Question:
Metallurgical coke should have a desired property of
Metallurgical coke should have a desired property of
Show Hint
High Fusion = Less Melting = Better permeability in the furnace.
Updated On: Jul 4, 2026
- High volatile matter
- Low fixed carbon
- High ash fusion temperature
- Low Brittleness
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Coke acts as fuel, reductant, and structural support in the blast furnace.
Step 2: Meaning
If the ash in the coke melts at low temperatures, it can cause clinkering and impede gas flow.
Step 3: Analysis
Coke needs high fixed carbon for fuel value and low volatile matter. A high ash fusion temperature ensures the ash doesn't melt prematurely in the stack.
Step 4: Conclusion
A high ash fusion temperature is a critical quality parameter for metallurgical coke. Final Answer: (C)
