Abstract
A recuperator includes a heating gas duct; an inlet manifold; a discharge manifold; and a once-through heating area disposed in the heating-gas duct through which a heating gas flow is conducted. The once-through heating area is formed from a plurality of first single-row header-and-tube assemblies and a plurality of second single-row header-and-tube assemblies. Each of the plurality of first single-row header-and-tube assemblies including a plurality of first heat exchanger generator tubes is connected in parallel for a through flow of a flow medium therethrough and further includes an inlet header connected to the inlet manifold. Each of the plurality of second single-row header-and-tube assemblies including a plurality of second heat exchanger generator tubes is connected in parallel for a through flow of the flow medium therethrough from respective first heat exchanger generator tubes, and further includes a discharge header connected to the discharge manifold. Each of the inlet headers is connected to the inlet manifold via a respective at least one of a plurality of first link pipes and each of the discharge headers is connected to the discharge manifold via a respective at least one of a plurality of second link pipes. Each of the heat exchanger tubes of each of the first and second single-row header-and-tube assemblies have an inside diameter that is less than an inside diameter of any of the plurality of first and second link pipes.
