Zusammenfassung:	BELL ORIFICE PLATE FOR INSHOT COMBUSTION FURNACE A belled orifice inlet plate is provided for an induced draft combustion furnace heat exchanger of the type in which an inshot burner produces a hot gaseous combustion that is injected through an opening in the inlet plate into a combustion zone in the heat exchanger. The inlet plate has a flared collar that surrounds the opening at its periphery, and which extends a predetermined distance into the combustion zone. Preferably, the collar should have a depth on the order of one-quarter inch to one-half inch, and the flared portion should have a radius of curvature on the order of about one-quarter inch.
