我国烧结工序能耗占钢铁工业总能耗的12%,蕴含着巨大的余热回收潜力。目前,大中型烧结机采用带式冷却机或环形冷却机冷却。在显热回收与利用上存在漏风率高(25%~60%),风量大,热废气品质低等弊端。回收热量约占烧结矿总热的约23%,国内余热发电6~18kW h/t烧结矿。部分小型烧结机没有余热回收设施。基于此,北京中冶设备研究设计总院有限公司借鉴干熄焦炉结构与工艺,同时参考炼铁高炉等结构形式,提出了烧结矿竖式逆流余热回收系
China’s sintering process energy consumption accounts for 12% of the total energy consumption of the steel industry, contains a huge potential for waste heat recovery. At present, large and medium-sized sinkers use belt coolers or ring coolers to cool. In the sensible heat recovery and utilization there is a high rate of air leakage (25% to 60%), large air volume, hot exhaust gas quality and other shortcomings. Heat recovery accounts for about 23% of the total heat of sinter, domestic waste heat power generation 6 ~ 18kW h / t sinter. Some small sintering machine no waste heat recovery facilities. Based on this, Beijing Metallurgical Equipment Design and Research Institute Co., Ltd. draws on the CDQ furnace structure and technology, at the same time, with reference to the structure of iron blast furnace and other structures, puts forward the sinter vertical counterflow heat recovery system
