Abstract

Modification of hydrocarbon cracking furnaces, which have radiant and convection zones and which are secured by frames, involves combining at least two existing furnaces to form a single structure by: (a) disassembling the convection zones of the furnaces and extending the radiant zones to the height of the existing frames; (b) extending the frames into or above the interspace between the original furnaces by means of an additional connecting frame; and (c) incorporating the convection zones of the furnaces in this additional frame.
