Calcination method of limestone with granularity of 30-90mm
The invention discloses a calcining method of limestone with the granularity of 30-90mm. The method comprises the following steps: adjusting wheat kiln control parameters, ensuring pressure balance of a preheating zone, a calcining zone and a cooling zone, adjusting the opening degree of a cold air butterfly valve, increasing the volume of cooling air, improving the pressure of the cooling air, and ensuring that the cooling air uniformly enters a combustion chamber and a non-combustion chamber; for limestone with fixed organizational structure and chemical components, the decomposition temperature condition is adjusted by combustion air, the combustion air coefficient is adjusted, the waste gas temperature is increased, the channel temperature is reduced, reasonable temperature gradient distribution is ensured, the activity reaches the maximum value, and the virtuous cycle of calcination is promoted.
本发明公开了一种30～90mm粒度石灰石的煅烧方法，通过对麦窑控制参数作出调整，保证预热带、煅烧带、冷却带压力平衡，调节冷风蝶阀开度，加大冷却风风量，提高冷却风压力，保证冷却风均匀进入燃烧膛和非燃烧膛；对于组织结构和化学成分固定的石灰石来说，分解的温度条件是燃烧风来进行调整的，调节燃烧风系数，提高废气温度，降低通道温度，保证合理的温度梯度分布，使活性度达到最大值，促使煅烧良性循环。
