ABSTRACT:
A multiple-jet orifice for the gas burner of a directly fired air heater of the non-premix type. The orifice openings are formed by radial slots in the periphery of a thin metal disc clamped between the end of a gas inlet pipe and a thicker metal disc member of special configuration. This specially configured disc member is larger in diameter than the gas inlet pipe and also larger in diameter than the slotted orifice disc. The portion of the member which is in contact with the slotted orifice disc is flat while the portion of the member larger than the slotted orifice disc is contoured outwardly in a convex manner. This convex surface by means of the Coanda effect causes the gas jets as emitted from the slotted orifice disc to flow into a conical shaped pattern and promotes the mixing of the gas with air and recirculated products of combustion.
