Faber supplies comprehensive strategies for the optimal control of combustion equipment and systems. From custom-engineered state-of-the art control systems to rugged, straightforward mechanical control schemes, Faber has a proven solution to best fit your application.
What is a Combustion Control System (CCS)?
A CCS is a key burner subsystem that is composed of equipment that controls fuel-to-air ratio and firing rate. This equipment can be comprised of both mechanical and electronic components, including actuators, flow control valves, linkages, dampers, positioners, PLC’s, process loop controllers, oxygen analyzers, variable frequency drives (VFD), as well as other instrumentation. All of these devices play important roles in the performance and efficiency of the combustion system. Other control requirements are commonly grouped into the category of combustion controls to provide application specific burner functionality, overall control of the equipment being fired, as well as the plant.
Who Should Provide The CCS?
Purchasing the control system, commissioning, and operator training separately from the burner system can make a project unwieldy and expensive. Faber takes a systems approach, integrating controls and equipment to guarantee the seamless compatibility of all components. Applying our combustion experience and design approach to your application is the best way to ensure excellent results.
When Faber Provides A Combustion Control System You Can Expect:
- Maximum Compatibility
- A Product Ready For Operation
- Reduced Commissioning Time
- Superior Training
- Sole Source Responsibility
Faber‘s Design Approach To Combustion Control Systems
We listen to the customer and gather vital details of the project, such as the customer’s present needs and future goals, the type of equipment to be fired, plant/facility processes and load conditions, any fuels to be fired, furnace draft conditions, and environmental conditions. We take the time to properly match the control system to the plant’s operating and maintenance philosophy, which includes the number of staff as well as their skill sets. When retrofitting existing burners with controls, we are able to realistically identify the potential benefits and clearly explain to the customer any weak areas in the burner system design that a control system cannot improve.
Below are some standard offerings that we provide. Although Faber is willing and able to customize control systems to the customer’s needs, we have worked hard to develop a robust set of standard routine systems that we are familiar with, have extensively tested, and support on a regular basis. We use only field-proven devices that have demonstrated reliability and user-friendliness, and keep our standard offerings in stock so that we can service your systems quickly and accurately.
Combustion Control System By Faber
We have the capabilities to provide any type of combustion control system, from straightforward to state-of-the-art.
Commonly Applied Control Features:
- Plant Master Control Station

- Feedwater Control (Single-, Two-, and Three-element)
- Touch screen Operator Interface
- Oxygen Trim Control
- Flue Gas Recirculation Control (FGR)
- Various Communications Available for SCADA / DCS Systems
Commonly Applied Control Schemes:
Single Point Positioning: Featuring a rugged “jackshaft” system, this is the most reliable and cost effective system for boilers up to approximately 90,000 lb/hr steaming capacity.
Parallel Positioning: The fuel flow control valves and air flow control damper are “linked” electrically. This is used on systems with a remote mounted fan when a single point system would be impractical. Typically, this system is used on boilers with a steaming capacity greater than approximately 80,000 lb/hr.
Metering Control System: This system measures fuel and air flow, while positioning the fuel flow control valve and air flow control damper to maintain a predetermined fuel-to-air ratio. Built-in “cross-limiting” ensures that a safe fuel-to-air ratio will be maintained. This system is typically used on larger boilers or when the simultaneous firing of two fuels, such as landfill gas and natural gas, is required.
