Combustion system with pilot and main fuel control
A recently granted patent (Publication Number: US11953201B2) discloses a combustion system comprising a pilot fuel distributor, a main fuel distributor, a distal flame holder, sensors, actuators, and a controller. The pilot fuel distributor supports a pilot flame during a preheating state, while the main fuel distributor outputs fuel during standard operation. The distal flame holder supports combustion of the main fuel and oxidant. Sensors monitor the pilot flame and distal flame holder conditions, with actuators adjusting fuel flow accordingly. The controller receives sensor signals and controls the actuators based on software instructions to optimize combustion efficiency and safety. The system includes features like a perforated flame holder, solid refractory tiles, and sensors for CO, NOX, and O2 levels to ensure optimal performance.
Furthermore, the patent details a method for operating the combustion system, involving sensor signal reception, adjustment of fuel flow, and transition from preheating to standard operation based on sensor feedback. The system also includes a computer-controlled method for adjusting heating settings based on heat demand data, pilot fuel flow, and main fuel flow to maintain optimal combustion efficiency. The system's design allows for manual control inputs and operator prompts on a display for adjustments. Additionally, the system includes safety features like flashback detection and pressure monitoring for enhanced operational safety and efficiency. Overall, the patented combustion system offers a sophisticated and automated approach to combustion control, ensuring efficient and safe operation in various heating applications.
