1.利用热管技术回收烟气余热 河南油田不仅是能源生产单位,而且也是耗能大户。1992年全油田百余台锅炉设备消耗燃料油3.4万吨、燃煤1.3万吨。小型工业锅炉是量大面广的设备,其主要问题是效率低,能耗高,一般排烟温度均为200～300℃,排烟热损失占有相当大的比例,一般为10％～20％,有的甚至更高。不仅直接影响锅炉效率的提高,而且严重威胁着引风机的安全运行,烟气温度远远超过风机铭牌规定的温度(200℃),致使涂漆烤脱,叶轮变形,增加维修费用,缩短使用期限。
1. The use of heat pipe technology to recover waste heat Henan Oilfield is not only an energy production unit, but also energy-hungry. In 1992, over 100 boiler units in the oilfield consumed 34,000 tons of fuel oil and 13,000 tons of coal. Small industrial boilers are large-scale equipment, the main problem is inefficient, high energy consumption, the general exhaust temperature is 200 ~ 300 ℃, exhaust heat losses account for a considerable proportion, usually 10% to 20% , Some even higher. Not only directly affect the boiler efficiency, but also a serious threat to the safe operation of the induced draft fan, the flue gas temperature far exceeds the fan nameplate temperature (200 ℃), resulting in paint roasted off, the impeller deformation, increase maintenance costs, shorten the service life .
