The Role of Modulating Valves in Industrial Combustion
In industrial combustion systems, burners are used to generate heat by burning a fuel and air mixture. The burners are typically controlled by modulating valves, which regulate the flow of fuel and air to the burner.
Modulating valves are used to adjust the flow of fuel and air to the burner in order to maintain a stable and consistent flame. They are typically used in conjunction with a temperature control system, which measures the temperature of the process and sends a signal to the modulating valve to adjust the flow of fuel and air as needed to maintain the desired temperature.
There are several types of modulating valves that can be used for burner control, including pneumatic valves, electric valves, and hydraulic valves. Each type has its own advantages and disadvantages, and the most appropriate type of valve for a given application will depend on factors such as the type of fuel being burned, the type of burner system, and the operating conditions of the process.
In addition to their primary function of controlling the flow of fuel and air to the burner, modulating valves can also be used to shut off the flow of fuel and air in the event of an emergency or to perform maintenance on the burner system. They are an essential component of any industrial combustion system and play a critical role in ensuring the safe and efficient operation of the system.

Experts in Industrial Combustion Airflow Management
To enhance efficiency and achieve optimal process performance, boilers, furnaces, regenerative thermal oxidizers (RTOs), and burners must be calibrated with an optimal air-to-fuel ratio. Measuring airflow is critical to determining this ratio and optimizing combustion. Over time, an efficient system will also result in lower maintenance expenses.
Contact Combustion Technology with Your Natural Gas Fired Industrial Boilers and Package Boilers Applications
Even though natural gas processes tend to burn cleaner than other fuel types, these boilers nonetheless confront particulate-laden airflows. They may be subject to emissions rules if discharged into the atmosphere. These boilers frequently lack precise instrumentation for measuring air and natural gas combustion flow to optimize the air-to-fuel ratio. We can help.
Assistance with Your Power, Biomass, and Recovery Boiler Needs
Whatever the fuel may be, measuring the airflow into the boiler combustion chamber is required to calculate the ideal air-to-fuel ratio. An either too lean or too rich system causes performance or cost difficulties. Emissions problems occur due to faulty burner design or inefficient combustion in boilers. Stop dealing with underperforming boilers and repair underperforming combustion using an air measurement system.
Decades of Experience with Heaters, Furnaces, Ovens, and Kilns
The industrial sector relies on heat from a range of supplied burner equipment to conduct critical process operations, whether for ceramics and glass or annealing and debinding. Fuel prices might be prohibitively high in some procedures requiring extremely high temperatures. Using airflow measurement devices to optimize combustion will save operating costs by increasing efficiencies and improving emissions. Plant managers rely on Combustion Technology's professional application engineers to find the best solutions for improving combustion process efficiency.

Wiring the Siemens Combustion Controls SQM4 Synchro for 4-20 mA Modulation
This video explains the simple wiring of the most common SQM4 Synchro actuator from Siemens Combustion Controls. The "5" board (SQM4x.x5x...) is used with a 4-20mA signal and offers a fantastic alternative to outdated MODulating actuators.
The Siemens SQM4 Synchro is a cost effective modulating actuator with up to 160 in-lbs and 12 or 25 second drive times for 90 degrees. The SQM4 Synchro is suited for driving oil pressure controller, butterfly valves, dampers or for use on other applications that require rotary motion.
SQM4 SYNCHRO FEATURES
- NEMA 4 – No need for weather shields
- No restrictions on mounting orientation – No more elaborate linkages to keep the shaft horizontal!
- The modulating input versions accept 2-10 Vdc, 4-20 mA or 0-135 ohm control signals
Areas of application are oil and gas burners of medium to higher capacity as well as
thermal process plants.
