More Information
Summary:A heat recovery steam generator ('HRSG') (40), which is closely coupled to a gas turbine, includes a flow controls structural array (10) disposed upstream of the tubes (42) of the HRSG (40). The structural array (10) is formed of a plurality of grate-like panels (18) secured to horizontal supports (24) mounted to the support structure of the HRSG (40). The structural array (10) diffuses the high velocity exhaust stream (14) exiting the gas turbine and redistributes the gas flow evenly throughout the HRSG (40). The structural array (10) reduces wear and damage of the tubes (46).
