Overview
PCI Injection Lance Replacement made Safe & Easy
The blast furnace is the heart of any integrated steel plant. It is responsible for producing the molten iron that is the primary input for steelmaking. In recent times, Pulverized Coal Injection (PCI) / Coal Dust Injection (CDI) has transformed how blast furnaces operate. PCI offers various advantages, such as increased blast furnace productivity and reduced coke consumption, which translates to substantial cost savings. Also, by partially replacing coke, a more carbon-intensive fuel, PCI helps reduce greenhouse gas emissions.
In PCI, finely ground coal is injected directly into the blast furnace through injection lances. Harsh operating conditions inside the blast furnace, where temperatures reach as high as 1200°C, cause these injection lances to experience significant wear and tear, requiring periodic replacement. The critical function of insertion & removal of injection lances is facilitated by employing Non-Return Valves (NRV) mounted on each Tuyere.
Safeguard your lance replacement operation with our Ball Check Valves.
Application Criticality
Common challenges encountered during injection lance replacement:
- Possibility of serious accidents due to leakage of hot blast gases at ~1200°C
- Unsafe operation due to jamming/failure of internal components of NRV
- Loss of productivity due to the requirement of BF shutdown/downtime for injection lance replacement
- Difficulty in fast turnaround due to heavy & cumbersome equipment
IndiTech offers a special lifting ball type check valve (also known as bullet valve) to solve the challenges mentioned above. Its simple design, tight sealing and high performance make it ideal for this critical application.
