inlet Temperature of 33 degC and temperature rise of 9 degC through the Condenser. Assuming Terminal Temperature Difference (TTD) of 4 degC the saturation temperature at Turbine exhaust works out as follows. CW Inlet Temperature Temperature rise through Condenser TTD.

My tryst with Steam Turbine: Effect of Atmospheric Pressure on measurement of Condenser Vacuum.
https://mytrystwithsteamturbine.blogspot.com/2013/06/effect-of-atmospheric-pressure-on.html
My tryst with Steam Turbine. My experience with Steam Turbine. Wednesday, June 12, 2013. Effect of Atmospheric Pressure on measurement of Condenser Vacuum. I have following measurements of Condenser Vacuum for 210 MW units in two locations:. Tuticorin TPS -662 mmHg CW Inlet 33.15 degC outlet 43.3 degC. Nasik TPS -658 mmHg CW Inlet 28.3 degC outlet 36.15 degC. The absolute pressure for the measurement would be:. Tuticorin -662 760 = 98 mmHg = 130 mbar. Nasik -658 712 = 54 mmHg = 72 mbar. Please note that ...

My tryst with Steam Turbine: Beware! Steam Turbine Deposits of 1929 to 1936 have surfaced once again.
https://mytrystwithsteamturbine.blogspot.com/2013/02/beware-steam-turbine-deposits-of-1929.html
My tryst with Steam Turbine. My experience with Steam Turbine. Wednesday, February 27, 2013. Steam Turbine Deposits of 1929 to 1936 have surfaced once again. At one IPP in India H. P. Heater Safety Valve blew when the machine suddenly touched 103.6% of rated load. Maintenance Engineer thought that the original Safety Valve setting could have been disturbed but on checking the data in DCS it was found that the extraction pressure had actually reached the set value of Safety Valve to blow. Engineering Expe...

My tryst with Steam Turbine. My experience with Steam Turbine. Tuesday, May 14, 2013. Pump assisted Siphon in CW System of Turbine. To understand the content of this post please read Wikipedia Page on Siphon. Once through CW systems are relatively unknown in Thermal Power Plants being constructed today but there are many old ones. Let us look at following image on Wikipedia page. B can be the top point of Condenser Water Box and C the end of the outlet pipe. Once through Cooling Water. Pump assisted Siph...

My tryst with Steam Turbine. My experience with Steam Turbine. Sunday, January 13, 2013. Required Dew point of air for Gas tightness test of Generator and of Hydrogen when unit is running. I also checked it at 4 barg air pressure and the value is 14.9 degC. Is it ok to fill this air? NO This is winter season and the temperature of air will go below 14.9 degC resulting into moisture in Generator. Is a handy tool to convert. The converted Dew Point should be atleast 20 degC below the Gas Temperature.

My tryst with Steam Turbine: Important Feed back for KN series Steam Turbines of BHEL.
https://mytrystwithsteamturbine.blogspot.com/2013/08/important-feed-back-for-kn-series-steam.html
My tryst with Steam Turbine. My experience with Steam Turbine. Monday, August 12, 2013. Important Feed back for KN series Steam Turbines of BHEL. As per Report of BHEL. The KN series Steam Turbines were introduced in 1997. As per the Report there were lot of problems initially and combined HP IP modules called K Turbine were sent back to works and LP Turbine called N turbine were also rectified at site. Thus the KN series. This is an important feed back for these machines. In case the extraction stea...

My tryst with Steam Turbine. My experience with Steam Turbine. Friday, August 30, 2013. Comments on Press Reports comparing Chinese Power equipment with BHEL supplied equipment. I have started my career as Engineer Trainee in BHEL Haridwar in 1973. I was Erection Engineer and erected 4 out of 5 Turbines of 200 MW at Obra from 1977 to 1982. I left NTPC in 1996 and worked in DLF Industries, ALSTOM and NASL. My experience at Jharsuguda tells me that Dongfang Steam Turbines are no way inferior to BHEL Steam ...
