Burner Control Unit

A Burner Control Unit, also known as a burner control box, is an electronic device responsible for controlling the entire operating sequence of a burner, including start-up, ignition, flame supervision, and system shutdown in the event of a fault. The device plays an important role in ensuring safe and stable burner operation while meeting the technical requirements of industrial combustion systems.

Nam Viet Thermal Equipment Co., Ltd. specializes in supplying genuine Burner Control Units from leading brands including Brahma (Italy), Siemens (Germany), Lamtec (Germany), and LenxTi. Our product portfolio includes a wide range of Gas Burner Control Units and Oil Burner Control Units for new installations, maintenance, and replacement of gas, oil, and dual-fuel burner systems. For Brahma, Nam Viet currently distributes popular models such as CE11U, CM391N.2, G22, GF2, SM152N.2, SR3, TGRD62, VM44G, RE3, SM592N/S, NDTM12, VM41 and VM42.

All products are genuinely imported, offering reliable quality, high operational dependability, and compatibility with many industrial burner models.

Operating Principle of a Burner Control Unit

A Burner Control Unit operates according to an automatic sequence designed to ensure that the ignition process is carried out safely and accurately. The operating sequence may vary depending on the model and burner type, but it generally includes the following steps:

• System start-up: Checks the power supply and safety signals before operation.
• Combustion chamber pre-purge: The burner fan operates to ventilate the combustion chamber and remove any remaining gas or fuel.
• Ignition: The control unit activates the Ignition Transformer and sends a signal to open the fuel valve, allowing the flame to form.
• Flame supervision: Monitors signals from an Ionization Electrode or UV Flame Detector to confirm that the flame has been established and remains stable.
• Normal operation: After the flame is confirmed, the control unit continues monitoring the burner throughout operation.
• Safety lockout: If no flame is detected within the safety time (TS), or if the flame is lost during operation, the control unit shuts off the fuel supply and places the system in lockout mode to maintain safety.

This is the basic control sequence applied to most Brahma Burner Control Units for gas and oil burners, helping the system operate reliably, reducing the risk of flame failure, and protecting equipment during use.

Applications of Burner Control Units

Burner Control Units are widely used in various industrial heating systems, including:

• Gas burners
• Diesel oil (DO) and fuel oil (FO) burners
• Dual-fuel burners
