油田加热炉是油田上重要的加热设备 ,热效率已提高到85 %以上 ,采用的燃烧方式多为负压燃烧。这种常规的稳定燃烧方式使其燃烧强度和换热强度均较低。为了提高加热炉热效率 ,必须加大其换热面积 ,这样 ,促使加热炉炉体尺寸很大 ,单位热负荷和耗钢量大幅度上升 (达 16 .3t/MW) ,由此导致加热炉造价很高 ,使油田工程一次性投资明显增加。同时 ,《大庆油田有限责任公司锅炉压力容器安全管理规定》中已明确规定 :“加热炉应设火焰监控及停电、停泵、停输的情况下自动切断燃料供给的安全联锁保护装置。”目前 ,大庆油田使用的大多数负压炉尚未达到此要求。因此 ,火筒炉向高效节能、造价低、自动控制水平高、安全可靠的趋势发展势在必行 Oilfield heating furnace is an important heating equipment on the oilfield, the thermal efficiency has been increased to more than 85%, the combustion method used are mostly negative pressure combustion. This conventional method of stable combustion makes both its combustion and heat transfer strengths low. In order to improve the thermal efficiency of the heating furnace, it is necessary to increase the heat transfer area, so that the heating furnace furnace to promote the size of a large unit heat load and consumption of steel increased significantly (up 16.3t / MW), which led to the furnace cost High, so that a one-time investment in oilfield projects increased significantly. At the same time, “Daqing Oilfield Co., Ltd. Boiler and Pressure Vessel Safety Management Regulations” has made it clear: “Heating furnace should be set flame monitoring and power outages, stop pump, stop the case of fuel supply automatically cut off the safety interlock protection device.” At present, most of the negative pressure furnaces used in Daqing Oilfield have not yet reached this requirement. Therefore, the fire furnace to high-efficiency energy-saving, low cost, high level of automatic control, safe and reliable trend of development is imperative
