  • Economizer water recirculation system for boiler exit gas temperature control in supercritical pressure boilers
    Patent number: 9696027
    Abstract: 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.

  • Splitter plate arrangement for a flue gas stack
    Patent number: 6394008
    Abstract: A splitter plate arrangement is provided for controlling the flow of flue gas in a vertical stack. The splitter plate arrangement 100 is operable to control the flow of flue gas in a vertical stack 128 having an annular entry 130 communicated with two inlets 126A, 126B which each communicate a respective one of the flue gas producers with the vertical stack 128. The inlets 126A, 126B are both disposed on a common inlet axis which bisects the annular entry 130 into two bisected halves, the two inlets 126A, 126B are oriented in opposition to one another such that the inlet flow 132 of flue gas through the inlet 126A flows in a direction opposite to the inlet flow 134 of flue gas through the inlet 126B. The splitter plate arrangement 100 includes a first splitter plate 136 and a second splitter plate 138.
