为实现焦炉加热系统的弥散燃烧，有效降低NOx的排放，以JN-60型焦炉为研究对象，基于焦炉烟气外循环、煤气低氮燃烧的思路，进行烟气外循环系统“焦炉立火道燃烧试验装置”的研制任务，各项参数指标达到预期目标。

In order to realize the dispersion combustion of the coke oven heating system and effectively reduce the emission of NOx, taking JN-60 coke oven as the research object and based on the idea of external circulation of coke oven flue gas and low NOx combustion, the development task of "the combustion test bed of coke oven heating flue " for external circulation of flue gas system was carried out, and all parameters and indexes reached the expected target.
