This patent describes apparatus for injecting atomized coal slurry fuel into an engine combustion chamber. It comprises: vortex nozzle means, having an annular chamber with a substantially central outlet port, of fluid supplied to the fuel inlet port, in a conical sheet pattern that breaks up to atomized spray; metering means for delivering pressurized metered charges of the coal slurry fuel to the fuel inlet port at a pressure that is on the order of approximately five thousand psi or less and is sufficient to produce the conical sheet pattern outut flow from the outlet port; vortex-inducing means for imparting a tangential flow component to the coal slurry fuel entering the annular chamber via the fuel inlet port; and mounting means for positioning the vortex nozzle means to issue the conical sheet pattern of coal slurry fuel from the outlet port into the engine combustion chamber.
