Abstract
A two stage kinetic energy spray device has a first stage first nozzle having a receiving end that receives a particulate stream, an injection end located axially to the first nozzle receiving end, the injection end receiving the particulate stream from the receiving end. A second stage has a second nozzle, the second nozzle having a gas receiving portion that receives an effluent gas, a convergent portion that is downstream from the gas receiving portion and a divergent portion that is downstream from the convergent portion, the convergent portion and the divergent portion meeting at a throat. The particle stream is accelerated to a first velocity in the first nozzle located within the second nozzle divergent portion The effluent gas is accelerated to a second velocity in the second nozzle. First nozzle injection end chevrons allow mixing of particulate and supersonic effluent streams prior to exiting the spray device.
