ABSTRACT:
A noise reducing heat exchanger assembly for a combustion system is disclosed. The heat exchanger assembly includes a plurality of side by side heat exchangers each having a single inlet for an inshot burner. An auxiliary port is located just above each burner inlet. A coupling chamber may be used to interconnect the auxiliary ports to allow acoustical coupling between the heat exchangers and to substantially prevent potential fluid flow between the heat exchangers and the surroundings of the combustion system. This heat exchanger assembly is particularly suitable for use as part of an induced draft combustion furnace.
