ABSTRACT:
A spray head suitable for spraying thickened colliery tailings onto a fluidized combustion bed includes a central aperture for the egress of gas directed towards and surrounded by an annular orifice for the discharge of the material to be sprayed. As the material issues forth in use from the orifice a gas flow from the central aperture impinges upon it to generate the spray the characteristics of which may be varied by altering the size and/or location of the central aperture. An annular aperture located around the orifice provides for the discharge of a gas in the form of a curtain which protects the head from excessive heat which might otherwise cause agglomeration of material on the head.
