ジャーナル フリーStudies were made to investigate DTA curves of the products obtained by mixing hemihydrate gypsum and EDTA (4H and 2Na) in water. The DTA curves of the products were analysed from the position and area changed by dehydration.
The products extremely showed simple curves consisting of endothermic peaks by dehydration of gypsum (120°C-220°C) and exothermic peaks of EDTA metalic complex salt (300°C-450°C). Figure of the curves varied according to mixing conditions.
The peak-area and peak position gave by dehydration of the products was approximately similar with the exception of gypsum containing calcium hydroxide.抄録全体を表示PDF形式でダウンロード (369K) -

ジャーナル フリーConcerning to the calcination of limestone by fluidized bed, 6 T/D new type furnace designed due to the heat balance and the basic study of fluidization was operated.
Characteristics of this furnace are as follows ;
(1) The preheating zone and the cooling zone of moving bed are plated respectively above and below the calcinating zone of fluidized bed.
(2) Between the calcinating zone and cooling, the thermal maturing zone is placed. (3) The fuel is divided and burned separately in the calcinating fluidized bed and out. (4) Size 2.5-10 mm of limestone is used as raw material. (5) The fluidized bed is spouted bed type.
The state of operation were good on the whole. The content of CO2 remained in calcined lime is 0.2-0.3%, the heating value of fuel per 1 t calcined lime is 1, 700, 000 kcal, and the yield of calcined lime is almost 100%.抄録全体を表示PDF形式でダウンロード (897K) -
