A two-sensor temperature monitoring system designed to continuously measure true load temperatures in reheat furnace applications especially in the challenging heating sections.

Using AMETEK Land’s leading-edge infrared sensing to measure both furnace load and background temperature, the Furnace Thermometer System (FTS) links to the advanced Landmark Graphic signal processor for a true temperature of the reheat furnace load unaffected by reflections from a hotter background.

Using a two-sensor system that compensates for background radiation temperatures, FTS ensures the corrected true load temperature is continuously displayed by the dedicated signal processor. Monitored correctly, this data can produce significant savings in operational costs.

A dual measurement system measures both the apparent furnace load temperature – which is affected by radiation from the hot background – and the background furnace temperature, enabling the computation of the true load temperature for a highly accurate, real-time result. The selected waveband detectors enable the system to operate in conditions with high furnace background temperatures it also avoids the effects of hot CO2 and H2O in the furnace atmosphere.

FTS is designed for use in gas-fired reheat furnaces in the steel and metals processing industries, and is also suitable for other furnace applications in the hydrocarbon processing and power generation industries.

A TRUE MEASUREMENT
The system measures both the apparent furnace load temperature and the hot background. The signal processor takes both signals and subtracts the effects of reflections from the hot surroundings providing a true load temperature.
