Claim:
1. A continuous process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, comprising: separately heating in preheaters a first input stream comprising one or more hydrocarbons and a second input stream comprising oxygen, mixing in a mixing unit the first and second input streams in a ratio of mass flow of the second to first input stream corresponding to an oxygen ratio of less than or equal to 0.31, wherein the oxygen ratio is the amount of oxygen present in the second input stream to the amount of oxygen which is needed stoichiometrically for full combustion of one or more hydrocarbons in the first input stream, supplying said mixture of the first and second streams via a burner block to a combustion chamber configured for partial oxidation of the one or more hydrocarbons, thus obtaining a first cracking gas stream I cooling in a prequench said first cracking gas stream I removing in a solid-gas separation apparatus 50 to 90% of the solids present in the second cracking gas stream II cooling in a total quench the third cracking gas stream III scrubbing in one or more scrubbing apparatuses the fourth cracking gas stream IV combining process water streams I recycling the combined process water stream IV cooling with a re-cooling device cleaned process water stream VII
