Some varieties of gas turbine engines (e.g. RR Trent and RB211) have 3 concentric rotating shafts. Each shaft connects a compressor with a turbine. The low pressure compressor, or fan, is driven by the low pressure turbine. The high pressure compressor is driven by the high pressure turbine. Between the low and high pressure compressors there is an intermediate pressure compressor and, guess what... it's driven by the intermediate pressure turbine.

What is the wheel chamber pressure in turbine?
Resistance offered by turbine to the steam
What is purpose of rapture disc in steam turbine?
when increase the turbine pressure it s add to the rapture disc and it s will be broken and reduce the pressure.
What is difference bw condensing and non condensing steam turbines?
A condensing turbine uses all the energy from the steam going from high pressure turbine to secondary turbine to condensing turbine then sends the condensate back for reheating. where a non condensing turbine just uses the high pressure aspect of the steam then returns the low pressure stream back to be reheated. Condensng turbines utilises the entire available drop from high pressure to the vacuum in the condenser; a back pressure turbine only utilises only the top part, whereas an exhaust steam turbine utilises only th bottom part of the pressure drop. Hope that helps.
What is balance piston line of Turbine?
it is used balance axial thrust on turbine rotor due to admitting of high pressure steam in to turbine. it basic purpose is to save thrust bearing.
What is the uses of packing steam in turbine?
The main uses for packing steam in a turbine are to produce electricity and power. The steam creates pressure when in turn spins a turbine at very high rates of speed.
What is mix pressure turbine?
mix-pressure turbine
What is the difference between 500MW and 600MW power station?
The ans is with respect to Thermal Power plants: the basic difference between a 500MW plant and 600MW palnt is in the turbine design. the 600MM turbine has 1 HPT, 1IPT and 2 LPTs, 2 Condensors and a generator. the 500MW turnbine has 1 HPT, 1IPT and 1 LPT, 1 condensor and a generator. HPT: high pressure turbine IPT: intermediate pressure turbine LPT: low pressure turbine
What is the percent of electricity produced by the process of heating steam to power a turbine in USA?
I can't answer for fossil (high pressure) cycles, but for the Nuclear Steam Supply Cycle (intermediate pressure) the efficiency is about 33%.
What is the wheel chamber pressure in turbine?
Resistance offered by turbine to the steam
What turbine does not require draft tube?
Draft tube is used to increase the pressure from the low turbine exit pressure to the pressure of the surrounding to which the fluid is rejected.Only reaction turbines require a draft tube as there is low pressure at the exit of the turbine,where as in an impulse turbine the pressure at the inlet and the exit is essentially the same, which is above the pressure to which the fluid is rejected and thus it require no draft tube.
Why would you not heat the steam coming out of turbine and feedback to turbine?
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.
What is throttle pressure regulator of a steam turbine?
Essentially its the pressure prior to entering the turbine chamber via the MSV (main stop valve)
What is purpose of rapture disc in steam turbine?
when increase the turbine pressure it s add to the rapture disc and it s will be broken and reduce the pressure.

What is the pressure inside the turbine casing?
a generator
Why the temperature and the pressure of gas are decreasing after flowing out from turbine?
The gas (working fluid) having flown through the turbine does some work on the turbine, converting its thermal energy into mechanical work produced by the turbine and coming out as an expanding gas with lower temperature and pressure.
What is purpose of using Intermediate and Low pressure turbines in a thermal power station?
To obtain as much mechanical energy from the steam produced in the plant's steam raising units as possible, it is expanded through increasing sized turbine wheels, eventually expanding into a vacuum in the turbine condenser before condensing and returning to the steam cycle.
