Thermal energy recovery from high-temperature blast

Dec 01, 2015· Dry granulation is an attractive alternative to water quenching because of saving energy and reducing water consumption. In many dry granulation technologies, the high-temperature molten slag is atomized to slag particles, and the thermal energy from high-temperature slag particles is recovered by physical and chemical methods.

Some Fundamental Aspects of Dry Slag Granulation Process

Abstract: There is a growing interest in development of a dry slag granulation (DSG) process so as to recover the sensible and latent heats from molten slags and convert iron blast furnace slags into a glassy phase that is a suitable replacement for Portland cement. The combination of waste heat recovery and conversion of slag
