The solid fuel burner includes a combustion chamber (20) having a floor (21) occupied by a fuel bed, a primary air supply (15) under the combustion chamber floor, and a secondary air supply (12) within the combustion chamber and above the fuel bed, for improving combustion of the fuel. Means (10) for adjusting the amount of air from each supply may be provided, and the secondary air supply (12) may be positioned over part of the fuel bed just outside the burning zone. The secondary air supply (12) may be operated in conjunction with a fuel feeder to minimise smoke generation when new fuel is added to the fuel bed, and exhaust gases may be routed through a chimney (5) including a fines arrester (51) for trapping fine particles. Virtually smokeless operation can be achieved without special fuels. The burner may be applied to water heating systems. <IMAGE> |
