How much coal does a 100 ton lime kiln need to consume per day
Coal is an indispensable energy source in the calcination process of lime vertical kilns. For a vertical kiln that produces 100 tons of lime per day, its coal consumption has a relatively clear calculation method and approximate range.
Normally, producing one ton of lime requires approximately 120 kilograms of coal consumption. This data is based on the normal operating parameters of the lime vertical kiln, the calorific value of coal, and the calcination process, among other factors. So, for a vertical kiln that produces 100 tons of lime per day, the daily coal consumption can be calculated simply: 100 tons of lime multiplied by 120 kilograms of coal consumption per ton of lime, which is 100 × 120=12000 kilograms, converted to 12 tons.
However, the actual coal consumption is not constant. The quality of coal, such as calorific value and ash content, directly affects combustion efficiency, which in turn affects lime production and coal consumption. In addition, factors such as the operational level, equipment condition, and quality of limestone in vertical kilns can also cause fluctuations in coal consumption to a certain extent. Therefore, in actual production, it is necessary to continuously optimize processes and improve operational skills to achieve rational utilization and cost control of coal.
