Combustion engineering is the study of how fuels burn and the processes involved in converting fuel into energy. This field focuses on understanding the chemical reactions that occur during combustion, as well as the design and optimization of combustion systems, such as engines and power plants. Professionals in combustion engineering work to improve efficiency and reduce emissions, making energy production cleaner and more sustainable. They often use tools like computational fluid dynamics to model combustion processes and develop technologies that enhance performance while minimizing environmental impact.
