УСТРОЙСТВО И СПОСОБ ДЛЯ КАЛЬЦИНАЦИИ ГИПСА
[Object] Fluidization of a deposit of raw gypsum in a calciner is so improved as to prevent uneven calcination of calcined gypsum from occurring and reduce a fuel consumption of the calciner. [Solution] An apparatus for calcination of gypsum includes a gypsum calciner (1, 3-7) having an interior wall surface with a circular or annular configuration as seen in its plan view, and a tubular combustor (2) positioned at a center part of a body of the calciner. The raw gypsum (M) in the calciner is calcined or dehydrated by a high temperature gas spouting flow (Hg) ejected from a lower portion of the combustor. The calciner has a stationary-vane-type or movable-vane-type auxiliary device, which circumferentially energizes the raw gypsum in vicinity of the interior wall surface toward a circumferential direction of the calciner, or augments a movement of the raw gypsum therein toward the circumferential direction. The auxiliary device has a plurality of stationary vanes (10) circumferentially arranged in an outer peripheral zone of a lower portion of the combustor and spaced apart from each other at an angular interval, or an agitator (30) extending through a conical or inner circumferential surface defined by the interior wall surface.
