How much coal is needed to burn one ton of lime in a new vertical environmentally friendly lime kiln
In the field of lime production, the new vertical environmentally friendly lime kiln has attracted much attention due to its high efficiency and energy-saving characteristics. The amount of coal required to burn one ton of lime is closely related to kiln design, process optimization, and fuel quality.
Currently, the coal consumption of technologically advanced vertical environmentally friendly lime kilns is usually controlled at around 120 kilograms of standard coal per ton of lime. Behind this data is the innovation of kiln structure, such as the use of vase shaped inner tanks and circular flue forced ventilation designs, which effectively reduce heat loss and improve thermal efficiency. At the same time, the kiln body is equipped with insulation and thermal insulation layers to further reduce heat loss, so that the heat generated by coal combustion can be more fully used for the calcination of limestone.
In addition, the new vertical environmentally friendly lime kiln also has certain requirements for fuel quality, and it is generally recommended to use solid fuels with a calorific value of over 5000 kcal. If inferior coal or bituminous coal is used, although production can still be carried out, various technical and economic indicators will be affected, and coal consumption may increase accordingly.
In actual production, by continuously optimizing process parameters and strengthening equipment maintenance management, the new vertical environmentally friendly lime kiln is expected to further reduce coal consumption and achieve greener and more efficient production.
