Abstract
Pulverized coal is ignited, to furnish energy for warm-up or low load operation of a coal burning furnace, by a technique which does not require the combustion of significant quantities of liquid or gaseous fuels. The direct ignition of pulverized coal in accordance with the present invention contemplates the delivery of a dense phase coal/air stream to an ignition zone where it receives ignition energy and the thus ignited mixture is thereafter contained in a recirculation region until the flame becomes self-sustaining.
