针对国内工业炉窑能源结构不合理、效率低、污染严重的现状,结合煤高温气化和高温贫氧燃烧技术的特性,将2项技术有机地结合,开发研制了1套煤高温空气气化与高温贫氧燃烧一体化实验系统。该系统具有大幅度节能;燃气热值提高、燃料利用范围扩大;NOx排放量低、环境污染小;过剩空气系数低;结构简单、紧凑,系统综合热效率高,经济性好;炉温均匀分布,换热效率提高;采用炉外冷循环,易获得贫氧条件等特点。系统的研制将为中国工业炉窑的燃煤技术改造、系统节能和国家环境保护开辟一条新路。

Aiming at the current situation and existing problems of industrial furnace in China and combining the merits of the high temperature gasification and the high temperature and low oxygen air combustion for coal, the experimental system on the integration of the high temperature gasification and the high temperature and low oxygen air combustion are developed and the technological process and the characteristics of the system are analyzed. The system has advantages of great energy saving, high caloric value, low NO42pollution, low excess air ratio, equipment downsizing, high thermal efficiency, uniform oven temperature distribution and so on. The development of this system will open a new way for coal-fired technological transformation, energy saving and environmental protection of the industrial furnace in China.
