Answer to Question #160406 in Physical Chemistry for deepak

Question

In the following MCQ, identify the correct option and justify.

Identify the factor favoring flooding in the blast furnace.

a. Lower Gas velocity

b. Lower viscosity of the slag

c. Non wetting slag

d. Lower coke size

Answer 1

The factor favoring flooding in the blast furnace is ‘lower coke size.’ Other factors include higher productivity also limited by liquid holdup and flooding and in the bosh region, coke is the only solid material through which gas flow up and liquid moves down (Arora, 2018). Besides, other factors include pressure drop increases with increase in gas throughput at fixed liquid throughput and increased resistance give rise to loading followed by flooding
