Hoow can one estimate the amount of steam required to generate certain amount of electical power mathematicaly?
Broad answer to broad question: From the energy content of the steam and the efficiency of the turbine.Chandrakanth_balusa said:Hoow can one estimate the amount of steam required to generate certain amount of electical power mathematicaly?

Again, the question is very broad, so the response is a basic conservation of energy statement:Chandrakanth_balusa said:thanks for your response!
do u have any mathematical formulae concernig my question?
to be specific , I have some knowledge of how the turbine generators sets work in a steam power plant.russ_watters said:Again, the question is very broad, so the response is a basic conservation of energy statement:
Eout = Ein * Efficiency
If what you really want to know is the details of how a turbine works, I suggest starting with some of your own reading and then asking specific questions about that.
That's an oddly worded question. There should not be a "how long" or rather the answer is: as long as you keep providing it with fuel.Chandrakanth_balusa said:to be specific , I have some knowledge of how the turbine generators sets work in a steam power plant.
i have seen some threads regarding the calculation of turbine output power.
but i wanted to know if there is any possibility to estimate if how long a boiler can serve particular turbine generator set to produce power continously depending on the steam available...
Any introductory thermodynamics book will put considerable emphasis on this. I keep the textbook by Cengel and Boles at my desk (for HVAC)....if possible can anyone suggest me a nice platform or books regarding steam turbines with calculations and some examples!
ok thank you for valuable responses.russ_watters said:That's an oddly worded question. There should not be a "how long" or rather the answer is: as long as you keep providing it with fuel.

There's lots of online resources that look good too, googling "steam turbine thermodynamics".
The power output of a steam turbine is estimated by calculating the mass flow rate of steam passing through the turbine, the temperature and pressure of the steam, and the efficiency of the turbine. These factors are used in the equation P = m * (h1 - h2) * η, where P is power, m is mass flow rate, h1 and h2 are the enthalpy values of the steam at the inlet and outlet of the turbine, and η is the efficiency of the turbine.
The power output of a steam turbine is affected by the mass flow rate of steam, the temperature and pressure of the steam, and the efficiency of the turbine. Other factors such as the size and design of the turbine, the type of fuel used, and the maintenance of the turbine can also have an impact on its power output.
The efficiency of a steam turbine is a crucial factor in determining its power output. A higher efficiency means that more of the energy from the steam is converted into mechanical work, resulting in a higher power output. Therefore, a more efficient turbine will have a higher power output compared to a less efficient one.
Yes, the power output of a steam turbine can be increased by improving its efficiency, increasing the mass flow rate of steam, or increasing the temperature and pressure of the steam. This can be achieved through upgrades to the turbine's design, using higher quality fuels, or implementing better maintenance practices.
The accuracy of the estimates of a steam turbine's power output depends on the accuracy of the data used in the calculations, such as the mass flow rate, temperature, and pressure of the steam. It also depends on the accuracy of the efficiency values used in the equation. In general, these estimates can be quite accurate if the data and efficiency values are measured and calculated correctly.
