Novel Study for Energy Recovery from the Cooling–Solidification Stage of Synthetic Slag Manufacturing: Estimation of the Potential Energy Recovery
Description
Herein, a novel method for energy recovery from molten synthetic slags is analyzed. In this
work, the potential energy that could be recovered from the production of synthetic slag is estimated
by means of an integrated experimental–theoretical study. The energy to be recovered comes from the
cooling–solidification stage of the synthetic slag manufacturing. Traditionally, the solidification stage
has been carried out through quick cooling with water, which does not allow the energy recovery.
In this paper, a novel cooling method based on metal spheres is presented, which allows the energy
recovery from the molten slags. Two points present novelty in this work: (1) the method for measuring
the metal spheres temperature (2) and the estimation of the energy that could be recovered from these
systems in slag manufacturing. The results forecasted that the temperature achieved by the metal
spheres was in the range of 295–410 ◦C in the center and 302–482 ◦C on the surface. Furthermore,
we estimated that 325–550 kJ/kg of molten material could be recovered, of which 15% of the energy
consumption is in the synthetic slag manufacturing process. Overall, the results obtained confirmed
the potential of our proposal for energy recovery from the cooling–solidification stage of synthetic
slag manufacturing.
