Heat treatment processes for metals represent harsh environments for the measurement of blanket gas constituents. Ambient conditions in the furnaces have high particulate levels, acid gases and other compounds either outgassing or being burned off of the metal components being processed.
Hydrogen gas is used for cooling rotor windings in turbine generators for several reasons. Its extremely low density offers minimal resistance to rotor rotation reducing the energy requirement for same. Furthermore, its excellent thermal conductivity makes it a very efficient carrier of heat away from the generator, where it is cooled and continuously recirculated in a closed loop.
