Description

Special anti-oxidation high-emissivity coating for ethylene cracking furnace
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to an oxidation-release high-emissivity coating special for an ethylene cracking furnace.
Background
The ethylene cracking furnace is used for processing cracking gas and is of the types of double radiation chambers, single radiation chambers and millisecond furnaces. The ethylene cracking furnace is the core equipment of an ethylene production device, and mainly has the functions of processing various raw materials such as natural gas, refinery gas, crude oil, naphtha and the like into cracking gas, providing the cracking gas for other ethylene devices, and finally processing the cracking gas into ethylene, propylene and various byproducts. However, the cracking furnace is the core of the ethylene plant, and is the major energy consumption part of the ethylene plant. In the cracking process, the inner wall of the cracking furnace can generate coking phenomenon, and the gradually accumulated coke can cause pressure drop increase, extra heat transfer resistance and pipe carburization. These can reduce product selectivity, energy efficiency and the operating life of the furnace. The high-emissivity coating is sprayed on the surface of the lining of the radiation section, so that the radiation heat transfer of the furnace lining to the furnace tube is enhanced, and the effect of energy conservation is achieved. However, in the practical application process of the industrial boiler, the phenomena of peeling, cracking and peeling of the coating often occur.
At present, most of high-emissivity coatings are water-based coatings, most of industrial boiler tubes are carbon steel or low-carbon steel tubes, and after the water-based coatings are sprayed on the surfaces of the carbon steel, the surfaces of the carbon steel are inevitably oxidized along with the rise of temperature, so that the bonding force between the coatings and the steel tubes is reduced, and the service life of the coatings is influenced.
