一种球团竖炉用换热器的开发应用

THE DEVELOPMENT AND APPLICATION OF A NEW TYPE HEAT EXCHANGER USING SHAFT FURNACE’S HOT EXHAUSTED GAS TO PREHEAT AIR AND COAL GAS

介绍了一种用竖炉冷却风预热空气和煤气的新型换热器 ,经实践证明 ,不仅节省能源 ,而且还可以提高球团矿的质量 ,减少竖炉的操作维护费用 。

This paper shows a new type heat exchanger,which can use shaft furnace's hot exhausted gas to preheat air and coal gas.The practice has proved that it not only can save energy,but can improve the quality of globular mine and reduce the expense of operation and maintenance of the shaft furnace.It can be widely used in iron & steel corporations.
