Introduction

The utilization of electrical energy in Indonesia plays a vital role in supporting development in various sectors. Among the electricity generation technology, gas turbines that drive electric generators are one of the efficient and effective solutions. This article will discuss the basic principles and steps in the design and analysis of gas turbine combustion chamber by utilizing Ansys software and thermodynamic calculations.

Purpose and Methodology

The combustion chamber in the gas turbine is designed with the aim of analyzing aspects of thermodynamics, such as the temperature and average pressure that comes out of the combustion chamber. In this case, some of the main components of the combustion chamber will also be evaluated. This design process involves two main approaches: the calculation of thermodynamics and numerical simulations using ANSYS.

The thermodynamic calculation method is used to obtain initial data regarding temperature and pressure, which produces a combustion chamber out of 1323 K and a pressure of 9,969 bar. Meanwhile, the simulation using Ansys aims to verify these results by visualizing and analyzing the distribution of temperature, pressure, and hot air velocity coming out of the combustion chamber.

Understanding the Importance of Gas Turbine Combustion Chamber Design

The design of the combustion chamber in the 128 MW electric generator driving gas turbine is very important to optimize the efficiency of power plants. The combustion chamber is a critical component of the gas turbine, as it is responsible for mixing the fuel and air, igniting the mixture, and producing the high-temperature and high-pressure gases that drive the turbine.

Thermodynamic Calculations and Numerical Simulations

Simulation and Analysis Results

The simulation results carried out with Ansys show that the average temperature out of the combustion chamber reaches 1580 K, the average pressure out of the combustion chamber is 9.90 bar, and the average speed of hot air is 651 m/s. When the simulation results are compared with the results of thermodynamic calculations, there are significant differences. The temperature obtained from Ansys was around 19.42% compared to the results of the thermodynamic calculation, while the average pressure showed smaller results, which was 0.6%.

This difference shows that numerical simulations using Ansys are able to provide a deeper understanding of the dynamics of fluid in the combustion chamber, as well as the effects of various operating conditions. Ansys can capture complex interactions between the variables in the system, which cannot be fully covered by a simple analytical calculation model.

Benefits of Using Ansys in Gas Turbine Combustion Chamber Design

The use of Ansys in gas turbine combustion chamber design offers several benefits, including:

Improved accuracy: Ansys can provide more accurate results compared to thermodynamic calculations, which can lead to improved efficiency and performance of the power plant.
Deeper understanding: Ansys can provide a deeper understanding of the dynamics of fluid in the combustion chamber, which can lead to improved design and optimization of the combustion chamber.
Increased efficiency: Ansys can help to identify areas of inefficiency in the combustion chamber, which can lead to improved efficiency and reduced emissions.

Conclusion

The design of the combustion chamber in the 128 MW electric generator driving gas turbine is very important to optimize the efficiency of power plants. By using a combination of thermodynamic calculations and numerical simulations using Ansys, a more accurate analysis of the temperature and pressure of the combustion chamber can be obtained. The results of this study not only contribute to efficient combustion chamber design, but also in an effort to increase the capacity and efficiency of the power generation system in Indonesia.
