Abstract
A system is provided for monitoring the levels of combustible gas in a gas stream. The system includes means for controlling the relative humidity of the gas stream and maintain a humidity level in the performance range of combustible gas sensors. A number of methods are illustrated for achieving the humidity control including secondary phase separations and the adjusting of the gas stream temperature.
Claims2
