【摘 要】Described were blast furnace slag waste heat recovery systems based on such technologies from foreign countries as solid particle impingement, mechanical agitation, rotary drum granulation, centrifugal granulation and air quenching etc. and summarized were the current status of the application of blast furnace slag waste heat recovery and treat- ment technologies in China. After the authors have compared the merits and demerits of the same kind technologies both in domestic and abroad, they pointed out that the waste heat recovery system based on the centrifugal granula- tion technology boasts excellent granulation performance and a high heat recovery efficiency etc. On this basis, they believed that it is necessary to further study the operating power consumption, stability, control parameters and slag particle treatment capacity of the system as well as the uniformity of the particle diameters etc. in a hope to realize its commercial applications as soon as possible. Key words: blast furnace slag, granulation, heat transfer,waste heat recovery
