Abstract
A particulate deflagration enhanced firebox for burning particulate fuel either alone or in combination with other fuels and the associated method. The firebox may be employed in association with a power plant where the heat from the firebox is used to generate electricity. Fine fuel particles are fed to a mixing drum or box by a pre-measured auger system where the fuel is mixed with dried, compressed combustion air in a desire fuel to air ratio. The fuel mixture enters the combustion firebox or boiler either alone or in association with other fuels where it is ignited. The hot combustion gases leave the firebox and are vented through the firebox's normal route which generally includes passing through a precipitator for remove particulates before exiting to atmosphere via a chimney stack.

A particulate deflagration enhanced firebox for burning particulate fuel either alone or in combination with other fuels comprising:
- a particulate fuel delivery system attaching a main fuel cell with a mixing box for delivering a measured portion of particulate fuel from the main fuel cell to the mixing box,
- a dried and compressed air delivery system attaching air drier and air compressor with the mixing box for delivering a portion of dried and compressed combustion air from the air drier and air compressor to the mixing box,
- mixing means provided in the mixing box for mixing the measured portion of particulate fuel with the portion of dried and compressed air to form a fuel and air mixture,
- a fuel and air mixture delivery system attaching the mixing box with a firebox for delivering a portion of the fuel and air mixture to the firebox, and
- ignition sources provided in the walls of the firebox for igniting the fuel and air mixture under deflagration conditions to create hot combustion gases.
A particulate deflagration enhanced firebox comprising:
- a particulate fuel delivery system attached to and delivering a measured portion of particulate fuel to a mixing box,
- a dried and compressed air delivery system attached to and delivering dried and compressed combustion air to the mixing box,
- mixing means provided in the mixing box for mixing the particulate fuel with the dried and compressed air to form a fuel and air mixture, and
- a fuel and air mixture delivery system attached between the mixing box and a firebox and delivering the fuel and air mixture to the firebox.
A method for operating a particulate deflagration enhanced firebox comprising:
- mixing particulate fuel with dried and compressed combustion air to form a fuel and air mixture,
- feeding the fuel and air mixture into particle deflagration enhanced firebox, and
- firing an ignition source located within the walls of the firebox to ignite the fuel and air mixture.
