Detection of hydrogen fire

Hydrogen flame, like alcohol flame emits little visible radiation but yet emits UV radiation. The capability to visualize hydrogen flames was demonstrated with the hydrogen flame of a gas chromatograph FID detector.
For the demonstration, the valve regulating the hydrogen flow was opened to obtain a flame of 1.5 cm.
The bi-spectral SBUV - Visible image of the hydrogen flame and the gas chromatograph is taken from a distance of 2 m.

Since hydrogen flame is not visible to the human eye there is no sufficiant way to determine if the hazardous fire is present or if a hydrogen fire is about to get out of control.

Remote sensing using SBUV technology enables unequivocally video visualization & detection of hydrogen fire.

SBUV hydrogen flame detection should be implemented as fire hazard preventive procedure of:

• gas cistern ranches
• petroleum refineries
• plants involved in hydrogenation processes
• quality control & safty testing of hydrogen fuel cars
• rocket fuels
• safety at rocket launch pad
• handling accidents involving hydrogen tankers see: FS-World.com article
• research involving hydrogen

This technology could be implemented for regulating new fire safty standards regarding hydrogen gas & flame treatment.
 

Hydrogen is colorless, highly flammable gaseous element. It is the lightest of all gases and the most abundant element in the universe.
Hydrogen is used in the Haber process for the fixation of atmospheric nitrogen, in the production of methanol, and in hydrogenation of fats and oils. It is also important in low-temperature research.
In the car industry, hydrogen-powered fuel cells produce electricity through a chemical reaction between hydrogen and oxygen, and produce no harmful emissions. The hydrogen may be stored as a pressurized gas in onboard fuel tanks. The electricity feeds a storage battery that energizes a vehicle's electric motor.
