快装式燃油直流热水加热炉

The Development of Packaged Oil-fired Hot Water Heater

目前国内输油管道使用的热水加热炉有相当多是老式加热炉,其结构笨重、技术陈旧、能耗高,正处于更新换代的时期。为此,中国石油天然气华东输油管理局和中国石油天然气管道勘察设计院共同研制出新型高效的快装式燃油直流热水加热炉。该加热炉采用双螺旋管构成的受热面,热水在受热面炉管内强制流动,一次通过全部受热面,加热炉还采用了气动力雾化燃烧器、微正压燃烧、程序控制点火、硅酸铝纤维喷涂成型的轻型炉墙等新技术,它具有轻型快装式结构、技术先进、热效率高、体积小、重量轻、启动快、操作简单、安全可靠性高、使用寿命长等优点。在鲁宁线长清泵站上经过两个冬季的试运行,技术状况良好,各项参数均达到了设计要求。

The packaged oil-fired hot water heater has been developed by Huadong Oil & Gas Transportation Administration Bureau and Oil & Gas Pipeline Survey and Design Institute of China. This new heater overcomes some shortcomings, such as cumber structure, backward technology and high energy consumption existed in the old-type heaters. The heater uses the double spiral tubes as its heated surf ace, which allows the hot water in the tube to flow to pass through the overall surface. Some new technologies and materials have been adopted for the new heater,such as pneumatic atomizing burner,micro-positive pressure burning , program-controlled start-up and lightweight heater wall fabricated with alumina silicate fibre. The heater has many advantages of high thermal efficiency,pet volume,light weight,fast start-up,simple operation, high safety and reliability and a long service life. Two winters' preliminary operation in Changqing pump station in LuNing pipeline shows that the technological parameters meets the requirements of the design.
