Abstract: Thermal efficiency of cracking furnace in ethylene plant is an important parameter to measure the operation of cracking furnace. It is directly related to the energy consumption of ethylene plant. This paper introduces the present situation and influencing factors of thermal efficiency of cracking furnace in Tianjin 0.2 MTA ethylene plant. It proposes that the main way to improve the thermal efficiency is the effective utilization of heat in radiation and convection section of the cracking furnace. The paper expounds the methods and countermeasures for improving thermal efficiency of the cracking furnace from such aspects as improving fuel utilization rate, lowering exhaust gas temperature, optimizing operation and management. Meanwhile, it explicates the measures that need to be improved in future.

Key words: cracking furnace, thermal efficiency, flue gas heat loss, oxygen content in flue gas, exhaust gas temperature
