What is the height and inner diameter of a 200 ton vertical lime kiln
As a key equipment for producing lime, the design and construction of lime kilns have a significant impact on the quality and yield of lime. Especially for vertical lime kilns, as a widely used equipment in current industrial production, their height and inner diameter are important factors determining their production capacity and efficiency.
1、 Basic functions and structure of vertical lime kiln
Vertical lime kilns are mainly used for producing lime and carbon dioxide gas. Its basic structure includes kiln body, feeding system, discharging system, combustion system, and exhaust gas treatment system. The kiln body is the main working area, usually composed of high-temperature resistant materials such as high alumina bricks, insulation layers, etc. The interior is cylindrical or conical drum shaped, used for calcining limestone.
A vertical lime kiln decomposes limestone into lime (CaO) and carbon dioxide gas at high temperatures by controlling the temperature and combustion atmosphere inside the kiln. Throughout the process, calcium carbonate (CaCO) in limestone undergoes calcination reaction to produce calcium oxide (CaO) and carbon dioxide (CO ₂), which is then emitted into the atmosphere through the exhaust gas treatment system.
2、 The height of a 200 ton vertical lime kiln
The height of lime kilns varies depending on the production process and scale, generally ranging from a few meters to several tens of meters. The height selection is determined after comprehensive consideration of various factors such as production process, production scale, and reaction time of limestone and fuel in the kiln.
For a 200 ton vertical lime kiln, its height is usually between 30 meters and 40 meters. Taking a specific 200 ton vertical lime kiln as an example, its kiln height is 36 meters. The selection of this height ensures that limestone and fuel react fully in the kiln, producing high-quality hydrated lime while achieving high production efficiency. If the height of the kiln body is too low, it may cause insufficient reaction between limestone and fuel in the kiln, affecting the quality and yield of lime; If the height of the kiln body is too high, it will increase production costs and equipment complexity, which is not conducive to industrial production.
3、 Inner diameter of 200 ton vertical lime kiln
The inner diameter of a vertical lime kiln is another key factor affecting its production capacity and efficiency. The size of the inner diameter directly determines the volume and calcination area inside the kiln, thereby affecting the yield and quality of lime.
For a 200 ton vertical lime kiln, its inner diameter is usually between 4 and 5 meters. Taking a specific 200 ton vertical lime kiln as an example, its inner diameter is 4.8 meters. The selection of this inner diameter ensures sufficient volume and calcination area inside the kiln to meet the production demand of 200 tons per day. Meanwhile, a reasonable inner diameter can ensure even distribution of limestone and fuel in the kiln, improving calcination efficiency.
The selection of inner diameter also needs to consider factors such as the thermal conductivity of the material, the stability and safety of the kiln body. Excessive inner diameter may lead to a decrease in kiln stability and increase the risk of equipment failure; However, a smaller inner diameter may limit the production scale and reduce the economic efficiency of the equipment.
4、 Other influencing factors
In addition to height and inner diameter, the production capacity and efficiency of a 200 ton vertical lime kiln are also affected by various other factors, such as calcination temperature, combustion atmosphere, fuel type and quality, properties and particle size of limestone, etc.
The calcination temperature is one of the key factors affecting the quality and yield of lime. Excessive temperature may cause lime to overheat, affecting its activity and effectiveness; However, excessively low temperatures may lead to incomplete decomposition of limestone, reducing the yield and quality of lime. Therefore, in actual production, it is necessary to control the calcination temperature reasonably based on factors such as the properties and particle size of limestone.
The combustion atmosphere also has a significant impact on the calcination process of lime. Oxygen enriched combustion can improve the calcination efficiency and quality of lime, but it also increases fuel consumption and exhaust gas treatment costs. Therefore, it is necessary to choose a suitable combustion atmosphere based on the actual situation.
The type and quality of fuel are also important factors affecting the production capacity and efficiency of lime kilns. Different fuels have different calorific values and combustion properties, which have different effects on the calcination process of lime. Therefore, when choosing fuel, it is necessary to comprehensively consider factors such as its economy, environmental friendliness, and applicability.
The height and inner diameter of a 200 ton vertical lime kiln are one of the key factors affecting its production capacity and efficiency. In the actual design and construction process, it is necessary to make reasonable choices based on various factors such as production technology, production scale, and the reaction time of limestone and fuel in the kiln. At the same time, factors such as the thermal conductivity of the material, the stability and safety of the kiln body need to be considered to ensure the reliability and economy of the equipment.
Attention should also be paid to other influencing factors such as calcination temperature, combustion atmosphere, fuel type and quality on the quality and yield of lime. By comprehensively considering these factors, the design and construction process of a 200 ton vertical lime kiln can be optimized to improve its production capacity and efficiency, providing high-quality lime products for industrial production.
