Abstract
A burner for solid particle fuels such as shavings or pellets. The invention includes a helical piston to deliver fuel particles up an inclined tube into a cup having an oxygen delivery tube for combustion. The helical piston is axially extendable and retractable to first advance material up the tube without rotation, and then retract with rotation so as to screw itself into the next charge of material to be advanced. Combustion heat may be used to drive a Stirling engine or other mechanism for converting heat into other useful energy or power, such as using the burner as a component of a combined heat and power (CHP) system.
