FIELD: construction.
SUBSTANCE: in method for lime production, including crushing of limestone down to fraction of 40-80 mm, its annealing shaft furnace by natural gas combustion products in counterflow mode serially in the technological zones: heating zone with temperature of up to 900°C, zone of direct annealing with temperature of 900-1200°C and cooling zone, in zone of cooling down to temperature of 40-100°C simultaneously with cooling, lime is slaked, for which purpose supplied air is previously moistened by water in amount necessary for complete slaking of lime.
EFFECT: production of slaked lime of higher purity, reduced amount of fuel spent for burning.
