Production of acetylene by incomplete combustion of hydrocarbons with oxygen

Claim 1

IN A PROCESS FOR THE PRODUCTION OF ACETYLENE BY INCOMPLETE COMBUSTION OF A PREHEATED HYDROCARBON GAS WITH PREHEATED OXYGEN WHEREIN THE TWO PREHEATED GASES ARE SUPPLIED SEPARATELY THROUGH CONCENTRIC TUBES INTO THE ELONGATED MIXING CHAMBER OF CIRCULAR CROSS-SECTION, THE TWO GASES ARE MIXED IN SAID MIXING CHAMBER ANS DISTRIBUTED THEREFORM BY MEANS OF A PLURALITY OF PARALLEL CHANNELS INTO A COMBUSTION CHAMBER IN WHICH SAID GASES REACT WITH FLAME FORMATION, AND THE GASEOUS REACTION PRODUCTS ARE RAPIDLY COOLED BY SPRAYING WITH WATER, THE IMPROVEMENT FOR AVOIDING FORMATION OF A STATIONERY FLAME IN SAID MIXING CHAMBER WHICH COMPRISES: MAINTAINING THE MEANS SPEED OF FLOW OF THE TWO GASES AT THEIR JUNCTION POINT IN THE MIXING CHAMBER AT NOT LESS THAN 150 METERS PER SECOND, THE SPEED OF FLOW OF THE PREHEATED HYDROCARBON GAS BEING GREATER THAN THAT OF THE PREHEATED OXYGEN AT SAID JUNCTION POINT, AT A HYDROCARBON GAS THROUGHPUT OF MORE THAN 1000 NORMAL CUBIC METERS PER HOUR AND PREHEATING TEMPERATURES ABOVE 500*C.
