STEAM TURBINE is a machine for generating mechanical power in rotary motion from the energy of steam at temperature and pressure above that of an available sink. A turbine operated by highly pressurized steam directed against vanes on a rotor.
HEAT ENGINE is a physical or theoretical device that converts thermal anergy to mechnical out put.....it converts heat energy into work.

What is the length of an blade for a gas turbine?
The length of a blade depends on the style (impulse or reaction), the overall size of the turbine, whether it is an axial flow or radial flow turbine, and where the blade is located within turbine of an axial flow turbine. One thing that is constant: the length of the blade increases from the steam or gas inlet to the discharge of the unit. The profile will gradually increase in diameter from inlet to discharge.
Why is the gas turbine called as the power plant?
A gas turbine is one type of power plant. It produces power by burning gas to turn the turbine.
What is turbine overspeed trip?
Typically two balls with springs holding them down, When the turbine spins too fast, the centrifugal force pushes the balls past the resistance of the springs at which point they hit a lever that stops steam/compressed gas flow to the turbine and the turbine shuts down. They are designed to keep the turbine from going so fast that it damages itself or the piece of equipment it is driving.
Difference between saturated and superheated steam?
Saturated steam occurs when steam and water are in equilibrium. If you have a closed container of water and heat it, above 100 celsius the steam pressure will start to rise, and as the temperature continues to rise, the pressure will go on rising. What is happening is that steam is being evolved to match the temperature (steam tables will give this relation) and the steam conditions are said to be saturated because if the pressure is raised by external means, some of the steam will start to condense back to water.If the steam pressure is held at a lower level than that achieved at saturation, by taking steam off to feed a turbine or other steam usage, there is effectively an excess temperature for that pressure, and the steam is said to be superheated. It in fact then becomes dry, and behaves as a gas. The amount of superheat can be quantified as so many degrees of superheat (celsius or fahrenheit). Turbine designers want steam to be superheated before reaching the turbine, to avoid condensation causing blade erosion, and steam producing boilers in power plants are designed to produce superheated steam.
What is the function of IGV in gas turbine?
The function of IGV in a gas turbine is to prevent surges and stall conditions.
What is difference between a geothermal and thermal power plant?
The steam turbine blades to turn creates steam.The steam engine, steam piston Myllng after the turn brings.+++They are both steam-engines. The turbine is purely rotative; the reciprocating steam-engine uses cylinders and pistons.
How does combustion inspection of gas turbine to be carried out?
what the deffrant bettwen steam and gas
What is needed to turn the blade of a turbine?
Wind, water, steam or another liquid or gas.
Where are ratchet mechanisms used?
Ratchet mechanisms used in Gas power plant for Gas Turbine. (like Barring gear in steam turbine).
What is the difference between combined cycle and cogeneration?
In Cogeneration Plant : The generated steam in boiler is used for both power generation & process heating, thereby reducing the condenstion losses compared to thermal power plant. In combined cycle first is gas turbine , rather than wasting the flue gas from gas turbine, we are sending it into boiler and again generating steam for running steam turbine. Both the ways we are increasing the thermal efficiency of the plant
What Supplies The Mechanical Energy In A Generator?
Any moving fluid can power a turbine. This includes air, water, steam, burning fuel etc. When the fluid strikes the blades of the turbime it transfers energy to the blade causing the blade to move.
How do you produce electricity from biogas?
You can use the bio gas to fuel either a steam cycle generator or a gas turbine.
What is used to turn a generator?
A handle, a pair of pedals, a treadmill, a water mill, a petrol engine, a diesel engine, a wind turbine, a steam turbine, a gas turbine.
What relationship exsists between turbine and generator?
A turbine is powered by such things as steam, burning gas or oil, water, or wind. The turbine is a type of engine, which might be thought of as a more efficient choice than a gas engine or reciprocating steam engine for doing the same job. The turbine could do many things ranging from powering a vehicle such as a helicopter, a ship, a locomotive, or a piece of equipment such as a centrifuge, a pump, or a generator. When a turbine powers a generator, the generator makes electricity.
What is the definition of combined cycle turbine technology?
Using waste energy in a gas fired electricity generation plant to run a steam turbine
Are airplanes powered by steam engines?
No. They are powered by internal combustion engines. Or by gas turbine jets.
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
