Abstract:
An improvement in a rotary regenerative air preheater having a cold axial end casing with an air inlet and a flue gas outlet and a hot axial end casing with a heated air outlet and a flue gas inlet and having hot end sector plates adjacent said hot axial end casing dividing said air preheater into a flue gas sector and at least one air sector and further having a rotor with hot end radially extending seals cooperating with said hot end sector plates to form seals between said sectors and wherein said hot end sector plates have inboard ends adjacent the center of said rotor and outboard ends adjacent the periphery of said rotor, said improvement comprising a rib attached to each of said hot end sector plates projecting toward said hot axial end casing from said sector plate and extending down the center of said sector plate from said inboard end to said outboard end and a static seal attached to said hot end axial end casing adjacent each one of said ribs and extending from said inboard end to said outboard end and sealingly engaging said rib thereby forming a seal between said sectors.
