gázturbinákban

gázturbinákban refers to the use of gas turbines in various applications. Gas turbines are internal combustion engines that work by compressing air, mixing it with fuel, and igniting the mixture. The resulting hot, expanding gases are then directed over turbine blades, causing them to spin and generate power. This rotational energy can be used to drive a generator for electricity production, power an aircraft, or propel a ship.

The primary components of a gas turbine are the compressor, the combustor, and the turbine. The compressor draws in ambient air and increases its pressure. In the combustor, fuel is injected and burned, significantly raising the temperature and volume of the air. This high-energy gas then flows through the turbine section, where its expansion forces the turbine blades to rotate. A significant portion of the energy generated by the turbine is used to drive the compressor, with the excess power available for useful work.

Gas turbines are known for their high power-to-weight ratio, relatively simple design compared to reciprocating engines, and their ability to start and stop quickly. They are widely used in power generation, particularly for peaking power plants that can be brought online rapidly to meet sudden increases in demand. In the aerospace industry, jet engines are a form of gas turbine that provide thrust for aircraft. They also find application in industrial settings for mechanical drive purposes, such as powering pumps and compressors, and in marine propulsion. The efficiency of gas turbines can be further enhanced by methods like combined cycle power generation, where the waste heat from the gas turbine is used to produce steam for a steam turbine.
