Combustion Inside the Boiler, Ansys Fluent CFD Simulation Training
In this project, combustion inside the boiler has been simulated, and the simulation results have been investigated using ANSYS Fluent software.
The present model is designed in 3D via SpaceClaim. The boiler is designed so that airflow enters from the side panel of the boiler, and a combination of fuel flows enters through the narrow pipes of the lower part of the boiler, and the boiler outlet is related to the upper pipe of the boiler.
The meshing of this present model has been generated by Ansys Meshing software. The element number is 4694637.
Boiler Methodology
The present simulation is about the combustion inside a boiler via ANSYS Fluent. Boilers are pressurized tanks that carry out the boiling or heating fluid. Boiling is a process that brings the temperature of a fluid to the boiling point. Therefore, the combustion reaction must occur inside these boilers.
The combustion reaction occurs in the computational zone of the boiler, and the desired species are defined using the species transport model. Nine different species are defined to define the combustion reaction, and five combustion reactions between these species are defined as volumetric.
The current boiler consists of two inputs: airflow inlet and fuel flow inlet. Airflow with a temperature of 303.15 K and mass flow rate of 3.375 kg/s enters from the side of the boiler, and a combination of several different fuels with a temperature of 300 K and mass flow rate of 0.6135 kg/s enters from the narrow pipes of the lower part of the boiler.
Moreover, the realizable k-epsilon model and energy equation are used to solve the turbulent fluid equations and calculate temperature change within the domain.
Boiler Conclusion
After the solution, 2D and 3D contours related to each defined species’ temperature, velocity, and mass fraction, including oxygen, carbon dioxide, water vapor, CH4, C2H4, C3H4, and C4H10, are obtained.
The contours show that after combining carbohydrates with oxygen, a combustion reaction occurs, and, as a result, the boiler interior temperature rises.
Also, as the combustion reaction begins, carbohydrates and oxidants decrease at the boiler inlet, and in turn, carbon dioxide and vapor are produced as reaction products, and their amount increases.
