Why the gas turbine needs 3 bucket stages only in 110MW TURBINE?

The 3 bucket stages in a 110MW gas turbine are designed to efficiently extract energy from the high-pressure hot gas produced by combustion. By using 3 stages, the turbine can effectively expand the gas across multiple stages, thereby maximizing energy extraction and overall efficiency within the power plant. Additionally, the design may also optimize the velocity and pressure of the gas flow to ensure proper turbine performance at the specified power output level.


What is effect if inlet temperature is increased on gas turbine?

Increasing the inlet temperature of a gas turbine can improve its efficiency and power output. This is because higher temperatures lead to better energy conversion and expansion of the gas, resulting in more work output from the turbine. However, there is a limit to how much the temperature can be increased before it affects the materials and components of the turbine, potentially reducing its reliability and lifespan.


Does power station use natural gas to generate electricity?

Yes. There are many power stations that use natural gas to heat water to steam and then turn turbines to generate electricity. These are considered more environmentally friendly than oil or coal powered plants.


How does steam turbine works?

Steam or water, it works the reverse of a fan, where the fan pushes air down, the turbine is turned by the steam or water. there's a shaft leading from the turbine to the generator, which produces the electricity


What are the important parameters in brayton cycle?

The important parameters in Brayton cycle are the pressure ratio between the compressor and turbine, the efficiency of the compressor and turbine, the temperature of the gas at various points in the cycle, and the specific heat ratio of the working fluid. These parameters are crucial in determining the performance and efficiency of the Brayton cycle.

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 the difference between back pressure and absolute pressure in steam turbine?

Back pressure is the small amount of vacuum that is created when the used steam condenses from the turbine back into re-usable water.


How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?

Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.


How do you effect the gas turbine exhaust pressure loss on performance?

Gas turbine exhaust pressure loss negatively impacts performance by reducing the effective pressure ratio across the turbine. This loss can lead to decreased power output and efficiency, as the turbine has to work harder to achieve the same thrust or energy output. Additionally, higher exhaust pressure can result in increased back pressure, potentially affecting the overall system's thermal efficiency and contributing to higher fuel consumption. Managing exhaust pressure losses through design optimizations and control systems is crucial for enhancing turbine performance.


What is intermediate pressure turbine?

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 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 property of the exhaust gas is being used to turn the turbine that runs the compressor?

At exhaust valve opening, pressurised gas reduces pressure by moving across the turbine blades and out of the exhaust pipe, the momentum of the moving gas is tapped by the turbine blades producing torque on the turbine shaft.


What is the need for gas turbines?

gas turbine are used for expansion of high pressure gas,which rotates the rotor coupled with generator and hence electricity is finally produced.Gas turbine operate on brayton cycle.


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.


How a gas turbine work?

Basically, a gas turbine is powered by gas under pressure, The gas is pressurized by burning some type of fuel such as kerosene, jet fuel, or propane. That heat causes air expansion, and the subsequent inflow of air makes the turbine spin. A gas turbine consists of three main parts; a combustion chamber, a turbine and a compressor. Air and fuel are mixed in the combustion chamber where it is ignited and increases in speed and power. This power is directed over the turbine blades which spin the turbine and power the compressor. It's a pretty simple process: heated fuel causes pressure and air expansion. The expanded air causes a turbine to spin. That is how gas turbines like jet engines work.
