摘要： A system for material drying comprising a pulse combustor and an associated combustion chamber whereby a pulsating flow of hot gases are generated. A tail pipe is connected to the outlet of the combustion chamber for receiving the pulsating flow of hot gases and a material introduction chamber is connected at the outlet of the tail pipe. A drying chamber is connected at the outlet of the material introduction chamber. The hot pulse combustion exhaust gases are cooled to control the temperature of the gases issuing from the outlet of the tail pipe and entering the material introduction chamber. This control is accomplished with a cool air stream issuing into the pulse combustion mixing chamber along with the hot gases from the pulse combustion tail pipe for mixing with and cooling of the hot gases. A separate diluent air stream may be employed for contact with material issuing from the introduction chamber and passing into the drying chamber. This separate diluent air stream will urge material already present in the drying chamber away from the entry location of new material into the drying chamber. The tail pipe may be provided with an inlet end of restricted dimension to act as a venturi with respect to the pulsating stream of hot gases entering the tail pipe from the combustion chamber thereby increasing the sound levels measured at the pulse combustion discharge.
