ABSTRACT:
The invention relates to the cooling of red-hot molten blast furnace slag. In this case in order that a substantial proportion of the heat content of the red-hot molten blast furnace slag can be recovered this is introduced together with coal or fuel containing substantially coal into a reactor in which the blast furnace slag is cooled by utilising the heat content of this slag and with the aid of supplied steam to gasify the coal to form a fuel gas, particularly water gas or blue gas containing CO and H.sub.2, which is drawn off separately from the cooled quantity of solids.
