Coal consumption calculation

This post was last edited by YUZHOU582462731 on 2019-8-7 at 20:18. The amount of water-coal slurry is known to be 100, with a slurry concentration of 61%. Given that the ammonia production volume is 500 tons in 8 hours, how can the coal consumption per ton of ammonia be calculated? Thank you
It is necessary to first find the slurry density data and the coal quality analysis data for the raw coal. The calculation is 500/8*100*slurry density*slurry concentration*(1–external water); the result of this calculation gives the amount of raw coal. If it needs to be converted to standard coal, then conversion based on heat content should be used
First, determine the numerator and denominator for your coal consumption. Based on the conditions you provided, it is necessary to convert ammonia into hydrogen before calculating the coal consumption; in this case, the amount of syngas that is used in the ammonia synthesis process must be deducted. Otherwise, if calculated in this way, the KPIs of the coal gasification unit will be affected by factors downstream. If the syngas flow measurement is ready, it is more appropriate to use the expiration date for calculation. The coal consumption can be calculated fairly easily: measure the density of the coal slurry in the laboratory, then convert it based on the concentration of the coal slurry and divide by the denominator – and the result is obtained quickly. Or calculate it directly based on the coal feeding amount.
