Calcining process analysis of lime rotary kiln

Lime rotary kiln is the main equipment for calcining limestone. Due to the very high demand for limestone, it can only be used after it is processed to make greater use value. The lime rotary kiln has a lot of advantages in the processing of the ore, has large production capacity, high work efficiency, strong energy saving and environmental protection, and good running stability. This article will analyze the calcining process of lime rotary kiln in detail: First of all, the relationship among preheating, calcining, and cooling are mutual influences and mutual constraints. While the material is preheated in the preheater, a certain percentage of the decomposition rate is required, which is the need for the active lime product to be calcined in the rotary kiln. The effective decomposition rate helps to increase and stabilize the preheating temperature. Limestone with a good decomposition rate enters the rotary kiln and is easily decomposed to generate lime under high temperature. The high quality lime exchanges heat with the combustion air, so that when the fuel burns, it can be helped by the combustion of high hot air. Thus, the combustion quality of the fuel is improved, the temperature stability in the calcining system of the limestone rotary kiln is effectively ensured, and the purpose of improving the thermal efficiency is achieved. Secondly, the thermal effect of the fuel after it is completely burned in the active lime rotary kiln and the operation mechanism of the kiln should be maintained mutually and can be fully adapted and matched. Active lime rotary kiln for the material to be calcined, the heating value of the fuel and the quality of the fuel itself are more important. At the same time, it should also be fully taken into account that the source of the selected fuel, input costs, etc., should meet the requirements of the product value. The level of fuel heating value, the impact of the heat generated by the fuel combustion process is very large. The influence of combustion air on the heat generated by fuel combustion is also very large. When air is used to help combustion, it must take away some heat. At this time, the degree of heating of the combustion air and the amount of input during the combustion process must have a clear requirement, because it will affect the combustion quality of the fuel and the effective release rate of heat. How to use air in the calcining process of the lime rotary kiln has a great influence on the fuel combustion efficiency. The combustion process of fuel should have enough energy to participate in the combustion. Its purpose is to ensure that the fuel can be completely burned, releasing effective heat and completing the final calcination process. Achieve batch production.
