Abstract

An ethylene cracking furnace is disclosed. The ethylene cracking furnace comprises radiation chambers, convection chambers, quenching boilers, a flue and a blower fan. The convection chambers are disposed on the radiation chambers. The flue and the blower fan are disposed on the convection chambers in sequence. The radiation chambers are provided with radiation coil pipes. The convection chambers are provided with convection coil pipes. The length direction of the convection coil pipes is perpendicular to the arrangement direction of the radiation coil pipes. The ethylene cracking furnace can effectively overcome the problems of the present cracking furnaces, namely limited production capability, long furnace pipe length in the convection section, large-scale equipment, and complex design for a pipe stretching across the convection chambers and the radiation chambers.

Description

technical field [0001] The invention relates to the field of ethylene cracking, in particular to an ethylene cracking furnace. Background technique [0002] Ethylene cracking furnaces are mainly divided into single-hearth box furnaces and double-hearth door-type box furnaces. The single-hearth box-type furnace has only one radiation chamber, and the double-hearth door-type box furnace has two radiation rooms. Both the single-hearth box furnace and the double-hearth door-type box furnace have only one convection chamber, and the extension direction of the convection chamber is in the same direction as the radiation chamber. When the production capacity of the furnace is increased, only the floor space of the cracking furnace can be increased and the equipment needs to be enlarged to adapt to it. Due to the parallel arrangement of the convection chamber and the radiation chamber and the quenching boiler is arranged in the length direction of the convection chamber, the cross-...
