    Abstract: This invention relates to a process for producing cement or cement substitutes on the basis of carbon-containing compounds with a carbon content of more than 10 wt-%, wherein the carbon-containing compounds are burnt in a furnace at a temperature of 600 to 900°C, and wherein beside the carbon-containing compounds at least one additional, inert and/or low-heating-value material, which already before or after a thermal treatment has cement properties, is introduced into the furnace and calcined.

    Abstract: The production of calcined clay is effected by using a plant known per se for producing cement by the dry or semiwet process, with a precalciner (1), for instance comprising at least one preheating line of series-connected preheating stages (2), such as cyclone preheaters or grate preheaters, and a rotary kiln or roaster (3). In accordance with the invention, the rotary kiln or roaster (3) for generating heating gas is utilized as combustion chamber (31), replaced by a combustion chamber (3') and/or completed by an additional combustion chamber.

    Abstract: In the heat treatment of fine-grained mineral solids, in particular for calcining clay or gypsum, the solids are passed through a flash reactor (5), in which they are contacted with hot gases at a temperature of 450 to 1500°C, and subsequently they are passed through a residence time reactor (7) at a temperature of 550 to 800°C, from which they are withdrawn after a residence time of 1 to 600 minutes and possibly supplied to a further treatment stage.
