Burner Controller
Burner controllers (also known as flame safeguard controls, primary safety controls, or burner management systems) are crucial safety devices used to manage and monitor the safe operation of commercial and industrial heating equipment, such as boilers, furnaces, ovens, and process heaters.
Their primary function is to supervise the ignition sequence, flame presence, and safe shutdown of the burner system to prevent explosions and protect personnel and equipment.
Core Functions of a Burner Controller:
- Pre-purge: Ensures the combustion chamber is cleared of any residual flammable gases before ignition.
- Ignition Sequence: Manages the precise timing for supplying fuel and igniting it (via a spark or pilot light).
- Flame Supervision: Uses flame sensors (UV detectors, flame rods, or IR scanners) to continuously monitor the presence of a stable flame after ignition.
- Safe Shutdown: Shuts down the system safely and immediately (a "lockout" condition) if a flame failure or any other unsafe condition is detected during operation.
Leading Manufacturers and Products
Several global companies manufacture a wide variety of burner controllers designed for different fuel types (gas, oil, dual fuel) and application complexities.
