What is the efficiency of the turbo generator?
What is the efficiency of the turbo generator?
Turbine exergy efficiency increases from turbine power of 500 kW up to 2700 kW, and maximum exergy efficiency was obtained at 70.13% of maximum turbine developed power (at 2700 kW) in each operating point. From turbine developed power of 2700 kW until the maximum power of 3850 kW, exergy efficiency decreases.

Is steam turbine renewable?
Steam from renewable sources Providing a future-proof source of electricity and contributing to lower CO₂ emissions, power produced from biomass or solarthermal heat is increasingly economically viable. Hundreds of Siemens steam turbines powered by steam from renewable fuel have been installed worldwide.
What are the efficiencies of turbine?
Turbine efficiency is the ratio of actual work output of the turbine to the net input energy supplied in the form of fuel. For stand-alone gas turbines, without any heat recovery system the efficiency will be as low as 35 to 40 per cent.
Why do we reheat steam?
Why Reheating of steam is used? Explanation: Work output = work done by turbine – work done by compressor. Explanation: Since work output increases the steam rate decreases. Explanation: Efficiency = work output / heat supplied, heat supplied is less in this condition only.
Why is steam used to rotate the turbine?
When steam blows into the turbine, the spinning blades (fitted inside the outer container) are flown at higher rates. Because of high pressure, the continuous flow of electricity is generated at incredibly high speed, therefore the rotating speed increases when comparing with other wind and water turbines.
