Airslide® Gathering System
Fly ash continuously discharges from all dust collector hoppers simultaneously. Ash becomes fluidized within the Airslide® conveyor and flows rapidly down the slope via gravity. Fluidization air is heated to further ensure proper ash flow to the Fuller®-Kinyon pump. The pump acts as a "line charger," injecting the ash into the pressurized convey pipeline while acting as an airlock between the conditions in the dust collector / Airslide® conveyor and the conveying system.

The FK Pump conveying system uses carbon steel straight piping and hard iron sweep fittings. A simple bin vent filter is required at the destination silo to vent the conveying air.

Components of The Airslide® / FK™ Pump System

Airslide® Air Gravity Conveyor

  • Conveys fluidized product via gravity through sloping trough. The conveying plenum (top) and air plenum (bottom) are separated by a proprietary 5-ply porous membrane.
  • Air supply is low pressure fan or blower package.
  • No moving parts within material flow stream
  • As an example of Airslide® capabilities, Airslide® conveyor gathering networks are installed in power plants on circulating dry scrubbers (both baghouses and electrostatic precipitators) with circulating ash/lime flows over 400 STPH.
  • Ten to twenty year fabric life is common under standard conditions.

Fuller®-Kinyon™ Pump Line Charger
  • Continuously injects bulk materials into a pressurized convey pipeline
  • Variable pitch screw continuously compresses bulk product as it enters the windbox (material/air mixing chamber). Compressed product forms a “material seal” against the convey line pressure.
  • Extremely simple operation and maintenance
  • Direct dive, electric motor
  • Over 30 pumps installed for fly ash conveyance within coal-fired power plants in the last six years. Literally thousands of pumps installed worldwide since pump was introduced in 1920’s.
