Description
Technical Field
[0001] The utility model relates to the technical field of lime kiln air supply, in particular to a lime kiln with uniform air supply. Background Art
[0002] Lime kiln is an important equipment for making lime. In the process of making lime, air supply equipment is an indispensable condition for the combustion of calcining equipment in the lime kiln production line, because air supply equipment can provide oxygen for combustion. The fuel used in lime kiln is usually coal. In the process of coal combustion, wind is a necessary condition for providing air. The amount of air is also reasonably selected according to the amount of oxygen required by its components during combustion. Lime kilns are generally vertical kilns, and the ventilation inside the vertical kiln is crucial to the lime produced in the kiln.
[0003] If the air volume is too large, the excess air will become a large amount of wasted heat, resulting in unnecessary waste of the lime kiln's production costs. If the air volume is too small, it cannot provide enough oxygen for coal combustion, and the coal cannot be fully burned, resulting in insufficient heat during calcination. Secondly, before the air enters the lime kiln, it needs to be processed to remove floating objects and other debris contained in the air. The air needs to be dried to prevent the wind from bringing more moisture into the kiln. Therefore, a lime kiln with uniform air supply is proposed to address the above problems.
