Multi cyclone dust collector consists of a number of small diameter cyclones, operating in parallel & having a common gas inlet & out let. MDC operate on a same principle as cyclone – creating a main downwards vortex and an ascending inner vortex.They are more efficient than single cyclones because they are longer and smaller in diameter. The longer length provides longer residence time while the smaller diameter creates greater centrifugal force. These two features result in better separation & dust particulates.
Mechanical dust collector is an equipment which extract dust from the boiler & retains dust particle inside the dust collector and lets clean air left to the atmosphere.
The design & size are various as per the volume of dust generated & volume of air handle.
