Tubular ethylene cracking furnace TOPICN13013
Tubular ethylene cracking furnace is the main way to produce ethylene in China. The ethylene cracking furnace includes burner, radiant section, Convection Section and quench system, and high pressure steam system. The cracking furnace tube is used in the radiation section, also called Radiant Section Furnace Tube.
Although operating at relatively low pressure, the radiant coils in an ethylene furnace operate under extremely severe conditions of temperature and stress. In order to achieve the required process temperature, the outside temperature can be between 950 and 1100oC depending on the degree of coking produced on the inner surface. In addition the tube temperature must be reduced for de-coking, sometimes in a period of every 30 days, creating additional stress from the inflexible coke layer which may involve stretching and bulging. Carburisation of the tubes causes progressive embrittlement over time eventually reducing the life of the tubes.
