A gas mixer and reactor is provided which is especially suitable as a burner which includes an elongated gas flow chamber with a nozzle arrangement at its inlet end for passing a first gaseous reactant into the interior of the chamber toward the outlet from points uniformly about the inner periphery of the chamber, and an annular nozzle arrangement near the outlet of the gas flow chamber for directing another gaseous reactant or reactants through the outlet of the gas flow chamber and into a thermal reaction chamber which communicates with the outlet of the gas flow chamber.

Gas mixer and reactor

A process for the production of reducing gases and apparatus for use therein is provided. A unique gas mixer and reactor is provided which can be used to effect substoichiometric reactions of gaseous reactants to produce a hydrogen rich gas. The gases which are to be reduced are then admixed with the hydrogen rich gas and the gaseous mixture is passed to a catalytic reactor where the reduction reaction takes place.

Production of reducing gases

A gas mixer and reactor is provided which includes an elongated gas flow chamber with a nozzle arrangement at its inlet end for passing a first gaseous reactant into the interior of the chamber, toward the outlet of the chamber from points uniformly about the inner periphery of the chamber, and an annular nozzle arrangement near the outlet of the gas flow chamber for directing another gaseous reactant, or reactants, through the outlet of the gas flow chamber and into a thermal reaction chamber which communicates with the outlet of the gas flow chamber. In this manner controlled amounts of gaseous reactants may be thoroughly admixed and reacted to produce an atmosphere of desired composition. Atmospheres for kilns having controlled amounts of free hydrogen, carbon monoxide, oxygen, or carbon for example, are produced by burning controlled ratios of fuel, air and in some cases an inert gas, mixed by the reactor.

Production of internal atmospheres for kilns

A gas mixer and reactor is provided which is especially suitable as a burner which includes an elongated gas flow chamber with a nozzle arrangement at its inlet end for passing a first gaseous reactant into the interior of the chamber toward the outlet from points uniformly about the inner periphery of the chamber, and an annular nozzle arrangement near the outlet of the gas flow chamber for directing another gaseous reactant or reactants through the outlet of the gas flow chamber and into a thermal reaction chamber which communicates with the outlet of the gas flow chamber. Also provided are processes utilizing the mixer and in particular a process for converting sulfur containing gas into sulfur.
