FEGT Measurements

CleanAir manufactures and utilizes high velocity thermocouple (HVT) probes to measure furnace exit gas temperatures (FEGT) and species concentrations.   The probes have an integrated sampling tube that allows an analyzer to draw a gas sample from the furnace to analyze the gas (e.g. O2, CO, NOx).   A water-cooled jacket protects and cools the probe, while quick connect couplings allows for fast and easy attachment of air and water to standard industrial connections.

The water-cooled HVT probe can be used to map the furnace exit plane of a utility or industrial boiler.   Once a traverse of the furnace has been completed, the results can be plotted in order to diagnose operational problems such as air in-leakage, secondary airflow and/or fuel imbalances.
