Cyclone and multi-cyclone filters are commonly used to capture ash and soot resulting from the combustion of solid fuels, particularly lignite coal, in fuel boilers.
They are utilized in flue gas cleaning and filtering systems to capture and separate particulate matter contained within the flue gases that contain fly ash and soot. The design of the cyclone filter, tailored to the characteristics of the dust particles to be separated, ensures that the filtration efficiency of the cyclones is maximized, resulting in an effective filtration process.
The cyclone filter design takes into account various parameters such as the density of the dust particles to be filtered, particle size, and other factors.
Dusty gas enters the cyclone tangentially at high speed, and the cyclone construction induces a helical flow pattern, directing particles with a higher density than the carrier medium toward the cyclone walls by centrifugal force. Due to the sudden change in velocity within the cyclone, the particles lose their inertia, allowing them to be collected and flow down to the lower conical collection hopper. As a result, the gas, now free of dust particles, is discharged through the outlet pipe at the top center of the cyclone.
