大型加热炉高等级发展促进高效装运技术进步

Progress of High Efficiency Shipping Technology Promoted from Development of Large Heating Furnace

综述了在炼油化工加热炉大型化高等级发展中,加热炉主要零部件或大模块的高效装运技术。结合33张案例图片总结了对流段模块本体结构的加强、加热炉整体一体化装运和各种零部件装运等三方面工程实践。结构加强具体包括模块局部结构改进、模块整体结构选优,零部件装运具体包括炉管、管板、炉墙、扶梯和烟道等。最后指出了模块吊装受力分析和吊具设计中存在的4个问题及其对策。

In this paper, the technologies for main components in heating furnace and for high efficiently shipping of large module, which appears in the development of large capacity of heating furnace used in petrochemical industry, were summarized. With 33 case photos, three aspects in engineering, including strengthening of the structure in module body, integrity shipping for heating furnace and the shipping of components, were summarized. The strengthening of body structure includes the improvement of local structures in module and the optimization of integral module. The shipping of components includes that of fin tube, tubesheet, panel, ladder and flue gas duct. Finally, four problems existed in the analysis of loads for lifting of module and in the design of lifting tools were illustrated, for which the countermeasures were also demonstrated.
