Beschreibung
Zusammenfassung:	The utility model relates to the technical field of crude oil cracking, in particular to a cracking furnace with an auxiliary combustion chamber, which comprises the auxiliary combustion chamber arranged on one side of the cracking furnace. One end of the auxiliary feeding pipe is connected with the auxiliary combustion chamber, and the other end of the auxiliary feeding pipe is connected with the bottom of a primary distillation tower, so that crude oil at the bottom of the primary distillation tower is conveyed into the auxiliary combustion chamber to be heated; one end of the auxiliary discharging pipe is connected with the auxiliary combustion chamber, and the other end of the auxiliary discharging pipe is connected with the atmospheric tower, so that the crude oil in the auxiliary combustion chamber is conveyed into the atmospheric tower. One end of the smoke exhaust pipe is connected with the auxiliary combustion chamber, and the other end of the smoke exhaust pipe is connected with the convection secti
