Tuyeres TRIZ Cases
- Blast Furnace Hydrogen Gas Injection for Low-Coke Operation
Dual reducing-gas injection at tuyere and shaft levels cuts coke use and CO2 while stabilizing blast furnace gas flow.
- Oxygen-Channel Tuyere Sleeve to Prevent Furnace Front-End Melting
Controlled oxygen outlet position, angle, and jet speed help protect the tuyere front from high-temperature melting and slag damage.
- Packed Bed Gas Injection Layout for Uniform Circumferential Flow
Multiple side nozzles and a defined gas flow index balance circumferential flow in a cylindrical packed bed, improving heating and reduction stability.
- Blast Furnace Gas Injector Joints for Thermal Expansion Sealing
Cardan joints and flanged seals keep blast furnace reducing gas injectors gas-tight while accommodating thermal expansion and easing maintenance.
- Blast Furnace Intermediate Gas Injection for Lower CO2 Emissions
An intermediate injection level for CO-rich top gas reduces coke use and CO2 emissions while preserving blast-furnace productivity.
