Overall approach
The project H2II is focused on the study of the potential of pulsed hydrogen injection into the shaft of the blast furnace. Injecting hydrogen into this zone, above the cohesive zone, should promote indirect reduction of the burden. Pulsed gas injected is expected to achieve a higher penetration depth into the blast furnace burden, thus improving efficiency of this process.
Starting from an existing sequence impulse injection (SIP) system for injecting additional oxygen into the blast furnace tuyeres, the SIP system will be adapted to inject hydrogen into the blast furnace’s shaft. A functional test rig will be designed to test the validity of this approach. Accompanying simulations of the test rig as well as the full blast furnace’s reaction kinetics will be used to inform and guide the design of the functional test rig as well as the later industrial validation trial. The validation will be conducted at an industrial blast furnace.
Objectives
The main goals of this project, over its 42 month duration, are:
- Design a functional test rig for a single injection unit
- Study the pulsed gas injection by means of simulations
- Validation of the process via an industrial plant trial
- Develop a full scale design
