Abstract
A modular type heat recovery steam generator (HRSG) utilizes multiple pairs of parallel offset upper headers and into which at least two rows of vertically-oriented tubes are connected also to a lower header. The upper headers in each pair are offset from each other by a distance equal to the overall width of up to four rows of tubes, and the tubes connected to each header of the pair are located on opposite sides of the headers. Also, the adjacent end of each header pair overlap each other by a distance equal 0.5-2 times the spacing between adjacent tubes. The header arrangement and tube configuration of each module provides a generator assembly which is compact and facilitates fabrication and installation of the modular generator assembly.
