摘要： A heat recovery steam generator (“HRSG”) includes a first casing having an interior enclosing at least one duct for gas to flow therein along a gas flow axis. Each duct is defined by duct defining members that are spaced apart from each other and extend into the interior of the first casing. A plurality of stiffening members are elongated along the gas flow axis. Each of the stiffening members are positioned between two of the duct defining members. The stiffening members and duct defining members have a substantially similar coefficient of thermal expansion.

摘要翻译： 热回收蒸汽发生器（“HRSG”）包括第一壳体，其具有封闭至少一个管道的内部，气体沿气体流动轴线流入其中。 每个管道由彼此间隔开并延伸到第一壳体的内部的管道限定构件限定。 多个加强构件沿着气体流动轴线是细长的。 每个加强构件都位于两个管道限定构件之间。 加强构件和管道限定构件具有基本相似的热膨胀系数。
