ABSTRACT:
A fuel inlet assembly for a fuel reactor which has an inner shell mounted coaxially within an outer shell, which is closed at one axial end, the outer shell having an inlet for introducing combustion air into the annular space between the inner and outer shells, the other end of the inner shell being spaced from the inlet assembly which is mounted at the other end of the outer shell, the fuel inlet assembly including a base plate which is mountable on said other end of the outer shell, and having a fuel inlet aperture therein. A first frusto-conical inlet cone is mounted on the base plate to surround the fuel inlet aperture and a second frusto-conical inlet cone is mounted coaxially therewith by means of a plurality of circumferentially spaced vanes which extend in radial planes, the second cone overlapping the first cone, whereby a portion of the combustion air can flow through the annular space between the first and second inlet cones, with an axial component of velocity, to premix with the fuel entering at the first fuel inlet aperture.
