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
2.1 Furnace Body Main Unit
Furnace Shell
All-welded cylindrical steel shell with integral water jacket structure; slag line, tuyere zone and furnace arch adopt thickened water cooling to resist high temperature erosion and thermal shock. Temperature and water leakage sensors are arranged along the shell.
Refractory Lining
Tuyere zone: high wear-resistant chrome-magnesia brick / magnesia-chrome spinel brick
Molten bath & slag zone: fused magnesia brick
Furnace top: high alumina castable + heat insulation layer
Side Tuyere Assembly (Core Component)
Horizontal multi-layer side blowing tuyeres, double-layer water-cooled copper composite structure.
Oxygen-enriched air, fuel gas, cooling medium are separately conveyed through internal channels; each tuyere is equipped with independent flow, pressure and temperature monitoring interlock.
Tap Holes & Slag Ports
Metal tapping hole and slag tapping hole arranged at different elevation positions; hydraulic tapping opening/closing machine, mud gun for blocking tap holes.
Furnace Top & Flue Outlet
Water-cooled furnace roof with feeding port, spare manhole and main flue gas outlet connected to waste heat boiler.
Stainless steel air distribution manifold for each tuyere, independent flow control valve, anti-backfire safety cut-off valve, pressure relief device.
2.3 Feeding System
Raw material silos, quantitative screw feeders / belt weighing feeders (weighing accuracy ±0.3%~±0.5%)
Sealed feeding chute to prevent flue gas escape and dust leakage
Optional auxiliary fuel feeding device (coal powder, natural gas) for temperature compensation
2.4 Cooling Circulation System
Closed soft water circulation system for furnace water jacket and tuyeres
Industrial circulating cooling water for auxiliary equipment
Online monitoring of water inlet/outlet temperature, flow and pressure; automatic alarm and interlock shutdown under abnormal conditions
2.5 Hydraulic & Tapping Equipment
Hydraulic station for tapping machine, slag door push rod, furnace cover lifting; constant pressure variable pump, oil temperature cooling and filtration system.
2.6 Waste Heat & Flue Gas Treatment System
Waste heat boiler: recover high-temperature flue gas heat to produce steam for power generation or production heating
Flue gas cooling + bag dust collector: dust removal efficiency ≥99.8%
Desulfurization & denitrification device to meet environmental emission standards
Automatic linkage of feeding, oxygen blowing, air supply and temperature regulation
Real-time monitoring of tuyere pressure, oxygen concentration, molten pool temperature, cooling water parameters
Automatic tapping timing, historical data storage, fault alarm record, production report export
