A fluid recirculation system includes an arrangement of a flow control valve located to receive a flow of fluid from an inlet. The system further comprises an economizer inlet mixing device located to receive the flow of hotter fluid from the arrangement of the flow control valve and from a cooler feedwater stream. An economizer inlet mixing device located upstream of an economizer in a supercritical pressure boiler includes a sparger assembly through which a flow of fluid from the waterwall outlet is received, an inlet through which a flow of fluid from a feed stream is received, and a wave breaker assembly through which an outlet stream from the economizer inlet mixing device is directed.

A splitter plate arrangement is provided for controlling the flow of flue gas in a vertical stack. The splitter plate arrangement is operable to control the flow of flue gas in a vertical stack having an annular entry communicated with two inlets A, B which each communicate a respective one of the flue gas producers with the vertical stack . The inlets A, B are both disposed on a common inlet axis which bisects the annular entry into two bisected halves, the two inlets A, B are oriented in opposition to one another such that the inlet flow of flue gas through the inlet A flows in a direction opposite to the inlet flow of flue gas through the inlet B. The splitter plate arrangement includes a first splitter plate and a second splitter plate . The first splitter plate extends radially inwardly from the inner surface of the vertical stack at generally the midpoint MDOT of one bisected half of the annular entry of the vertical stack on one respective side of the inlet axis A. The second splitter plate extends radially inwardly from the inner surface of the vertical stack at generally the midpoint MDOB of the other bisected half of the annular entry of the vertical stack on the other respective side of the inlet axis A.
