Abstract
A burner for solid fuel in pulverulent form has a central conduit for primary combustion air, a fuel conduit surrounding the central conduit for admission of the pulverulent fuel, and one (or two concentric) secondary-air outer conduits. The annular space between the fuel conduit and the single (or the innermost) outer conduit is subdivided into two annular channels by an intermediate conduit. An inlet arrangement is provided for feeding combustion air into one of these channels, and another arrangement permits the selective feeding of either only combustion air, or of a mixture of such air with pulverulent fuel, into the other of the annular channels.
