Abstract
In various aspects, a preheater, a directed flow chemical vapor infiltration/chemical vapor deposition (CVI/CVD) furnace, and/or an installation jig are described. In one example, a preheater includes a central inlet; a circuitous gas flow path downstream of the central inlet; a plenum section downstream of the circuitous gas flow path; and an outlet diffuser plate defining a plurality of apertures fluidly configured to couple the preheater to a furnace working zone, wherein the outlet diffuser plate is downstream of the plenum section, wherein the circuitous gas flow path is fluidly coupled to the plenum section by an outer circumferential slot opening.
