Report Summary The Rotary Combustor is a novel concept for burning coal with low SO2 and NOx emissions. It burns crushed coal in a fluid bed where the bed is maintained in a rotating drum by centripetal force. Since this force may be varied, the combustor may be very compact, and thus be a direct replacement for a p.c. burner on existing boilers.
