摘　　要：通过分析焦炉荒煤气特性、煤焦油结焦特性,开发上升管换热器技术、不粘涂层技术,为焦炉荒煤气余热回收技术推广提供参考,并对今后荒煤气换热器技术发展方向和荒煤气余热回收工艺提出相关建议。目前,该研发成果已成功地应用于6m焦炉节能示范工程,显热回收利用系统等表现出良好的操作和使用性能,各项运行参数合理,系统运行稳定,解决了蒸发器内壁结焦、积碳和腐蚀等行业普遍存在的技术难题。Through the analysis of coke-oven gas characteristics, coking mechanism,the development of heat exchanger for coke-oven gas sensible heat recovery and anti-coking and non-sticking coating,a reference for promotion using coke-oven gas sensible-heat recovery technology was provided,and some advises about the development of coke-oven gas heat exchanger and the technology of coke-oven gas sensible heat recovery were given.At present, the research achievements was successfully applied to energy saving projects of 6 m coke ovens. The sensible-heat recovery and utilization system shown good operation and usage performance. The operation parameters were reasonable, the system runs steadily, The problems of coking, carbon deposition and corrosion were solved.
