Seeley, Andrew J.; Price, Duncan M.; Inlet assembly. GB Patent Application 2,533,293 December 15 (2014)

An inlet assembly for a burner and a method are disclosed. The inlet assembly comprises: an inlet nozzle defining an inlet aperture coupleable with an inlet conduit providing an effluent gas stream for treatment by the burner, a non-circular outlet aperture, and a nozzle bore extending along a longitudinal axis between the inlet aperture and the outlet aperture for conveying the effluent gas stream from the inlet aperture to the outlet aperture for delivery to the combustion chamber of the burner, the nozzle bore having an inlet portion extending from the inlet aperture and an outlet portion extending to the non-circular outlet aperture. In this way, the non-circular outlet aperture provides a non-circular effluent gas stream flow into the combustion chamber. The non-circular effluent gas flow enables a greater volume of effluent gas stream to be introduced into the combustion chamber whilst still achieving or exceeding the required levels of abatement. This is because a non-circular effluent gas stream provides a reduced distance along which diffusion and reaction needs to occur compared to that of an equivalent circular effluent gas stream. Hence, an increased volume of effluent gas stream can be abated, compared to that of an equivalent circular effluent gas stream.
