- 摘要:
油田加热炉是石油行业重要的耗能设备,其节能措施和成效一直是热工界关注的焦点。以主要耗能设备加热炉为研究对象，并对其建立分析模型,结合损计算公式对加热炉损及损系数进行分析,并对加热炉效率的影响因素进行研究,确定影响加热炉损系数的因素为热负荷率、排烟温度和过量空气系数。以中国东部某典型转油站为例,通过分析加热炉工作原理、内部结构及生产运行参数,采用正交实验法分析出影响加热炉反平衡效率的主要因素为热负荷率，次要因素为过量空气系数,排烟温度影响最小。在此基础上提出了加热炉改造的几个关键点,以有效提高效率,保证经济效益。
The heating furnace in oilfield is an important energy consuming equipment in the petroleum industry, and its energy-saving measures and effects have always been the focus of the thermal industry.In this paper, the heating furnace is taken as the main research object, and an exergy analysis model of the main energy consuming equipment is established.Combined with the exergy loss calculation formula, the exergy loss and exergy loss coefficient of the heating furnace is analyzed,and the influencing factors of the efficiency of the heating furnace are studied.The influencing factors of the exergy loss coefficient of the heating furnace are determined as the heating load rate, exhaust gas temperature and excess air coefficient.Taking a typical oil transfer station in eastern China as an example,we have analyzed the working principle, internal structure and production operation parameters of the heating furnace.The orthogonal experiment method is adopted to determine the heating load rate as the main influencing factor on the counterbalance efficiency of the heating furnace, the excess air coefficient as the secondary influencing factor,and the exhaust gas temperature as the least influencing factor.On this basis, several key points of heating furnace transformation are put forward to improve the exergy efficiency effectively and ensure economic benefits.
