For reference, a cyclone is a principle and structure for separating particles by centrifugal force acting on the powder by causing a pivoting motion.

As shown, as the cylinder becomes narrower toward the bottom of the cylinder, the swirl flow rate increases so that the particles gain sufficient centrifugal force. Therefore, the collection of fine particles becomes effective. Since the downward swirl flows past the distal end of the inner cylinder, the inner layer of the large outer vortex deviates from the low pressure region along the central axis and separates itself.

This separation from the outer vortex becomes larger as it approaches the apex at the bottom of the cone, eventually joining the ascending inner vortex and flowing out through the inner cylinder while turning upward.

Such a cyclone has the advantages of simple structure, low installation cost and low maintenance cost, and operation at high temperature, which is applied in the present embodiment.
