Abstract: An exhaust duct assembly for conveying exhaust gases emanating from a combustion zone to atmosphere is disclosed. The assembly includes: an exhaust gas outlet for exhausting exhaust gas into the atmosphere; and an acoustic duct portion located upstream of the exhaust gas outlet, the acoustic duct portion having a peripheral wall defining a through-passage arranged and constructed to promote propagation of sound there-through. The acoustic duct portion has a length in a flow direction that is at least 50% of an average hydraulic diameter of the through-passage.

Abstract: A low density foam material and methods for making such, comprising self-assembled graphene oxide in foam is described having high performance acoustic absorption as well as increased moisture insulation and fire-retardant properties. The graphene oxide material is inserted or distributed within openings of open cell/pore foam material resulting in a novel foam material that has increased acoustic absorption properties.
