Detroit® Pellet Metering Feeder & Pellet Distributor Spout

Detroit Stoker Company (DSC) has extensive experience with biomass fuel feed systems. DSC’s experience has revealed many shortcomings when these fuel feed systems are used for feeding pelletized fuel. Pellets present unique difficulties to the fuel feed control required for optimal combustion. DSC’s fuel feed equipment, developed specifically for pelletized fuel, can eliminate most issues encountered when firing pelletized fuel by evenly and consistently distributing the fuel into the furnace.

Biomass fuel feed systems often consist of screw feeders (either single or twin-screw metering bins) and rotary vane feeders. When used for pelletized fuel feed control, issues including the following are often noted:

• Uncontrollable fuel flow due to pelletized fuel flooding past screw flights.
• Inconsistent fuel flow as screw flight clear, a “slug” feeding effect is created. This can lead to pulsations in the furnace and load instability.
• Without a rotary vane feeder, negative furnace draft can pull pelletized fuel from the gaps in the screw conveyor.
• Standard rotary valves can cause fuel degradation leading to increased suspension burning and hot spots near the distributor throat opening.
• Pellets are not evenly distributed across the width of the distributor leading to insufficient grate coverage.
