Abstract
An improved process for humidifying a gas stream with a precise amount of moisture used in a variety of heat treating processes including annealing, brazing, and sintering of ferrous and non-ferrous metals and alloys, reflow soldering of electronic components, glass-to-metal sealing, chemical processes, chemical vapor deposition of metal oxides, laser processing, fuel cells, etc. The gaseous stream is humidified by introducing a controlled amount of water through a precision metering device and a known and precise flow rate of a gas stream into a gas-liquid contactor, and shearing and vaporizing the water stream in the gas-liquid contactor with the gas stream.
