Abstract
The lance of the invention includes a sleeve (2A) which conveys air under pressure around a central tube (1) which conveys the pulp that is to be sprayed and dispersed. The wall of this tube is pierced by separation holes (5) to inject a gaseous lining around the pulp, by break-up holes (3) for breaking up said pulp, and by rotation-imparting holes (4) in the vicinity of the outlet (1B) from the lance. The invention is particularly applicable to feeding a boiler with coal powder.
