Burner Management System BMS

What’s BMS for the Process Burners Equipment like Boilers , Furnaces ⁉️ How it Works ⁉️ How it’s Important as Part of PSM of Process Plants ⁉️

Answer :-

🔥 Burner Management System or BMS is a safety system used to assure safe start-up, operation and shut down of process burners.

💥 The BMS can be used in industries like Oil and Gas, Power Generation, Chemical or any other process that uses an industrial burner, furnaces, boilers or other equipment that uses a flame.

☀️ The system can monitor flames with flame detectors; it manages igniters, burners and actuators, like shutdown valves.

⭐️ The Burner Management System can have the following functions:

1️⃣ Inhibit startup when conditions are not met

2️⃣ Monitor the burner to detect unsafe operating conditions

3️⃣ Protect against unsafe operating conditions

4️⃣ Shutdown interlocks

🔥 When the sensors don’t detect the flame or detects unsafe operating conditions, the BMS signals the actuators to stops the flow of fuel to the burners, to inhibit the flames.

💥 Fixed heaters are extensively used in the oil and gas industry to process raw materials into unstable product in a variety of processes.

🔥 Fuel gas is normally used to fire the units that heat process fluids. Control of the burner system is critical in order to avoid firebox explosions and uncontrolled heater fires due to malfunctions and deterioration of the heat transfer tubes.

⭐️ Principle functions of the BMS are provided with programmed ignition of igniters and burners at lightoff, flame monitoring during boiler operation, and proper furnace shutdown.

✅ The function of the programmed ignition system is to minimize the boiler furnace firebox explosion hazard, which generally occurs during burner ignition. During normal operation a flameout may occur triggering an explosion.The programmed system allows a quick return to service, which would avoid mistakes by an operator during an emergency.

🔥 The flame monitoring detector provides an on/off signal to indicate the presence or absence of flame within a designated space.The detector typically provides a signal relative to the intensity and distance between the flame and sensor. In the absence of the flame the detector will operate to shut down the boiler.

💥 The boiler shutdown is accomplished through the burner management system by shutting off all fuel to the burners and simultaneously initiating a post-firing purge.
