Combustion system with high velocity mixing tube and flame holder
A recently granted patent (Publication Number: US11906160B2) discloses a combustion system designed to efficiently support a combustion reaction. The system comprises a fuel distributor, an oxidant source, a mixing tube, and a perforated flame holder. The mixing tube is shaped to convey the fuel and oxidant at a velocity higher than flame propagation speed, ensuring a shorter residence time than the chemical ignition delay time. Additionally, the flame holder is strategically positioned to support the combustion reaction within or adjacent to it, enhancing the overall efficiency of the system.
Furthermore, the patent details various configurations and features of the combustion system, including the use of streamwise vortices, flow diverters, bluff body flame holders, and recirculation of flue gas to optimize the combustion process. The system's design allows for the stable and controlled combustion of fuel and oxidant mixture, with specific arrangements such as cylindrical, faceted, or conical input faces for the flame holder. By incorporating elements like bluff body members and diverter mechanisms, the system aims to enhance combustion stability and efficiency. Overall, the patent highlights a comprehensive approach to combustion system design, focusing on maximizing performance and minimizing ignition delays for improved operational effectiveness.
