Solid fuel burner

Patent ·
OSTI ID:5909948
A solid fuel burner apparatus is provided for burning low density, low mass fibrous fuels such as paper waste and biomass. The burner includes a combustion chamber having a solid fuel and primary air nozzle attached to one end thereof for directing pulverized solid fuel and air into the combustion chamber. The solid fuel and primary air nozzle has a spinning mechanism for spinning the solid fuel and air into the combustion chamber in one direction of rotation. A secondary air input is provided for feeding secondary air into the combustion chamber and includes means to spin the secondary air from the secondary air input into the combustion chamber in a direction opposite in rotation to the direction of rotation of the solid fuel and primary air. A gas fuel input has a flame disk and is positioned to feed gas into the combustion chamber in the center portion of the solid fuel and primary air nozzle to create additional stability in the combustion of the solid fuel in the combustion chamber. A second gas nozzle will allow the burner to operate entirely on gas where insufficient fuel is available.
