    摘要: A cracking furnace construction includes a firebox (12) defining a chamber (20) having a high emissivity thermal protective layer (18) disposed on at least part of the refractory walls (17) and/or on process tubes (14) disposed within the chamber (20). The coating contains an inorganic adhesive for metal/alloy tubes or colloidal silica and/or colloidal alumina for refractory walls (17) or ceramic tubes, a filler, and one or more emissivity agents. A method of coating the firebox chamber (20) includes preparing the surface of the tubes/refractory walls (17), preparing the coating, and applying the coating to the surface.
