Oxygen-enriched operation technology for zinc oxide volatilization kilns
Thread Content
Some zinc smelters in China have adopted oxygen-enriched combustion technology in the zinc oxide volatilization kilns for treating zinc-containing slag, and we are seeking information and data on the technical and economic aspects related to this. Thank you
I’m not sure which specific information this friend would like to know?
Oxygen enrichment in a blast furnace for the oxidation of zinc can increase production
1. Oxygen concentration range at the entrance of the furnace, and pressure of oxygen-enriched air entering the furnace. 2. Comparison of zinc recovery rates and impurity levels before and after oxygen enrichment. 3. Selection of oxygen production methods: cryogenic oxygen production/PSA/VPSA. 4. Oxygen production pressure and power consumption (oxygen compressors, circulating cooling water pumps). 5. Modifications required to adapt the furnace structure. 6. Estimated investment costs for these modifications, taking into account the furnace specifications...... I hope to discuss this separately.
