What is Burner Management System (BMS)?

A Burner Management System, or BMS, is a safety system that ensures that process burners are started, operated, and shut off safely.

The BMS can be utilized in industries such as oil and gas, power generation, chemical, and any other process that requires an industrial burner, furnaces, boilers, or other flame-producing equipment.

The safe start-up, operation, and shutdown of a boiler is the responsibility of a burner management system. It uses flame scanners to detect and differentiate between the igniter and main flames; safety shut-off valves, pressure, temperature, flow, and valve position limit switches; and blowers to cool the scanners and/or provide combustion aeration.

The Experion ® Process Knowledge System (PKS) and TPS® both have a BMS that provides a single source operator interface. When coupled, the system can grow to encompass engineering, controller, and “burner front” goods and services, resulting in a superior BMS solution. ​

When compared to relay or general-purpose PLC-based systems, Honeywell’s BMS enhances plant uptime, lowers the total cost of ownership, and ensures regulatory compliance. It also enhances worker safety by eliminating the need to access antiquated relay boxes in high-temperature boiler locations. ​

A Burner Management System (BMS) is a safety solution for power plants that allow for the safe start-up, operation, and shutdown of a boiler’s multiple-burner furnace section. It lowers maintenance costs, increases uptime, and ensures a safe working environment for boiler and plant staff.

The energy industry uses a variety of direct and indirect fired heaters in the production of oil and gas. Starting and operating a gas or oil-burning heater can present a real safety risk to the operation of any facility. One way to control this hazard is to install a Burner Management System (BMS) in your process heater.

BMS is an engineered hazard control used by oil and gas operators to ensure the safe start-up, operation, and shutdown of process heaters. It also helps to save fuel costs, reduce maintenance, improve uptime and create a safer environment for personnel working near heaters. A burner management system is also a safety measure to prevent process heaters from exploding in the event of an upset situation.

Burner Management System

Flame detectors can be used to monitor flames, and the system can also control igniters, burners, and actuators such as shutdown valves.

The Burner Management System can have the following functions:

  • Inhibit startup when the conditions are not met
  • Monitor the burner to detect unsafe operating conditions
  • Protect against unsafe operating conditions
  • Shutdown interlocks

When the sensors fail to detect a flame or detect harmful operating circumstances, the BMS instructs the actuators to turn off the fuel flow to the burners, thus suppressing the flames. There are two techniques for deploying a BMS in the industry: Separated or combined The typical approach of building a safety instrumented system (SIS) and a basic control system is the separated technique (BPCS).

The SIS and BPCS logic solvers are housed in two different machines. Workstations and SCADA software are also segregated from each other. Using a bus and a common communication protocol, both systems can communicate with one another.

The integrated method is a new way of putting the solution into action. The SIS and BPCS logic solvers, as well as workstations, are shared in this manner. The logic solver is a program that adheres to industry requirements such as SIL3.

BMS functions :

The fire should not be started until a satisfactory furnace purge has been performed. Allow the equipment to start only after specified permissive interlocks have been performed. During the start-up and shut-down of the equipment, monitor and control the right component sequencing. Allow the equipment to operate on a conditional basis as long as specific safety interlocks are satisfied.

Provide operator and, if equipped, plant control systems and/or data loggers with component condition feedback.

When the equipment is in use, provide automatic supervision and the ability to execute a Master Fuel Trip (MFT) if certain unsatisfactory firing circumstances occur.

When specific adverse unit operating conditions occur, do an MFT.

Types of BMS:

  • separate control
  • integrated control

An integrated system offers:

  • Integrated operating interface
  • Integrated fire and gas detection system
  • Integrated peer control
  • Integrated power supply
  • Integrated diagnosis
  • Integrated security tools
  • Integrated backup and recovery tools
  • Integrated post-incident analysis
  • Integrated simulation and optimization tools
  • Fast data exchange due to direct communication

  • Less flexible
  • Two separate systems are easier to manage
  • Separated systems lead to reduced long-term administrative costs
  • Components of the Burner Management System
  • component objective
    Burner This is where fuel, oil or gas is mixed with air and burned to produce heat. Large heaters often have multiple burners where the combustion process takes place.
    Controller A microprocessor used to sequence or control a burner system’s fuel valve and igniter(s) through processes that include purification, ignition, operation and shutdown.
    Flame detector It is a device which helps in sensing the absence or presence of flame and provides a proper signal to detect it.
    Igniter This is a device that is permanently installed to provide the ignition energy to ignite the main burner.
    Valves are used to control or stop the flow of gas or oil in the fuel system.

The Benefits of a Burner Management System

  • Personnel safety is improved.
  • Protection for burners and furnaces — replacement costs and downtime are quite expensive.
  • Due to compliance with appropriate industry standards such as NFPA, IRI, and FM, you may be eligible for cheaper insurance premiums.
  • Our systems are completely constructed, programmed, and rigorously tested for field installation, lowering start-up expenses.
  • Using annunciation to simplify unit operation.
  • BMS systems can help increase the overall performance of the plant, reduce occupation charges, and control obedience in the plant.
  • The use of BMS can help increase the safety of workers and reduce the chances of accidents on site.
  • eco-friendly
  • In addition to protecting against the risk of natural gas explosions, using BMS also helps reduce greenhouse gas emissions.
  • Less cost
  • It helps in reducing expenses by reducing intervention and shutdown times and ensuring quick recovery from process disturbances. In addition, it requires less maintenance and less training requirements to operate, thus reducing overall ownership costs.
  • Better reporting capability
  • It helps to simplify the operation of the unit by providing alarm notifications and sending operator assistance messages.
