摘要:以燃料为热源的热处理炉使用面广、造价便宜。将煤气化后作为热处理炉的热源,不仅能满足热处理的工艺要求,达到环境保护的标准,也符合我国的燃料结构。随着与之相适应的各种新的燃烧技术和燃烧设备的不断问世,燃料加热热处理炉以後将会得到迅速地发展。7840
该设计是在所学《传热学》《工程热力学》《燃料与燃烧》等专业课的基础上,查阅大量热处理炉设计资料,对热处理炉炉进行整体设计。该设计为产量为6.5t/h(0号柴油)推钢式热处理炉。
设计内容包括文献综述、热工计算、金属加热计算、炉子主要尺寸确定、炉膛热平衡与燃料消耗量计算、煤气烧嘴的选用、空气换热器设计计算、空气管路阻力损失计算及鼓风机选择、烟道阻力损失及烟囱计算、英文文献翻译等几部分。最后运用CAD对热处理炉本体进行总体绘图。

Design of Fuel Heat Treatment Furnace
Abstract: Use a wide range of heat treatment furnace to heat the fuel, the cost is cheap. After the gas as the heat source of heat treatment furnace, not only to meet the technological requirements of the heat treatment to achieve the standards of environmental protection, but also in line with our fuel mix. Continue to come out with suitable new combustion technology and combustion equipment, fuel heating heat treatment furnace will be rapid development.
This design is based on the Heat Transfer, Engineering Thermo dynamics, Flame Furnace and other course, and referred to a large number of furnace design information for the overall design of the furnace. The production of the continuous slab pusher-type furnace is designed as 115t/h.
The design includes literature review, thermal calculation, metal heating calculation, the determine to the furnace main dimensions, furnace heat balance and fuel consumed, the choice of the gas burner, heat exchanger design and calculation, air lines pressure drop calculation and air blower choice, flue resistance loss and the chimney calculation, the English translation of the literature and others. Finally, the CAD software is used to draw the whole body of the furnace.
