Abstract:

<span>One of the main reasons of the performance degradation of gas turbines is the axial compressor fouling due to air pollutants. Considering the fact that the fouling leads to high consumption of fuel, reducing of the axial compressor’s discharge air pressure and increasing of the exhaust temperature, thus designing a compressor degradation detection system will allow prevent such issues. Many gas turbine plants lose power due to dirty axial compressor blades, which can add up to 4% loss of power. In case of power plants, the power loosing could be observed by less megawatts produced

In this paper, we investigated a thermodynamic model of the regeneration gas turbine cycle with nitrogen supplied during the compression process. A suitable quantity of nitrogen that comes from the air separation cycle (Linde cycle) is injected between the stages of the compressor where it is evaporated, then the nitrogen and air mixture enters into the combustion chamber where it is burned and expanded in the turbine. We used this method to reduce greenhouse gases and improve gas turbine efficiency. In this work, we evaluated the operational data of the regeneration gas turbine cycle and the

The most obvious changes in gas turbine performance is a reduction in power and an increase in specific fuel consumption following an increase in the ambient temperature, resulting in significant deviations of the guaranteed (and achieved) values a

Abstract:

A new method for predicting performance of multistage axial flow compressors is proposed that utilizes stage performance curves. The method differs from the conventional sequential stage-stacking method in that it employs simultaneous calculation of all interstage variables (temperature, pressure and flow velocity). A consistent functional formulation of governing equations enables this simultaneous calculation. The method is found to be effective, i.e. fast and stable, in obtaining solutions for compressor inlet and outlet boundary conditions encountered in gas turbine analyses. Another advan

Abstract:

The project made to show the working model of Turbojet Engine. The turbojet engine operates on the Brayton cycle and features four primary stages: air intake, compression, combustion, and exhaust. The turbo-jet engine is for high speeds. The working model shows how atmospheric air is taken in and compressed using a multi-stage axial or centrifugal compressor. The compressed air then enters the combustion chamber, where it mixes with fuel and undergoes ignition, producing high-energy exhaust gases. These gases rapidly expand through a turbine, extracting mechanical energy to drive the compresso

ABSTRACTIn 1997s, East Kalimantan had several oil and gas fields that had reservoir pressure in the High-Pressure category. However, a few years later, the pressure continued to decrease until it reached Low Pressure, so the compressor is needed to produce high-pressure. In this study, an explanation of the process of making a turbine engine performance simulation model in 2019 is discussed and predicting turbine engine performance in the following years. This is important because the compressor is a vital tool in the oil and gas industry. Furthermore, it works continuously so that performance
