AbstractA 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.
