Flue Gas Analysis in Industrial Food Ovens and Dryers

Flue gas analysis helps verify combustion efficiency, detect incomplete burning, measure pollutant levels for regulatory compliance, and optimize fuel-to-air ratios to reduce energy costs.

Ideal readings vary by fuel type and application, but typically oxygen levels range 3-8%, CO levels below 400ppm, and moisture content depends on process requirements and EPA limits.

Industrial flue gas analyzers like MAC Instruments' moisture analyzers use solid-state humidity sensors and electronic combustion analyzers to measure moisture, oxygen, CO, CO2, and temperature in exhaust gases.

MAC's patented solid-state sensors measure water vapor pressure directly without wet bulbs or optics, providing accurate readings up to 2400°F in ovens, dryers, and combustion exhaust streams.

Response times vary by model: MAC155 reaches 90% of final value in 60 seconds, while MAC125 and MAC116 respond within 120 seconds for real-time process control.

The MAC155 features built-in daily 2-point in-situ calibration, while other models should be calibrated quarterly or per EPA requirements for continuous emission monitoring systems.
