Relationship between oxygen consumption per ton of ammonia and coal consumption per ton of ammonia in fixed-bed batch oxygen-enriched ammonia production
Thread Content
Our company has some fixed-bed batch oxygen-enriched gas production furnaces. Based on the data, it seems to me that during normal operation, the oxygen consumption per ton of ammonia is not directly related to the coal consumption per ton of ammonia. I would like to hear the opinions of my colleagues on this matter.
I don’t think whether it’s rich in oxygen has anything to do with the coal consumption per ton of ammonia.
Reply to 2# hebeiren: Oxygen-enriched gas production can significantly reduce the blowing time, improve carbon utilization efficiency, and greatly decrease residual carbon in the slag.
Oxygen-enriched gas production only increases the gas output per unit equipment; it does not have a significant effect on reducing consumption. If there is no noticeable decrease in the carbon dioxide content in the gas, how can consumption be reduced?
A fixed-bed batch oxygen-enriched gas production furnace should be effective; the poster of sxjxwml must be from Zhangjiagang! Could you please provide detailed information on the gas composition, coal consumption before and after the technical upgrades in your company, as well as the residual carbon content in the slag after switching to oxygen-enriched gas production furnaces?
That’s true; some comparative data should be presented
First of all, you should also provide the relevant data. It can be said that oxygen enrichment can effectively increase the gas production per furnace, as it reduces the blowing time. However, if coal consumption remains unchanged, it is recommended to reduce the gas production load per furnace appropriately; only by making proper adjustments can coal consumption be lowered. I believe the operation of your furnaces is quite stable, but one cannot judge anything based on just a single day’s data – time is what truly reveals the truth. After gas production, is combustion carried out or liquid ammonia produced? For liquid ammonia, pay attention to the nitrogen content.
