ETHYLENE CRACKING FURNACE AND THERMALLY-INSULATING COMPOSITE LINING THEREOF

Title:

ETHYLENE CRACKING FURNACE AND THERMALLY-INSULATING COMPOSITE LINING THEREOF

Document Type and Number:

WIPO Patent Application WO/2022/100563

Kind Code:

A1

Abstract:

A thermally-insulating composite lining comprises an upper lining and a lower lining, both of which comprise an inorganic fiber prefabricated layer. The inorganic fiber prefabricated layer can reduce the thermal conductivity coefficient of the lining, thereby reducing heat loss. In addition, since existing inorganic fiber materials are usually not resistant to high temperatures, the thermally-insulating composite lining provided by the present application is provided with a refractory coating on the surface of the inorganic fiber prefabricated layer, so as to prevent the inorganic fiber prefabricated layer from being directly heated; thereby avoiding high temperature damage of the inorganic fiber prefabricated layer, and improving the service life of the thermally-insulating composite lining. The present application further provides an ethylene cracking furnace, comprising any of the foregoing thermally-insulating composite linings.
