Biomass Burner for Aeroglide Dryers

Turn Waste By-Products Into an Alternative Fuel Source

The Biomass Burner system, for use with an Aeroglide conveyor or rotary dryer, consists of a carbon steel burner enclosure and stack, complete with fire brick and castable refractory.  A rain hood is mounted at the top of the burner stack to shield the exhaust during inclement weather conditions.

The burner feed system consists of a twin screw auger and pneumatic carrying system for cellulose-based or other flammable particulate material such as sawdust.  Product from the screw is sent to a radial blade fan designed to pneumatically feed the burner chamber with the pre-dried biomass fuel.  The cyclonic suspension of the particulate in the hot air stream of the burner fully burns the material, providing hot air for the process equipment.

The screw feeder feed rate is thermostatically controlled by the dryer or oven control system.  To maintain the preset setpoint temperature of the dryer or oven,  the feed rate of the auger will change to provide the appropriate mass of biomass for the required energy of the system, modulating much like any other conventional heat source. 

Applications
Fine particular cellulose materials such as sawdust, dried wood chips, charcoal, coal, corn, thermoplastics.
