DRY SLAG GRANULATION WITH HEAT RECOVERY*
FEhS Building Materials Institute (Germany) and the University of Leoben (Austria), a new technology based on dry-slag-granulation is being investigated to use air to cool molten slag and to recover the remnant heat energy for heating applications or for the generation of electrical energy. At the same time, the slag product should also

Dry Slag Granulation: A Path to Improving the Safety and
Aug 23, 2016The energy in slag is lost through dumping and water granulation processes, and where slag is sold as a by-product, it is for its chemical content only. Here, dry granulation processes also offer advantages including the production of by-products which hold value in both their chemical content and physical properties and heat recovery.

Dry Granulation of Blast Furnace Slag Steel360
Apr 04, 2019Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag. Atomization is done using a rotary cup air blast atomizer (Fig 1). The particles cool as they travel through the air and are then cooled further in a fluidized bed.

AISTech2018 Dry Slag Granulation The Future Way
Figure 1: Dry Slag Granulation (DSG) Concept Dry slag granulation is based on molten slag atomization using a variable speed rotating cup or dish (see Fig. 1). The slag is fed from the slag runner via a vertical refractory lined pipe directly onto the center of the rotating cup.

Granulation and Heat Recovery from Metallurgical Slags
Dec 09, 2019Dry granulation requires far less cooling water, it is more compact and allows recovery of waste heat/energy from the molten slag. Dry granulation also avoids the emission of H 2 S and SO 2 with steam. The dry slag atomisation by air blasting has been commercialised in recent years and provides some attractive features.
