R&D Services: Spectroscopy and Multi-Spectral Imaging for Advanced Furnaces

Two exciting new technologies being developed by Spectral Sciences and thermal solutions vendor Eclipse of Rockford, IL, are in our development pipeline:

Flames used in on-process burners are typically set up manually, giving them an opportunity to drift, and for off-nominal conditions to degrade performance without prompt detection. Our technologies look at the spectrum of the natural radiance from the flame, giving valuable feedback to keep your flame on-spec.

Each uses custom-configured Spectral Sciences combustion analysis software.

Prototype Multi-Spectral Furnace Imager

Air-cooled furnace imaging probe

An air-cooled furnace imaging probe is combined with an affordable multi-wavelength (UV/vis/NIR) spectral camera system and Eclipse burner technology to provide advanced diagnostics and control in industrial furnaces. Our spectral intensity and ratio maps provide views of your furnace that would be invisible to the naked eye, showing the active flame, soot, wall temperatures, and the combustion plume.

Burner-Fitted Spectrometer

The burner-fitted spectrometer is a technology that uses Structured Emission Thermometry (US Patent #6640199) to ascertain and report flame state for rapid, local control of the operating point. The probe is non-intrusively mounted on the burner peep sight, and the light is brought to the readout system using an optical fiber.
