Individual Burner Airflow Measurement
Individual burner airflow measurement gives plant operators the data needed to fine-tune air-to-fuel ratios, improve combustion stability, and support lower emissions. In multi-burner applications, even small airflow imbalances can impact boiler efficiency, heat rate, and overall system performance. Air Monitor provides custom airflow measurement solutions designed for challenging low NOx burner environments, including turbulent flow, angularity, short duct runs, and profile stratification. Each solution is engineered for dependable burner-level measurement and calibrated to support accurate, application-specific performance. Speak With an Application Engineer
Air Monitor Solutions Can Help You...
Reduce NOx and CO Emissions
Accurate burner-level airflow measurement helps operators maintain more consistent air-to-fuel ratios across the furnace. This supports cleaner combustion and helps plants reduce emissions without relying solely on non-repeatable manual tuning.Improve Combustion Efficiency
Better airflow data allows operators to reduce excess air, improve stoichiometric control, and optimize heat rate. In large utility boilers, even small efficiency gains can translate into meaningful fuel savings over time.Minimize Maintenance & Downtime
Air Monitor’s airflow measurement solutions are built for demanding power plant environments where dirty air, turbulence, and difficult duct conditions can create measurement challenges. Rugged construction and optional purge capabilities help keep systems operating reliably with less manual cleaning and recalibration.Individual Burner Airflow Measurement Products
CA Station
The CA Station is a strong fit for individual burner airflow measurement applications where accurate readings are needed in tight or less-than-ideal duct locations.
Its built-in airflow straightening technology helps reduce the impact of turbulent, directional, or non-uniform flow before measurement, giving operators more dependable burner-level airflow data. This supports more precise air-to-fuel ratio control, helping improve combustion stability, emissions performance, and overall boiler efficiency.
VOLU-probe/SS
The VOLU-probe/SS is well-suited for individual burner airflow measurement applications where airflow may be turbulent, stratified, or difficult to measure with a single-point device. Its multi-point averaging design measures airflow across the duct area to provide a more representative burner-level reading, helping operators identify and correct imbalances between burners.
Built for harsh industrial environments, the stainless steel probe supports reliable combustion airflow measurement in clean, dirty, corrosive, abrasive, and high-temperature conditions.
VELTRON DPT-Plus
The VELTRON DPT-Plus supports individual burner airflow measurement by converting low differential pressure signals into accurate, stable airflow data operators can use to manage burner performance. Its automatic zeroing capability helps prevent output drift over time, which is especially valuable in applications where small airflow changes can affect combustion balance, emissions, and efficiency.
When paired with Air Monitor airflow measurement devices, it helps deliver dependable burner-level readings for more precise air-to-fuel ratio control.
AUTO-purge III
The AUTO-purge III helps maintain reliable individual burner airflow measurement in dirty or particulate-laden combustion air environments. By automatically purging sensing ports at selected intervals, it helps prevent plugging that could reduce measurement accuracy or require manual cleaning.
When used with Air Monitor airflow stations or probe arrays, it supports more dependable burner-level data, reduced maintenance time, and fewer disruptions caused by clogged flow elements.
Solutions Designed for Challenging Burner Airflow Conditions
Individual burner airflow measurement is difficult because low NOx burner environments often create turbulent, angular, and stratified airflow profiles. Short duct runs, changing flow conditions, and particulate-laden air can make it challenging to get repeatable readings without the right measurement approach.
Air Monitor designs custom airflow measurement solutions to address these challenges at the burner level. By accounting for real-world duct conditions, flow profiles, and maintenance demands, Air Monitor helps operators capture more dependable airflow data for combustion tuning, emissions control, and boiler efficiency.
Individual Burner Airflow Measurement FAQs
Why is individual burner airflow measurement important?
Individual burner airflow measurement helps operators understand and control how much combustion air is being delivered to each burner. This makes it easier to balance air-to-fuel ratios across the furnace, support lower emissions, improve combustion stability, and reduce excess air that can affect boiler efficiency.What makes burner-level airflow difficult to measure?
Burner airflow can be difficult to measure because low NOx burner environments often create turbulent, angular, and stratified airflow profiles. Short duct runs, dirty air, and changing operating conditions can also make it harder to capture accurate, repeatable readings without a measurement solution designed for the application.How does Air Monitor support accurate individual burner airflow measurement?
Air Monitor designs custom airflow measurement solutions for challenging combustion air applications. Each solution is engineered around the application’s duct geometry, flow conditions, accuracy needs, and maintenance demands, helping operators capture dependable burner-level airflow data for combustion tuning, emissions control, and boiler efficiency.News & Innovation
