ABSTRACT OF THE DISCLOSURE In order to be able to run a gas turbine engine with pulverized coal as fuel on an industrial basis an arrangement is provided for utilizing the energy contained in the bypass flow with the help of which the solid combustion particles in the combustible gas are removed prior to its entry to the gas turbine blading. If the engine is used for an aircraft this arrangement consists of a thrust nozzle (12) impinged upon by the bypass flow which augments the action of the main thrust nozzle (7). For use in a stationary power plant this arrangement consists of a heat exchanger in which the heat of the bypass flow is utilized. Thus no unused energy gets lost by way of the bypass flow, so that the heat exchanger need not be kept extremely small for enonomic reasons. The result is a well cleaned combustible gas and the blades of the gas turbine (5) are to a large extent protected from erosion caused by combustible residues.
