GENERAL KNOWLEDGE

Detailed explanation-1: -Settling chambers are used to remove comparatively bigger particles like particulate matter from gas/air flow. When this is done by the action of gravitation force it is called gravitational settling chamber.

Detailed explanation-2: -Gravitational force may be employed to remove particles where the settling velocity is greater than about 13 centimeters per second (cm/s) (25 feet per minute (ft/min)). In general, this applies to particles larger than 50 µm if the particle density is low, down to 10 µm if the material density is reasonably high.

Detailed explanation-3: -Gravity settling chambers are the oldest and simplest means of removing large diameter suspended particles from a gas. High-efficiency settling chambers are often fitted with baffles or deflectors to change the gas flow direction.
