1.加热炉炉门启闭机构设计的重要性 襄樊输油公司所用的方箱式加热炉,原设计两个喷嘴对原油直接加热。因输油工艺的不断改进,而改用一个喷嘴,炉壁上就闲置一个喷嘴开孔。这一开孔会漏进大量空气,增加散热损失,使过剩空气系数增大。这样不仅降低了燃烧温度,使炉效降低,而且还加快了炉管在高温下的氧化速度。
1. The importance of heating furnace door opening and closing mechanism design Xiangfan oil company used square box furnace, the original design of the two nozzles on the direct heating of crude oil. Due to the continuous improvement of the oil transportation process, a nozzle is used instead of a nozzle opening on the furnace wall. This hole will leak into a lot of air, increase heat loss, the excess air coefficient increases. This not only reduces the combustion temperature, so that the furnace efficiency is reduced, but also speed up the furnace tube at high temperature oxidation rate.
