在炼化企业中,加热炉是耗能大户,是节能减排的关键设备。某千万吨炼油项目总体设计阶段的一些主要装置燃料消耗占装置总能耗约70%以上,加热炉设计采取节能措施对降低装置总能耗影响非常大。加热炉排烟损失在加热炉的热损失中占有较大的比例,当加热炉效率达90%以上时,排烟损失占总损失约70%~80%,应当把降低排烟温度作为第一位加热炉节能措施。
In the refining business, heating furnace is energy-hungry, is the key energy-saving equipment. Some 10 million tons of oil refinery project overall design phase of the main unit of fuel consumption accounted for about 70% of the total energy consumption of the unit, furnace design to take energy-saving measures to reduce the total energy consumption of equipment has a very large impact. Heating furnace smoke loss in the furnace heat loss accounts for a large proportion, when the furnace efficiency of more than 90%, the total loss of smoke exhaust loss of about 70% to 80%, should reduce the exhaust gas temperature as the first Bit furnace energy saving measures.
