Abstract (en)
[origin: GB2551165A] A burner has a primary conduit (13, fig.2) extending along a burner axis to a primary conduit outlet for conveying a mixture of fuel and primary gas (PA) and a secondary conduit (15, fig.2) disposed about the primary conduit extending parallel to a burner axis to a secondary conduit outlet for conveying a secondary gas (SA). A shroud comprising a shroud outlet plate (3, fig.2) is located at the burner outlet transverse to the burner axis, having a shroud central outlet (5, fig.2) and a plate formation extending outwardly from the central outlet over and beyond the primary and secondary conduit outlets. A primary flow divider (11, fig.2) is coupled to the shroud central outlet and divides the flow in the primary conduit between a first primary subflow (PA1) to the shroud central outlet and a second primary subflow (PA2) diverted away from the shroud central outlet. The burner may use pulverous fuel. The first primary subflow and the secondary gas may be deflected by the plate to leave the burner peripherally of the plate and form Reaction Zones 2 which may generate flue gas to produce an effect equivalent to flue gas recirculation and/or to enhance flue gas recirculation.
