Abstract

A burner adapted for use with pulverised coal has an annular swirling coal and primary air supply (2) located inside a swirling annular secondary air supply (3) with a hollow rotationally summetrical flame stabil­ ising body (7) located centrally of the swirling coal/air streams. The flame stabilising body can include a ring of nozzles (24) on a domed downstream end (8) for egress of start-up fuel therefrom.
