Gray, R R; Marguth, V M

This patent describes a pulse jet combustion apparatus for the drying of particulate material of the type having: a combustion chamber having an air entry end, an exhaust end and a common longitudinal axis therebetween, an air inlet conduit coaxially connected to the air entry and thereof, a primary exhaust gas conduit coaxially connected to the exhaust end thereof and, a tailpipe coaxially connected to the end of the exhaust gas conduit for directing the exhaust gases past a locus of particulate material introduction and to a dried particulate receiving chamber. The improvements described here comprise: primary fuel nozzles mounted at the air entry end of the combustion chamber downstream of the air inlet conduit and positioned to direct combustible fuel to a common location on the longitudinal axis of the combustion chamber spaced a predetermined distance from the air entry end thereof.
