In blast furnace, the highest temperature is in

Options

  1. Areduction zone
  2. Bslag zone
  3. Cfusion zone
  4. Dcombustion zone

Correct answer

D. combustion zone

Step-by-step solution

In blast furnace the highest temperature is in combustion zone. In the first stage, coke burns to produce CO ₂ which rises temperature. C + O ₂ CO ₂+ Heat This reaction is exothermic and hence temperature is 2170 K . It is known as combustion zone.
