  • Gravity settling chambers hydraulics and pneumatics

    Gravity settling chambers hydraulics and pneumatics

    Gravity settling chambers. The simplest type of equipment for separating solid material from a gas stream is the gravity settling chamber in which the velocity of the gassolid stream is reduced, and the residence time increased, so that the particles fall out of suspension under the influence of gravity. Such a device is shown in Figure 7.2.
