Product Description
Side Blown Furnace Equipment and Technical Parameters
1. Equipment Overview
Side blown furnace is a vertical smelting reactor with horizontal side tuyeres for high-pressure oxygen-enriched air injection, widely applied in vanadium slag melting, ferroalloy smelting, non-ferrous metal matte converting and hazardous solid waste treatment.
High-speed oxidizing/reducing gas blown from side nozzles forms strong agitation inside the molten bath, featuring fast reaction speed, high raw material utilization, compact layout and low investment. It can be matched with continuous feeding, waste heat recovery and full flue gas purification systems.
2. Complete Equipment System Composition
