FIELD: metallurgy.
SUBSTANCE: furnace comprises valving members provided with the cylindrical branch pipes at its inlet and outlet, hopper for limestone, two zones for heating limestone, zone for roasting the limestone, zone for cooling lime, and hopper for lime. The axes of the branch pipes are inclined at an angle of 38-35° to the horizon and are inclined one to the other at an angle of 52-90°. The projections of the extensions of the axes of the branch pipes intersect on the surface of the gas distributing screens at a distance of 0.256-0.375 of the diameter of the zones from their center.
EFFECT: reduced fuel consumption.
