【摘要】：加热炉是石油化工企业主要生产设备,其在工作过程中需要消耗大量的能源,排放大量的二氧化碳、氮氧化物等有害气体严重破坏和影响生态环境,这就给企业的节能减排、环境保护和效益等工作带来了巨大的压力。因此研究加热炉如何降低能源消耗和减少有害物质的排放,具有重要的意义。本文在详细分析了纳米陶瓷喷涂材料的国内外的发展和应用情况的基础上,对中石化洛阳分公司三联合车间重整炉的辐射受热面进行了RSI纳米陶瓷材料的喷涂改造。通过加热炉在纳米陶瓷喷涂材料使用前后的一系列数据分析和对比可以看出:使用RSI纳米材料后,有效的强化了加热炉的辐射换热,降低了导热热阻,优化了燃烧和传热过程,同时有效的减少了氮氧化物(热力NOx)的排放,增加了基质材料的使用寿命。应用结果表明:RSI纳米陶瓷材料的使用,全面提升加热炉的热效率、生产能力、安全可靠性和改善排放特性,加热炉的燃料气消耗下降明显及热效率有显著提高,从而取得良好的经济效益,达到了预期的目的。
[Abstract]:Heating furnace is the main production equipment in petrochemical enterprises, which needs to consume a lot of energy, emit a large amount of carbon dioxide, nitrogen oxide and other harmful gases seriously damage and affect the ecological environment, which will give enterprises energy saving and emission reduction. Environmental protection and efficiency have brought great pressure. Therefore, it is of great significance to study how to reduce energy consumption and reduce the emission of harmful substances. Based on the detailed analysis of the development and application of nano-ceramic spraying materials at home and abroad, the radiation heating surface of the reforming furnace in the third joint workshop of Luoyang Branch of Sinopec has been modified by spraying the RSI nano-ceramic materials. Through a series of data analysis and comparison of the heating furnace before and after the use of nano-ceramic spraying materials, it can be seen that after using RSI nano-materials, the radiation heat transfer of the furnace is effectively strengthened, the thermal resistance of the furnace is reduced, and the combustion and heat transfer process is optimized. At the same time, the emission of no _ x (thermal no _ x) is reduced effectively, and the service life of the matrix material is increased. The application results show that with the use of RSI nano-ceramic materials, the thermal efficiency, production capacity, safety and reliability of the furnace are improved, and the fuel gas consumption and thermal efficiency of the furnace are obviously decreased. In order to achieve good economic benefits, achieve the desired purpose.
