Factors that influence gas turbine performance

Jul 16, 20130183;32;For a gas turbine, the vapor condition depends on the type of fuel used and the atmospheric conditions. This is because the inlet to the gas turbine engine is from the atmosphere, and any change in temperature, humidity or pressure will affect the mass flow into, and consequently the power produced by the gas turbine.

Combined Cycle Plant for Power Generation- Introduction

The most common type of combined cycle power plant utilizes gas turbines and is called a combined cycle gas turbine (CCGT) plant. Because gas turbines have low efficiency in simple cycle operation, the output produced by the steam turbine accounts for about half of the CCGT plant output. There are many different configurations for CCGT power plants, but typically each GT has its own associated HRSG,

Gas Turbine for Power Generation- Introduction

Gas turbines are a type of internal combustion (IC) engine in which burning of an air-fuel mixture produces hot gases that spin a turbine to produce power. It is the production of hot gas during fuel combustion, not the fuel itself that the gives gas turbines the name.

Heavy-Duty Gas Turbine Operating and Maintenance

In addition to maintenance of the basic gas turbine, other station auxiliaries require periodic servicing including the control devices, fuel-metering equipment, gas turbine auxiliaries, and load package. The primary maintenance effort involves five basic systems: controls and accessories, combustion, turbine, generator, and balance-of-plant.

Gas Turbine Power Plant Electrical engineering interview

Gas Turbine Power Plant. In a gas turbine power plant, air is used as the working fluid. The air is compressed by the compressor and is led to the combustion chamber where heat is added to air, thus raising its temperature. Heat is added to the compressed air either by burning fuel in the chamber or by the use of air heaters.
