Volumetrric Vs Gravimetric Mode : Feeder Coal properties constantly vary due to sizing differences and the adverse impact of moisture. These affect heating value, flow characteristics and density.The resultant density changes are measured by the Gravimetric Feeder.   The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand  This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.  Benefits of Gravimetric Feeder Fuel Savings through Improved Boiler Efficiency Improved Combustion Efficiency/LOI Less Slagging and Fouling, leading to Less Corrosion Less NOx through Better Control of Excess Air Stability and Improved Response of Combustion Controls Improved Pulverizer/Cyclone/Combustor Performance Reduced Safety Concer...
