胜利炼油厂采用新技术节能,取得了明显效果。这个厂的北常减压装置常压加热炉为圆筒型,有效热负荷为138160千焦/小时,燃料油耗量约在38吨/日,燃料气280立方米,炉子的热效率为78%。为了提高加热炉的热效率,降低能耗,胜利炼油厂于1987年应用微机控制后,使烟道烟气中的含氧量得到了控制,达到2～3%;炉压控制在-2～0mmH2O;减小了过剩空气系数,平均达到1.13。热效率提高到了80%左右。每天节 Shengli refinery using new energy-saving technology and achieved remarkable results. The atmospheric pressure heating furnace of this plant is a cylindrical type with an effective thermal load of 138,160 kJ / h, a fuel oil consumption of about 38 tons / day, a fuel gas of 280 cubic meters and a furnace thermal efficiency of 78%. In order to improve the thermal efficiency of the furnace, reduce energy consumption, Shengli Refinery in 1987 by computer control, the flue gas oxygen content has been controlled, reaching 2 to 3%; furnace pressure control in the -2 ~ 0mmH2O ; Reduce the excess air coefficient, an average of 1.13. Thermal efficiency increased to about 80%. Every day
