METHOD FOR PRODUCING SLAG GRANULATE AND FOR RECUPERATING HEAT FROM LIQUID MELTS

摘要

In the method according to the invention for producing slag granulate and for recuperating heat from liquid melts, the liquid melt is firstly quenched and granulated using a liquid cooling medium and subsequently cooled further by means of a gaseous cooling medium, wherein at least the heat of the heated gaseous cooling medium is recuperated. The quenching and granulation of the melt is realized here by the impetus of the liquid cooling medium as it makes direct contact with the melt. Furthermore, only such an amount of liquid cooling medium is used to quench the melt that a vitreous solidification of the melt in the granulate only just occurs.
