Abstract
Equipment for producing ethylene and/or acetylene from hydrocarbons, including the reaction chamber (13), burner (11), common or separate fuel gas inlets (12) and oxygen inlets (18), preheating tubes (14), a gas distributor (15), cracking gas inlets (16), and a reaction product outlet (17); the gas distributor (15), which has multiple gas inlets and gas outlets, is arranged on the cross section of the reaction chamber (13), where the gas inlet is connected to the cracking gas inlet (16), and the gas outlet is connected to the preheating tube (14). The cracking gas is uniformly distributed through the gas distributor (15) and passed through the preheating tubes (14), which are hollow tubes; the opening at the other end of the hollow tube is close to or inserted into the combustion area of the gaseous fuel and oxygen.
