However, due to its lightweight design, the CCX is well suited for such upgrades. For plant owners, this means the ability to boost preheater operation at a lower cost. CCX Operating Principle The CCX cyclone combines heat exchange and material separation in one process, ensuring a more efficient cyclone with low pressure drop.
Mar 01, 2018· Fig. 12 shows the comparison between the tangential velocity of the optimized cyclone and the preheater cyclone at section z = 7 m versus the radius of the cyclones. Tangential velocity is the dominant component of gas flow in the cyclone, which affects the centrifugal force; with an increase in velocity, the force increases.
Increasing the preheater cyclone dimensions reduces the pressure drop. But for any given cyclone geometry, stable preheater operation (without raw meal falling through the riser ducts) requires a certain minimum gas velocity. Kiln gases Ashes/residues Preheated raw meal inlet Alternative fuel inlet Tertiary air Emergency cold raw meal inlet ...
