Process Improvement

Auburn's monitoring equipment improves process efficiency for higher financial return

Provides reliable Flow or No Flow indications for many process applications such as:
• Powder injection
• Pneumatic conveying
• Screw conveyor flow, etc.
Simple, durable, probe design is superior to conventional mechanical or optical flow detectors

General Process Applications
The conveying or transporting of dry particulate for manufacturing processes requires a reliable means to verify flow/no-flow (blockage). Auburn loss-of-flow detectors, which are closely related to the dust emission bag rupture detectors (onset of particulate flow) are in use for a wide variety of flow applications in a number of industries. Typical examples include: monitoring for blockages or for no-flow detection in pneumatic conveying/material handling systems, to monitor screw feeders and or fan operation; monitoring the velocity of particles to reduce product breakage for cereal manufacturers; monitoring pulverized coal injection to boilers to balance the flow evenly from the multiple nozzles (in beta tests),

Also, in very recent developments, large scale power utilities are required to reduce or eliminate SO2 and mercury emissions and must verify the flow of 1) lime and 2) activated carbon injection into the exhaust gas flow stream, agents injected to react with those pollutants, and subsequently collected by fabric filter collectors for disposal. These applications, a hybrid of a process control/compliance application are particularly appropriate for triboelectric technology.

Solid Fuel Injection Measurement for Energy Efficiency
Controlling a modern boiler, furnace or kiln at, or near, maximum efficiency is an extraordinarily complex problem. Numerous parameters need to be monitored and controlled. Moreover, when the fuel is pulverized coal, the monitoring of fuel feeding rate and consistency remains a challenge.

Traditional instruments cannot monitor the gas-solid two phase flow in real time with enough accuracy, robustness and cost-benefit ratios. Inefficient fuel feed monitoring further complicates the ability to optimize boiler/furnace performance. Excess fuel flow is ultimately wasteful, and unnecessary additional air flow will dissipate valuable generated heat, and both cases will produce excessive emission. Avoiding these situations with more comprehensive control technology will save energy and reduce pollution.
