Abstract
A burner for the combustion of coal dust in which a stream of primary air and coal dust mixture is conducted through a dust conduit connected to a primary dust tube. A secondary air tube surrounds the primary dust tube, and a tertiary air tube surrounds the secondary air tube. The secondary and tertiary air tubes are connected to a helically-shaped input housing, and a conically flared section extends from each of the secondary and tertiary air tubes. An angular momentum is applied in the dust conduit divides the primary air and coal dust mixture into high-dust and low-dust partial streams, so that the high-dust partial stream flows through the primary dust tube, and the low-dust partial stream flows through the primary gas tube.
