Abstract
A turbulent flow injector includes a ceramic injector body having an outer ylindrical wall with an inner surface, an inner cylindrical wall having an inner surface, an end wall at an outlet end of the body terminating the outer and inner walls so as to define an annular cavity between the inner and outer walls. The annular cavity is open at an inlet end of the body. A duct, defined by the inner surface of the inner wall, has an inlet at the inlet end of the body. A heat conductive insert is positioned within the annular cavity and has an outer surface in thermal contact with the inner surface of the outer wall. The insert has an external section extending beyond the inlet end of the body and cooling fins extending from the external section. An annular air chamber is defined between the insert and the inner wall of the body. An important feature of the invention is a protuberance mounted at the inlet end of the body and radially extending over the inlet of the duct for inducing turbulent flow in a fluid flowing through the duct.
