A pulse combustion energy system including a pulse combustor coupled to a processing tube for flowing material to be processed therethrough, the processing tube being coupled to a pair of cyclone collectors for receiving the material flowing therefrom. An optional recycling section is coupled to the cyclone collectors for flowing vapor from the cyclone collectors back to the upstream end of the processing tube. The pulse combustor includes a rotary valve, a combustion chamber, an inner tail pipe and an outer tail pipe. The combustion chamber and inner tail pipe are conical and tubular sections mounted in longitudinal compression, and the compressive forces are transmitted externally across the junction of the combustion chamber and tail pipe by a strongback assembly. The rotary valve includes first, second, and third closely adjacent cylinders defining an interior air chamber. The cylinders have radially oriented, substantially aligned apertures which define an air intake. Air passing from the air chamber into the combustion chamber passes through an annular passage which impedes air flow from the combustion chamber toward the air chamber to a greater extent than air flow from the air chamber to the combustion chamber. Control systems regulate the product feed rate, the system firing rate, the system flow rate, and the operating frequency of the pulse combustor.

A pulse combustor comprising: an elongated combustion tube having an upstream end and a downstream end; an oxidizer intake valve at the upstream end in fluid communication with the tube for supplying an oxidizer to the tube in the form of discrete pulses; means for modulating the operating frequency of the oxidizer pulses over a substantial range of frequencies other than the natural operating frequency of the pulse combustor; and means for adding fuel to the oxidizer pulses proximate the upstream end of the tube so that the fuel can be combusted to generate hot gas pulses which propagate through and exit from the tube at the downstream end, whereby the frequency of hot gas pulses can be varied with the modulating means over a substantial range of frequencies other than the natural operating frequency of the pulse combustor.
