输油生产中加热炉是主要的耗油设备,单炉平均耗油量10t/d左右,因此,提高炉效即能大大降低油耗。为此,本人根据生产操作经验,介绍一点体会。 1.燃料油温度控制在90℃～110℃为佳。其原因是油温高,粘度低,易分成较小的油珠(直径为2μm),在炉膛中雾化好,火焰为金黄色。在相同的排量、油压、空气温度及火嘴数目下,燃料油的消耗可以降低1t左右,提高炉效2％～4％。 2.燃料油压力最好控制在0.6～0.8MPa之间。其原因是压力大,火焰长,辐射室辐射面积减
Heating furnace oil production is the main fuel-consuming equipment, a single furnace average fuel consumption of about 10t / d, therefore, to improve furnace efficiency that can greatly reduce fuel consumption. To this end, I based on the production operation experience, introduce a little experience. 1. Fuel oil temperature control at 90 ℃ ~ 110 ℃ is better. The reason is the high oil temperature, low viscosity, easily divided into smaller oil droplets (diameter 2μm), good atomization in the furnace, the flame is golden yellow. In the same displacement, oil pressure, air temperature and the number of nozzles, fuel oil consumption can be reduced by about 1t, improve furnace efficiency of 2% to 4%. 2. The best control of fuel oil pressure between 0.6 ~ 0.8MPa. The reason is the pressure, long flame, radiation room radiation area minus
