Heating method of double-hearth lime shaft kiln
The invention provides a heating method of a double-hearth lime shaft kiln, and belongs to the technical field of double-hearth lime shaft kilns. The heating method comprises a first heating stage, afirst heat preservation stage, a second heating stage, a second heat preservation stage, a third heating stage, a third heat preservation stage, a fourth heating stage and a fourth heat preservation stage which are sequentially carried out in a direct connection channel of the double-hearth lime shaft kiln, wherein the heating rate of each heating stage is less than or equal to 15 DEG C/h; the heat preservation temperature of the first heat preservation stage is 142.5-157.5 DEG C, the heat preservation temperature of the second heat preservation stage is 285-315 DEG C, the heat preservation temperature of the third heat preservation stage is 570-630 DEG C, and the heat preservation temperature of the fourth heat preservation stage is 855-945 DEG C. The method can effectively avoid the problems of brick burst, damage to the special-shaped bricks of the arch of the direct connection channel, cracking of the furnace wall and the like.
本申请提供一种双膛石灰竖窑的烘窑方法，属于双膛石灰竖窑技术领域。烘窑方法，包括在双膛石灰竖窑的直联通道依次进行的第一升温阶段、第一保温阶段、第二升温阶段、第二保温阶段、第三升温阶段、第三保温阶段、第四升温阶段以及第四保温阶段。其中，每个升温阶段的升温速率均≤15℃/h；第一保温阶段的保温温度为142.5～157.5℃，第二保温阶段的保温温度为285～315℃，第三保温阶段的保温温度为570～630℃，第四保温阶段的保温温度为855～945℃。该方法能有效避免出现砖的爆裂、损伤直联通道拱门异形砖、炉墙开裂等问题。
