An evaporatorfor evaporating a liquid includes a plurality of harpsdisposed within a duct or chamber such that a heated fluid flow(e.g., heated gas or flue gas) passes through each successive row of harpsof the evaporator. Each of the harpsincludes a lower header, a plurality of lower tubes, an intermediate equalizing chamber, a plurality of upper tubes, and an upper header. The lower tubesare in fluid communication with the lower headerand extend upward vertically from the lower header. The upper ends of the lower tubesare in fluid communication with the equalizing chamber. The upper tubesare in fluid communication with the equalizing chamberand extend upward vertically from the equalizing chamber. The upper ends of the upper tubesare in fluid communication with the upper header

Continuous steam generator with equalizing chamber

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.

Flexible assembly of recuperator for combustion turbine exhaust

A steam generator is disclosed herein. The steam generator includes an inlet manifold, a discharge manifold, a heating gas duct, and at least one once-through heating area in the heating-gas duct. The once-through heating area is formed from multiple single-row header-and-tube assemblies. Each single-row header-and-tube assembly includes a plurality of steam generator tubes connected in parallel, an inlet header connected to the inlet manifold, and a discharge header connected to the discharge manifold. Each inlet header is connected to the inlet manifold by one of multiple first link pipes, and each discharge header is connected to the discharge manifold by one of multiple second link pipes. Each said steam generator tube of each of the single-row header-and-tube assemblies has an inside diameter that is less than an inside diameter of any of the first or second link pipes.
