Question

Which of the following is a chief source of sulfur entry in the blast furnace?

• A. Iron ore
• B. Coke
• C. Sinter
• D. Flux

Hint:

Efforts to reduce sulfur content in blast furnaces often focus on using low-sulfur coke or treating the gas streams for sulfur removal.

Answer 1

The Correct Option is B

Coke is the primary source of sulfur in the blast furnace due to its sulfur content. The sulfur can then be transferred into the iron produced during the smelting process.
