ABSTRACT:
A solid fuel burner apparatus is provided having a combustion chamber surrounded by a housing and having a solid fuel and primary air nozzle attached to the combustion chamber and located in the housing for directing pulverized solid fuel and air into the combustion chamber. A solid fuel and primary air input is connected through the housing to the solid fuel and primary air nozzle for directing solid fuel thereinto. A secondary air input is connected to the housing for directing air under pressure into the housing and from the housing into the combustion chamber. The housing is divided between first and second compartments and a proportioning damper system divides the input secondary air between the first and second compartments of the housing. Dampers are used to proportion secondary air between first and second compartments from an inlet plenum and diffusion vanes direct the primary and solid fuel into the combustion chamber with a predetermined pattern to control the flame.
