Tuyeres TRIZ Cases
- Blast Furnace Lance Segmentation for Coal Combustion
Downstream LNG injection increases coal temperature while segmentation prevents lance wear from thermal stress.
- Blast Furnace Raceway Abnormality Detection
Dynamic brightness thresholds and change rates distinguish sudden clogging from gradual temperature fluctuations for accurate early detection.
- Fluidized-Bed Reduction Reactor Charging System for Iron Ore
Independent charging lines prevent blockages and stabilize fluidized bed operation.
- Tuyere Stock Temperature Monitoring via Heat Conduction Layer
A tuyere stock integrates a heat conduction layer to transfer thermal data from the refractory interior to an external sensor for real-time detection.
- Stationary Hearth Furnace Iron Reduction
A stationary hearth furnace circulates heated fluids to dry and reduce iron oxide into metallic iron nodules.
- Blast Furnace Stack Gas Injection Reduces Coke Consumption
Segmented stack-level gas injection reduces coke consumption and CO2 emissions while maintaining stave durability.
- Composite Sparger Heat Conduction Corrosion Resistance
A composite sparger uses a thermally conductive metal substrate to protect the corrosion resistant layer.
- Fluid Assisted Particle Injector Tapered Bore Plugging
A fluid assisted particle injector uses a tapered internal bore to accelerate carbon and lime particles through the metallurgical furnace.
- Shock Wave Injection for Blast Furnace Reaction Kinetics
Shock waves accelerate chemical reactions in blast furnaces, resolving inefficient gas injection in the dead man's region.
- Smelting Lance Extraction Track and Carriage System
Segmented track and hoist mechanism extracts heavy smelting lances, reducing maintenance downtime in continuous operations.
- Partially-reduced iron production via exhaust gas circulation
A partially-reduced iron producing apparatus uses an exhaust gas circulation device to supply oxygen-containing gas for thermal reduction.
- Rotating Flow Diverter Cone for Shaft Furnace Gas Distribution
A rotating flow diverter cone directs reducing gas through a shaft furnace to improve burden saturation and material uniformity.
- Blast Furnace Injector for Deep Gas Penetration
Protruding injector nozzle extends hot reducing gas injection into the shaft furnace interior.
- Metallurgical Furnace Segmented Tubes Burner
Segmented upper and lower tubes with a fuel feeder enable the burner to process impure raw materials efficiently.
- Blast Furnace Tuyere Structure with Flexible Joint
A flexible joint connects the blowpipe to the tuyere stock, absorbing thermal deformation differences between the furnace shell and the conduit.
- Hearth Furnace Segmentation for Iron Reduction
Segmented heating zones in a hearth furnace reduce energy consumption and carbon loss during metallic iron production.
- Independent Carbonaceous Feed Lines for Direct Smelting
Independent carbonaceous feed lines supply injection lances separately, preventing single lance breakdowns from halting the entire smelting process.
- Dual-Channel Tuyere for Efficient Steel Decarburization
Concentric tuyeres inject separate gas streams to decarburize molten steel while suppressing chromium oxidation.
- Solids Injection Lance Puncture Detection System
A solids injection lance integrates an annular inert gas chamber to detect wall punctures via pressure changes.
- Side-Submerged Lance Segmentation for Clog-Free Maintenance
Segmented injection pipes allow inner tube removal without lowering the molten bath, resolving clogging and productivity trade-offs.
- Swirl Inducer Vane Design for HIsmelt Gas Flow
Segmented vanes induce swirl in high-temperature metallurgical vessels while minimizing turbulence and easing manufacturing from refractory materials.
- Linear Hearth Furnace Shrouded Return for Iron Reduction
A linear hearth furnace uses a shrouded return to recycle heated gases from fusion zones for preheating moving hearth sections.
- Blast Furnace Stack Wall Enlargements for Reducing Gas Injection
Internal wall enlargements in the blast furnace stack enable targeted reducing gas injection below the structural modifications.
