Chapter 13, Problem 4RQ

(a)

Interpretation Introduction

Interpretation:

A bag filter remove particulates from stack gases should be explained.

Concept introduction:

Industrial smog contains particulate matter in high levels. Particulate matter contains mineral matter which occurs in coal. Minerals don’t burn even in thunderous fire. Due to this mineral matter left as bottom ash and much ashes are mixed with the air in the atmosphere. This fly ash covers the surrounding and covers everything with dust. It contributes many respiratory problems. Thus, particulate matter can be removed from smoke stack gases with the help of different devices. The use of devices depends upon the size of power plant, coal burned etc.
