针对某炼油厂延迟焦化加热炉运行周期逐渐缩短的情况，对影响加热炉运行周期的原料性质、温度、负荷和操作调整等因素进行了分析，认为原料性质变化、较大的流量波动、超负荷生产、换热终温波动频繁和操作中参数调整幅度过大等均可加速加热炉结焦速率，缩短装置运行周期。结合焦化装置生产实际情况，提出了增设原料缓冲罐和混合器、加强对冷渣油性质分析、恒定换热终温、控制生产负荷和平稳操作等整改措施。措施实施后，可以有效地减缓加热炉结焦速率，延长加热炉运行周期，经济效益提高约609万元∕a。

Heating furnace is the core of the coking unit,which plays a vital role in production. In view of the gradually shortened coking furnace operation cycle,the influence factors of feed property, furnace temperature,operation load,terminal temperature fluctuations of the heat exchanger and heat﹣ing condition adj ustment range were analyzed. It is concluded that all the above mentioned factors can significantly affect the furnace cycle. Based on the discussion,some improvement measures are pro﹣posed,like the adding material buffer tanks and mixers,strengthening the cold slag property analysis, constanting the terminal temperature,controlling the production load and smoothing the operation. Af﹣ter the implementation of above measures,the rate of coke formation effectively slows down and the fur﹣nace operation cycle is prolonged. The economic benefits of about 6. 09 million Yuan per year are real﹣ized.
