Flue gas analyser

The Panametrics OxyTrak 390 flue gas analyser measures unburned oxygen levels in dirty, aggressive combustion applications and uses information to adjust burner air supply for maximum combustion efficiency and safety.

Ideally, burners should mix a precise ratio of air and fuel and the fuel should burn to yield only heat, water vapour and carbon dioxide. In reality, burners age, mixing is imperfect, fuel calorific values vary, firing rates change and the weather changes. Any of these factors can change the amount of air required for safe and efficient combustion of fuel. Accurate flue gas analysis helps optimise the air/fuel ratio.

Typical applications include boilers (all fuels and types, including marine, recovery and utility), furnaces (all fuels and types, including heat treating, glass and process), rotary kilns (ore reduction, cement, alumina processing and others) and incinerators (industrial, municipal and hazardous waste).

The instrument features ex-situ diffusion/convection loop design for measurement accuracy, corrosion-resistant construction, up to 1900 °C temperature rating and automatic calibration and verification.

An optional sensor is also available to measure CO, H2 and other combustibles.
