What is the difference between a gas turbine and a gas turbine generator? ›

A turbine translates forms of energy into rotation. A generator converts the rotation into electricity. At S.T. Cotter Turbine Services, Inc., we offer exceptional quality turbine and turbine generator service options to help you with all of your gas combustion and steam turbine needs.

Today we announced that the Chubu Electric Nishi-Nagoya power plant Block-1 – powered by GE's 7HA gas turbine – has been recognized by GUINNESS WORLD RECORDS™ as the world's Most efficient combined-cycle power plant, based on achieving 63.08 percent gross efficiency.

Thermal fatigue is a common issue to watch out for in gas turbines. Frequent cycling, corrosion interfering with heat transfer, and combustion issues leading to temperature differences come from extreme temperatures.

A large single-cycle gas turbine typically produces 100 to 400 megawatts of electric power and has 35–40% thermodynamic efficiency.

4 Types Of Engines, Based On The Same Basic Concept

Gas turbine engines have come a long way in the past 100 years. And while turbojets, turboprops, turbofans and turboshafts all have their differences, they way they produce power is essentially the same: intake, compression, power, and exhaust.

The main disadvantage of gas turbines is that, compared to a reciprocating engine of the same size, they are expensive. Because they spin at such high speeds and because of the high operating temperatures, designing and manufacturing gas turbines is a tough problem from both the engineering and materials standpoint.

Gas turbines are often advertised as having fuel flexibility, but the majority of the installed capacity operates on natural gas or LNG because of its purity and ease of combustion.

GE Vernova's 9HA high efficiency, air-cooled gas turbine is one of the industry leaders among H-class offerings, and now the 9HA gas turbine is at the heart of the world's most efficient combined-cycle power plant.

Mingyang Smart Energy announced the MySE 22MW during the China Wind Power 2023 exhibition in Beijing. The turbine boasts a staggering rated capacity of 22 MW and features a 310+ meter rotor, equipped with carbon-fiber blades.

Possible causes. Engine failures can be caused by mechanical problems in the engine itself, such as damage to portions of the turbine or oil leaks, as well as damage outside the engine such as fuel pump problems or fuel contamination.

What is the lifespan of a gas turbine? ›

What is the average lifespan of a gas turbine? With regular maintenance, many gas turbines can operate efficiently for 20-30 years.

The fuels of gas turbines can be classified as liquid or gaseous. Common liquid fuels are kerosene, diesel, crude oil and heavy oil; gaseous fuels include natural gas, liquid natural gas, hydrogen, refinery gas and biomass gasification (synthesis) gas.

A gas turbine operates with a lower electric efficiency (25-35% HHV) than a gas engine. A gas turbine generates roughly twice as much heat as power - ie the heat to power ratio is around 2:1. Unlike a gas engine, all of the heat generated by a gas turbine is high grade (>500 C).

The operation of the turbojet, afterburning turbojet, turbofan, and turboprop engines are described on separate pages. Because of their high power output and high thermal efficiency, gas turbine engines are also used in a wide variety of applications not related to aeronautics.

Every gas turbine engine has a combustion section (red), a compressor (cyan) and a turbine (magenta). The compressor, burner, and turbine are called the core of the engine, since all gas turbines have these components. The core is also referred to as the gas generator since the output of the core is hot exhaust gas.

In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator. The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy.

Gas turbines, also called combustion turbines, generate power using pressurized gas. This is achieved through a three-part process ¹: Air enters into the turbine. A fuel source is burnt, generating heat.
