Abstract: A process for preparing mixts. of oxidising and reducing gases contg. determined proportions of oxidised constituents, partic. water vapour, consists of feeding reducing gas through one pipe and oxidising gas through a second pipe, concentric with the first, and buring the mixt. in a combustion chamber. A mixt. of gases contg. a predetermined constant proportion of oxidation product goes out through an exit pipe at a temp. above the dew-point of the mixt. In the case of high rates of flow of the gas mixt., a supplementary gas stream is fed to the outlet pipe, after the combustion chamber. The streams of reducing and oxidising gas consist partic. of hydrogen, and excess oxygen or air, respectively, or a mixt. of H2 and CO2, and oxygen, respectively. Appts. consists of a hollow main portion in stainless steel, with concentric inlets for the first and second gas streams, a combustion chamber in which is an ignition device, and an outlet pipe for the mixt. The process, based on combustion, gives more exact proportions of oxidation product that existing processes, based on satn. with pure water at a specific temp. coressp. to the dew point of the required mixt. or boiling water and diluting the stream with a curent of dry gas. It is simpler and can be used to generate flows of mixts. over a wide range with adequate regularity.
