Overview: Ethylene cracking furnace is the core equipment of ethylene production plant. Its main function is to process raw materials such as natural gas, refinery gas, crude oil and naphtha into cracked gas, and supply to other ethylene plants, and finally process into ethylene, propylene and various by-products.
Process flow:
1. Production capacity and reserve coefficient of furnace
2. Single furnace production capacity
3. Operation cycle of cracking furnace
4. Flexibility of raw materials
5. Raw material consumption quota
6. Operating flexibility of cracking furnace
① Operating flexibility of the burner
② Furnace temperature and furnace tube temperature
③ Fluid pressure drop in furnace tube
④ Residence time
1. Heat intensity of furnace tube in radiation section
2. The heat load ratio of the furnace to the radiation section/convection section
3. Bottom heating and side wall heating ratio
4. Fuel consumption quota
5. Exhaust temperature
6. Heat loss of cracking furnace
7. Cracking furnace thermal efficiency
1, the furnace tube configuration using short residence time, high selectivity of one-way or two-way furnace tube.
2, the number of furnace tube groups is increasing, and the production capacity of single furnace is constantly improving.
3. Appropriately reduce the proportion of side heating, reduce the number of burners, reduce investment, and facilitate maintenance.
4, in order to shorten the length of the radiation section, in the large cracking furnace, the structure of double radiation section and single convection section is used.
5. According to different furnace tube configurations, different new waste heat boilers are used to fully recover heat.
6. Continuously improve the control level of cracking furnace and extend the operating cycle of cracking furnace.
