Abstract
The invention concerns a method for treating iron-and-steel plant sludge comprising adjusting the available CaO content of the sludge so as to obtain an available CaO content between 3% and 8% based on the sludge weight, adding a carbon-containing fuel, introducing the sludge onto one of the upper stages of a multistage furnace, heating the multistage furnace, gradually transferring the sludge onto the lower stages, and adjusting the temperature of the exhaust gases of the multistage furnace to at least 500°С and that of the treated sludge at the output of the multistage furnace to a temperature ranging between 700°С and 800°С.
