hi,
Could anyone tell me how to calculate overall efficiency of an extraction cum condensing steam turbine?

There are a few paramters required to caclulate the turbine efficiency.

Actual plant power generation rate
Steam Flow rate from boiler
Specific Steam Consumption
Steam Pressure at Turbine inlet
Steam Temperature at Turbine inlet
BFW Temperature
Enthalpy of Steam at Turbine inlet
Enthalpy of BFW
Steam extracted from the plant
Steam Pressure at Turbine extraction
Steam Temperature at Turbine extraction
Enthalpy of Steam at Turbine extraction
Steam to condenser
Steam Pressure at Turbine exhaust

I have a spreadsheet to allow you to plug and play your data to calculate the efficiency. Check the spreadsheet formulas to determine how to minipulate the data. send me a Private message for the spreadsheet with your email information. for some reason, i cant upload the .xls type file as a message attachment.

Sir can you send me the same spread sheet on my mail ID

awaiting for reply

Can you send me excel sheet

thanks

My friend can you send this spreadsheet to vip900@msn.com
please

thanx for the information

Hi..
A steam turbine is a mechanical device that extracts thermal energy from pressurized steam, and converts it into rotary motion.It has almost completely replaced the reciprocating piston steam engine primarily because of its greater thermal efficiency and higher power-to-weight ratio. Because the turbine generates rotary motion, it is particularly suited to be used to drive an electrical generator – about 80% of all electricity generation in the world is by use of steam turbines. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency through the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible process.
