Characteristics of ABB Pulverised Fuel Meters

ABB PFMaster solids flow meters have proven to be very useful worldwide in coal-fired power stations for monitoring and controlling Pulverised Fuel (PF) velocity and mass-flow rates at various locations in the boiler fuel supply system. However, little has been published of the meter's response on a pneumatic conveyor where both the air and the solids input were each measured independently. This is a brief report of tests carried out on a two such metersin a university pneumatic conveyor.
