Cyclone and multi-cyclone filters are typically used for capturing ash and soot generated during the combustion of solid fuels, especially lignite coal, in fuel boilers. They are employed in smoke gas washing and filtering systems for capturing and separating particulates contained in the flue gases that also contain volatile ash and soot. The design of cyclone filters is tailored to the characteristic properties of the dust particles to be separated, ensuring that the cyclones achieve the highest filtration efficiency, thus facilitating an effective filtration process.
Cyclone filter design takes into account various parameters such as the density and particle size of the dust particles to be filtered.
The dust-laden gas enters the cyclone tangentially at high speed through the cyclone inlet, and through the construction of the cyclone, it is given a helical flow pattern, directing particles with a higher density than the carrier medium toward the cyclone walls through centrifugal force. Due to the sudden change in velocity within the cyclone, particles lose their inertia and are filtered through the cyclone walls, flowing into the lower conical collection bunker. As a result of this mechanism, the gas, free from the dust it contained, is discharged to the outside from the top of the cyclone through the outlet pipe.
Depending on the abrasive properties of the dust particles, cyclones can be manufactured from various thicknesses of S 235 JR quality material or Cr-Ni stainless material.
