Optimize Process Performance with Precise Airflow Measurement from Air Monitor
To improve efficiency and achieve optimal process performance, various industrial equipment such as boilers, furnaces, regenerative thermal oxidizers (RTOs), burners must have an optimal air-to-fuel ratio. Measuring airflow is critical to determining this ratio and optimizing combustion. Over time, an optimized system will also result in lower maintenance costs. Plant managers rely on instrumentation such as Combustion Technology ad Air Monitor's expert application engineers to find the best solutions for improving combustion process efficiency.
Applications Requiring Precise Measurement of Combustion Airflow:
Industrial Boilers and Package Boilers Fueled by Natural Gas
Although natural gas processes burn cleaner than other fuel types, these boilers still encounter particulate-laden airflows and may be subject to emissions regulations when exhausting to the atmosphere. These boilers frequently lack accurate instrumentation for measuring air and natural gas combustion flow to optimize the air-to-fuel ratio.
Power, Biomass, and Recovery Boilers
Whatever fuel is used to power the boiler, measuring the airflow into the combustion chamber is required to calculate the ideal air-to-fuel ratio. A system that is either too lean or too rich causes performance or cost issues. Another cause for emissions problems is poor burner design or poor combustion in boilers. Stop dealing with underperforming boilers and fix the incomplete combustion with an Air Monitor airflow measurement solution.
Heaters, Furnaces, Ovens, and Kilns
The industrial sector relies on heat from various sourced burner equipment to perform essential process functions, whether for ceramics and glass or annealing and de-binding. Fuel costs can become prohibitively expensive in some processes that necessitate incredibly high temperatures. Using airflow measurement devices to optimize the combustion of burner equipment will reduce operating costs by increasing efficiencies and improving emissions.

Improved Safety and Performance with Direct Coupled Gas Valve/Actuator Assemblies
Historically linkages are more common than direct coupled actuators. Control actuators were usually foot-mounted. A foot-mounted actuator has the mounting surface on the bottom and the drive shaft coming out the side. This arrangement invites linkage-type control. An example is a four-bar linkage. If any of these bar lengths are changed, it will affect the range and characteristics of the control valve. There are usually six security points in this configuration: actuator to crank arm, crank arm to swivel head, swivel head to linkage rod, and then double all of those for the valve side.
The actuator secured to the valve is critical to safe operation. The actuator becoming disengaged from the control valve is a significant safety concern. There is confidence in the crank arms' security and is considered a positive connection. The swivel heads are less secure. Typically the swivel head is clamped or presses a set screw into the linkage rod. Under conditions of vibration or varied temperature causing expansion and contraction, these connections come loose. Because of this hazard with linkage, you'll occasionally see a position switch connected directly to the valve to verify the valve position.
Because the connections of a linkage are not rigid, there is a problem with hysteresis. The least rigid connections are the swivel connections. The actuator will push on the swivel head when driving open and pull on the swivel head when driving closed. There will be two different valve positions based on the direction hysteresis is created for a given control signal. Why is this important? Hysteresis hurts emissions efficiency and temperature control.
More recent control actuator designs are face-mounted. These newer designs make the mounting surface and the drive shaft on the same plane with the mounting face actuator shaft and valve shaft in line. Direct coupling the actuator to the valve is an improved design.
For direct-coupled control, the stroke of the actuator equals the stroke of the valve. To adjust the stroke of the actuator, change the cams located under the cover to limit the stroke. The concept of cam adjustments in the actuator is commonplace for a direct-coupled arrangement.
There are just two secure connection points with direct-coupled: actuator to coupling and coupling to the valve. When done correctly, both of these points are positive connections. The machining of the actuator side of the coupling is commonly an irregular shape that doesn't allow the actuator shaft to rotate inside the coupling. On the valve side, a pin bolt goes through the coupling and the valve shaft. You can be more confident in a secure connection with a direct-coupled arrangement.
The inline connection of the actuator driveshaft and the valve shaft with a positively connected coupling eliminates linkage hysteresis. The coupling is a rigid piece that directly transfers the actuator movement to the valve movement, providing precise control which assists emissions requirements, optimizes efficiency, and facilitates high-performance temperature control.

Top 5 Gas Flow Meter Selection Criteria
The first and most important feature is that the flow meter is simple to set up and operate.
Nobody enjoys complexities, and your facilities manager is no exception. Choose a simple flow meter to install, requiring little maintenance and not requiring any additional calculations. Make that the flow meter can connect with your DCS, PLC, or control system without difficulty. Knowing that the flow meter has the appropriate certifications for usage in dangerous regions is reassuring and a requirement!
Flow meter precision is the second most important feature.
Who knows what's going on behind the scenes in the pipes? As a result, you'll need a measurement instrument to correctly measure the flow in the pipes and provide you with a window into your process. Have high expectations for the process's correctness across the whole spectrum of operation, whether at high or low flow rates.
Flow meter field flexibility is the third key feature.
Flow meters with limited flexibility that require a return authorization to the manufacturer's factory for modification or recalibration are causing you downtime. Select a full-featured flow technology that allows the user to make adjustments or confirm accuracy in the field. These flow meters will keep you in control of your process and help you prevent downtime.
Flow meter cost-effectiveness is the fourth key feature.
Do your homework and acquire several quotations. Some technologies promise the moon and stars, but the price tag may be prohibitive.
Flow meter reliability is the fifth key feature.
Choose a flow meter that can accurately measure flow over time with minimal effort. The bottom line is that you want to be able to rely on the readings from your flow meter without needing to perform routine maintenance or recalibrations.

Hydrogen Ready Flame Scanners
With the global energy market's increasing need for hydrogen (H2), proper flame detection and discrimination are crucial. Although ultraviolet detection is commonly utilized for H2 flame detection, it is only a tiny part of accurate detection.
H2 is frequently used in conjunction with variable ratios of natural gas or other gasses to produce fluctuating flame characteristics. The wavelength of a typical H2 flame ranges from 220nm to 600nm, most of the time being in the 300nm range. Although this is outside the standard detection range of Gieger-Muller tube technology, contemporary solid-state sensors are more than competent. The flame flicker frequency changes as the H2 / gas ratio changes, implying that proper detection and discrimination require flame scanner technology to address these shifting flame profiles.
Fireye's InSight® scanners have shown to be effective in various H2 and H2 / gas mixture applications. While different flame scanners can detect the UV signal, not all of them have the many frequency settings needed to detect and differentiate. The InSight® range from Fireye features 21 adjustable frequency ranges and the option to keep four alternative sets for multiple fuel variations. These memory values can be changed during detection using two-wire communication. Fireye's InSight® series is available in IR or UV or in a dual UV & IR configuration, allowing you to add IR detection to the flame discriminating profile if necessary. All Fireye InSight® scanners are now available in ATEX and IECEx hazardous environment versions.
Fireye's InSight® Features
- Infrared, ultraviolet or both
- 21 Frequency ranges
- State of the art algorithms • A TEX & IECEx options

Understanding the Importance of Pressure Drop When Using Flowmeters
The pressure inside a pipe can vary from the pressure outside of the process. Friction or a physical obstruction in the pipe may cause a pressure drop in the system, resulting in a loss of line pressure.
Figure 1 shows a high and robust pressure reading at point "A," followed by the pipe narrowing. The pressure reading then drops at point "B." This phenomenon is the definition of pressure drop.
Figure 1: Visual example of a pressure drop in a pipe where a narrowing of the pipe causes a drop in
pressure from point “A” to point “B”.
Maintaining pressure can be vital to the device's operation, its equipment components, or the process performance.
Pressure Drop Rates and Gas Flow Technologies
There are several flow measurement technologies available on the market today. Each technology uses a different method to measure a pipe flow rate, but some are known to cause undesirable pressure drops. It is unrecoverable once the pressure decreases. Let's look at some of the most popular flow measurement technologies and their pressure drop scores.
Thermal Mass Flow Meters Have a Negligible Pressure Drop
Other Advantages of Thermal Mass Flow Measuring
There are many advantages of using thermal gas mass flow meters over other flow measurement technologies:
- Air and gas mass flow measurements in standard volumetric units (e.g., SCFM or NM3/H) or mass units (e.g., LBS/M or KG/H)

Airflow Control Within Close Tolerances Saves Money
In drying and coating processes in the pharmaceutical, food and beverage, chemical, petrochemical, and mining sectors, millions of dollars are lost daily - in fluidized beds, rotary drums, flash dryers, kilns, and similar processes. Because of improper air and product feeds, these devices' failure can cause validation problems, causing downtime, re-validation, and loss of both goods and profits. It's vital to control airflow through these devices.
PROBLEM
How can vital processes and devices that need to work within tight tolerances over a broad operating range be supported with continuous air mass flow at a regulated air temperature?
1) Improving Production Efficiency
The off-specification product must be recycled or wasted. This process is too costly, especially in the validated industries. Precise control of airflow and air temperature is essential to maintain high product quality, reduce waste, and increase uptime. The performance of many processes would benefit from measuring the mass flow of process air. Also, limited flow meter turndown often constrains operational flexibility - primarily when requirements cover a wide range of operating conditions.
2) Dealing with Limited Straight Pipe Runs
Airflow meters incorporated into process equipment are often inaccurate due to the short upstream and downstream straight pipe run. The installation of a good straight run can quickly become problematic in tight quarters, so other solutions are needed.
3) Reducing Plugging and Coating
Most process equipment designs do not include relatively dirty exhaust flow measurements, even though they can provide significant operational benefits. They are often not included because exhaust flow meters can become coated and plugged when particulates are present — reducing flow meter accuracy.
Products from Air Monitor solve these issues by enhancing the reliability of your airflow meters by improving their accuracy over a wide range of flow rates, thus improving the process's efficiency, improving the product's consistency, and increasing production rates to reduce fuel spending.
