Cutting Edge Technology Pilot Project –Gas Flow Measurement Systems for
Cement Plants optimization
By – Kamal KumarChief General Manager
HOLTEC CONSULTING PRIVATE LIMITED
Methodology adopted by PROMECON’s MECONTROL Air
System utilizes the triboelectric principleMetal sensors placed parallel to flowElectrical signals created by dust particlesParticle movement correlated & referencedTime shift & distance provide flow velocity
Aspects of measuring dusty gas streams
Location of the duct (accessibility & safety)Temperature, Pressure and MoistureFluctuation in flow rateDust concentration of the stream
Areas
Vertical Roller MillTube MillPreheater/ Precalciner kilnLong Wet/ Dry kilnDirect fired burning systemKiln gas bypass system
Online measurement
