东方红炼油厂对24台加热炉的热效率进行了普查,总结出以下几点经验和体会:1.对现有的加热炉,不上其他措施,调节好“三门一板”,搞好堵漏工作,把热效率提高到70～75%是完全可能的。2.为了降低过剩空气系数,在保证足够备用的前提下,砍掉多余的火嘴。3.加热炉加隔声风罩,即减少噪声,又减少空气漏入。4.为了降低烟气出口温度,应推广伸 Dongfanghong refinery on the 24 heating furnace thermal efficiency conducted a survey, summed up the following experience and experience: 1 on the existing furnace, no other measures to regulate the “three-door” and improve the block Leak work, the thermal efficiency increased to 70 ~ 75% is entirely possible. 2. In order to reduce the excess air coefficient, cut off the extra nozzle under the premise of ensuring enough spare. 3. Furnace plus noise hood, which reduces noise, but also reduce air leakage. 4. In order to reduce the flue gas outlet temperature should be extended
