Description

Gas turbine{GAS TURBINE}

The present invention relates to a gas turbine, and more specifically, to sealing the gap by inserting a seal plate having a wave-shaped spring module into the joint area between the transition piece of the combustor and the case of the gas turbine. ) As it is processed, leakage of fluid flowing from the transition piece into the case is prevented or minimized, and a predetermined protrusion is formed on the valley part of the elastic support member that makes up the spring module, inserted into the groove of the contact plate of the spring module, and then welded. Accordingly, it relates to a gas turbine that can maintain the position of an elastic support member with respect to a contact plate when the seal plate is forcibly inserted into a narrow gap.

The thermodynamic cycle of a gas turbine engine ideally follows the Brayton cycle. The Brayton cycle consists of four processes: isentropic compression (adiabatic compression), constant pressure rapid heating, isentropic expansion (adiabatic expansion), and constant pressure heat dissipation. A gas turbine engine that realizes the Brayton cycle includes a compressor, combustor, and turbine.

The compressor of a gas turbine engine is a part that sucks in and compresses air, and its main role is to supply combustion air to the combustor and supply cooling air to high temperature areas that require cooling in the gas turbine engine. Compressors included in gas turbine engines are usually designed as centrifugal compressors or axial compressors. Small gas turbine engines use centrifugal compressors, while large gas turbine engines need to compress a large amount of air. Therefore, multi-stage axial flow compressors are commonly used. Since the rotating shaft of the compressor and the rotating shaft of the turbine are directly connected, the compressor is driven using a portion of the power output from the turbine.

In addition, the combustor mixes compressed air supplied from the outlet of the compressor with fuel and performs isobaric combustion to produce high-energy combustion gas. The combustor is disposed downstream of the compressor, and a plurality of burners are disposed along the annular combustor casing. Each burner is equipped with several combustion nozzles, and the fuel injected from these combustion nozzles is mixed with air in an appropriate ratio to achieve a state suitable for combustion.

The combustor is the highest temperature environment in a gas turbine engine, so it requires adequate cooling. It is possible to check the flow path through which compressed air flows along the outer surface of the duct assembly through which high-temperature combustion gas flows through the connection between the burner and the turbine, that is, the pipe assembly consisting of a liner, transition piece, and flow sleeve, and is supplied to the combustion nozzle. During the process of compressed air moving along the outer surface of the duct assembly, the duct assembly heated by the high-temperature combustion gas is appropriately cooled.

In general, a number of combustors that make up the combustion system of a gas turbine are arranged in a casing formed in the form of a cell, and each combustor consists of a combustion section that burns fuel to produce high-temperature compressed gas, and a combustion section that generates high-temperature compressed gas from the combustion section. It consists of a transition piece that guides compressed gas to the turbine.

Case 200 forms the outer shape of gas turbine 100.

Additionally, the combustor (300) is disposed at a set interval along the circumferential direction of the case (200) and serves to combust air compressed by a compressor (not shown) by mixing it with fuel.

At this time, the case 200 accommodates the combustors 300, and communication holes 210 are formed to correspond to each of the combustors 300.

In particular, the combustor 300 is a secondary combustion chamber in which a first fuel/air mixture is injected and ignited into the primary combustion zone to generate a main flow of high-energy combustion gases, and a second fuel/air mixture is disposed downstream from the primary combustion zone. It has an axial fuel staging system that injects and ignites the combustion zone.

In addition, the combustor 300 includes a liner 310, a sleeve 320, and a transition piece 330.

In particular, the liner 310 provides a combustion chamber in which fuel injected by the fuel nozzle 312 is mixed with incoming compressed air and burned. At this time, the fuel nozzle 312 is coupled to the front end of the liner 310.

And, the liner 310 connects the transition piece 330 at the rear end to send the combustion gas burned by the spark plug to the turbine section.

To prevent damage to the liner 310 and the transition piece 330 due to the high temperature of combustion gas, the combustor 300 is an annular space formed by the sleeve 320 surrounding the liner 310 and the transition piece 330, that is, , it is cooled by compressed air supplied through the compressed air flow path.

Fuel mixed with compressed air flows through the transition piece 330, passes through the corresponding communication hole 210 into the case 200, and is then supplied to the turbine section inside the case 200.
