Caluculations for various parameters in the Thermal power plant

Hello Friends,

I need caluculations in the thermal power plant such as Boiler caluculations(Boiler efficiency),condenser ,airpreheater , turbine etc for a Thermal Power Plant

Please send to snipped-for-privacy@yahoo.co.in

Thanks Suresh

This sounds like you need to hire a licensed Professional Engineer with appropriate ability in electrical and mechanical engineering.

Having worked with a couple of thermal performance engineers, I can tell you that it's more than some e-mail message can cover.

Each feed-water heater has DCA (drain-cooler approach delta-T), each heat exchanger has performance numbers (NTU for example), do the drains cascade all the way back to the condenser, or are there pump-forward drains? What goes into the feed-water heaters besides extraction steam?

The boiler you have flue gas analysis (how much water vapor, excess air, unburned carbon & CO), the fuel analysis (ash, moisture, LHV, etc...)

How many different turbines? High press, low press, intermediate? Moister separators? how effective (moisture content at outlet) Reheater performance (how much scavenging steam flow, outlet temperature, drain tank temperature)? How many extraction points? Controlled or uncontrolled?

Main condenser (air leakage, degree of subcooling, turbine exhaust back-pressure). Air ejectors? How many stages? Where do you get the motive steam, straight from the boiler or a reboiler?

Pumping systems, turbine driven, motor driven, variable speed or throttle valves?

Even where do you get shaft-sealing steam from, and how much?

The list is *very* long, those are just the 'highlights'.
