Spectrex Inc. in Cedar Grove, N.J., is introducing the Hydrogen Flame Detector 20/20SH to address the need of a wide range of industrial and commercial facilities that use hydrogen fuel cells, hydrogen gas generators, and hydroxyfuels. Most of the existing optical flame detectors are designed for detection of hydrocarbon flames and are based on the fire’s CO2 emission but cannot detect the hydrogen flames that emit in the water-vapor (H2O) band and have no emission in the CO2 range, company officials say. UV and some UV/IR optical flame detectors that can detect the hydrogen flame have a very limited range. Therefore, this special detector that includes sensors with special filters for the detection of hydrogen’s main combustion product, water vapor, at an extended detection range of 100 feet has been developed. The optical sensors and filters have been carefully selected to ensure the greatest degree of spectral matching to the radiant energy emitted by the hydrogen fire and the lowest degree of matching to non-fire stimuli. This highly advanced detector uses programmable algorithms, which check the ratio and correlation of data received by the optical sensors. The microprocessor design allows for unique field programmability, making the 20/20SH a user-friendly diagnostic and maintenance tool for the high-risk industries. As the hydrogen community moves toward commercialization, the new emerging use of hydrogen for automotive transportation requires special safety measures for the unique refilling stations, storage tanks, and special hydrogen fuel cells handling facilities.
