Reforming furnace equipped with lances for straightening the flames and method for straightening the flames.

摘要

The invention relates to a furnace for carrying out an endothermic process comprising tubes containing catalyst for converting a feed gas, in which the tubes are positioned in rows in the furnace, in which burners called internal burners are mounted in rows. between the rows of tubes and burners called external burners are mounted between the walls of the furnace parallel to the rows of tubes and the rows of adjacent tubes forming rows of so-called external tubes, which furnace is provided with lances installed near the external burners which are suitable for injecting gaseous fluids interfering with the combustion gas streams issuing from said burners. The invention also relates to a method for rectifying the flames emitted in said furnace by the external burners. The direction of the jet of the combustion products emitted by the burners of the external rows is corrected by the injection at the level of the external burners - via lances installed near the burners - of gaseous fluids interfering with the currents of combustion gases coming from said burners. external, so as to straighten the flames.
