ABSTRACT:
An improved burner nozzle and process for making a synthetic or fuel gas mixture containing hydrogen and carbon monoxide by the partial oxidation, in a free-flowing hollow reactor, of a slurry of solid carbonaceous fuel in a liquid carrier admixed with a gas containing free oxygen. The nozzle may also be used in other applications where nozzles are required to handle slurries having a high concentration of finely-divided solids that must be uniformly admixed with a gas, as for example, in the aeration or incineration processes of a waste disposal plant. The nozzle and process include enveloping of an annular slurry stream between a central layer and an annular layer of high velocity gas, impinging the annular slurry stream on a downstream nozzle diffuser where a zone of high shear forces produce a uniform atomized admixture of solids, liquids and gases, and then transporting the admixture through an exit orifice at an accelerated velocity to further atomize the admixture.
