东方红炼油厂近几年原油实际加工能力都在550万吨/年以上,能耗约占原油加工总量的8％。其中工艺加热炉所消耗燃料油(气)又占全部能源消耗1/3。所以提高工艺加热炉热效率是炼油厂节能主要方面。我厂共有工艺加热炉26台,多数为圆筒炉,加热炉总设计热负荷26895万大卡/时,造台实际热负荷只有14000万大卡/时左右,约占设计热负荷的52％,到目前为止,全厂已有14台较大的加热炉分别采用不同方式回收烟气余热,用来加热空气,进一步降低炉子热负荷提高加热炉热效率,节约燃料油。采用烟气余
Dongfanghong refinery in recent years, the actual processing capacity of crude oil at 5.5 million tons / year, energy consumption accounts for about 8% of the total crude oil processing. Among them, the fuel oil (gas) consumed by the process heating furnace accounts for 1/3 of the total energy consumption. Therefore, improving the thermal efficiency of process heating furnace is the main aspects of refinery energy efficiency. I plant a total of 26 process furnaces, most of the cylindrical furnace, heating furnace design total heat load of 268.95 million kcal / hour, the actual heat load Taiwan only 140 million kcal / h or so, accounting for about 52% of the design heat load, So far, the whole plant has 14 large heating furnaces that respectively recover waste heat of flue gas in different ways to heat the air, further reduce the heat load of the furnace, increase the thermal efficiency of the heating furnace, and save fuel oil.
