Method and an apparatus for subdivision of and heat recovery from a liquid slag
Patent
·
OSTI ID:5281070
A method is described of sub-dividing and recovering heat from a liquid slag comprising: rolling the liquid slag between at least two cooled briquetting rolls, controlling the temperature of and distance between the rolls so as to obtain a cohesive slag slab with shaped briquettes having a solidified surface layer and a melted central layer, cooling the briquetted slab to a temperature whereat the portions of the shaped slab between the briquettes themselves crack up, whereby the briquettes are automatically separated from each other and recovering heat from the separated briquettes.
