Boiler slag is granular sand or gravel-type substance, of which 15–45% consists of glass, metal, ceramics, rock material, and organic matter.

Development of Heat Recovery System from Steelmaking Slag

The crushed slag is then supplied continuously to the heat recovery plant by a bucket elevator. Heat is exchanged by blowing air into the packed slag in the slag heat recovery chamber from two blowers. Heat recovery is then evaluated by measuring the temperature history of the recovered gas and the pressure drop in the packed bed.Heat recovery in dry granulation of molten blast furnace [email protected]{osti_, title = {Heat recovery in dry granulation of molten blast furnace slag}, author = {Tetsuro, N and Hiroshi, N and Koichi, F and Tsukio, I}, abstractNote = {In a research and development project undertaken jointly between Ishikawajima-Harima Heavy Industries Co. and Sumitomo Metal Industries, Ltd., a process has been developed for granulating molten slag .Dry slag granulation with energy recovery - From inception ...Abstract Paul Wurth has approached the topic of dry slag granulation with a simple but effective method in which steel spheres and liquid slag are mixed to achieve fast cooling of the blast furnace...Precious Metal Refinery ProceduresRecovery of Metals from Mattes and Slags.
