A heat recovery generator has a housing defining a horizontally oriented exhaust gas stream. The exhaust gas stream passes through a first heat recovery unit having horizontally oriented heat transfer tubes and forced circulation of a heat transfer fluid therethrough. The exhaust gas stream then is passed through an air pollution control assembly having a catalyst for reduction of exhaust emissions. The exhaust gas stream is subsequently passed through a second heat recovery steam generator having vertically oriented heat transfer tubes and natural circulation therethrough.

[ What is claimed is:] [1.] A heat recovery steam generator for use with the exhaust of a gas turbine comprising:a housing for receiving the exhaust of a gas turbine defining a generally horizontal exhaust flow path therethrough having an upstream direction and a downstream direction;a first heat recovery assembly in said housing and oriented across said exhaust flow path having generally horizontally oriented first heat transfer tubes and forced once-through circulation of a heat transfer fluid;an air pollution control assembly in said housing, oriented across said exhaust flow path and in the downstream direction from said first heat recovery unit, said air pollution control assembly comprising a catalyst for the reduction of exhaust emissions;a second heat recovery assembly in said housing, oriented across said exhaust flow path and in the downstream direction from said air pollution control assembly, having generally vertically oriented second heat transfer tubes for natural circulation of a heat transfer fluid.
