石化加热炉技术进步与节能减排若干问题探讨

Discussion on several issues of technological progress and energysaving and emission reduction of petrochemical furnaces

节能减排、绿色发展是实现经济高质量可持续发展的必然要求。尽管目前新能源呈现迅猛发展的态势,但总的来看其应用场景仍存在亟待突破的局限,化石燃料仍在全球工业能源供给中发挥着重要的作用。石化行业是工业领域的能源消耗和碳排放大户,其中加热炉能源成本占比最大,因此通过加热炉领域技术进步,实现化石燃料高效利用,是推动石化行业节能减排的最有效方式。从加热炉强化辐射传热性能、高效燃烧设备与燃烧技术、燃烧系统控制技术和烟气余热深度利用技术4个方面,对石化企业节能减排能力提升进行了论述。总结了目前研究和技术的现状和特点,并提出应根据不同工艺装置加热炉的特点,因地制宜,应用一种或多种技术组合,以更好地实现节能减排目标。

Energy conservation,emission reduction,and green development are the requirements for high quality and sustainable economic development in China.Despite the rapid development of new energy,there are still limitations in its application scenarios that need to be overcome urgently.Fossil fuels still play an important role in the global industrial energy supply.The petrochemical industry is a major energy consumer and carbon emitter in the industrial sector,with heating furnaces accounting for the largest proportion of operating costs.Therefore,achieving efficient utilization of fossil fuels through technological progress in the heating furnace field is the most effective way to promote energy conservation and emission reduction in the petrochemical industry.This article discusses the improvement of energy conservation and emission reduction capabilities in petrochemical enterprises through technological progress in four aspects:enhancing radiation heat transfer performance of heating furnaces,efficient combustion equipment and combustion technology,combustion system control technology,and deep utilization technology of flue gas waste heat.It also summarizes the current status and characteristics of research and technology,and proposes that one or more technology combinations should be applied according to the characteristics of heating furnaces in different process units,in order to better achieve energy-saving and emission reduction goals.
