Abstract: A computer-implemented method is provided for detecting actionable transaction risks. The method includes grouping an inbound event related to a transaction with a target event group and determining an actionable group of events that are deemed high risk and a non-actionable group of non-actionable events that are deemed low risk. The method also includes evaluating the target event group relative to the actionable and non-actionable groups of events. This includes computing a first distance between the target event group and the non-actionable group and a second distance between the target event group and actionable group. The first distance is compared with the second distance to determine if the target event group, including the inbound event, is closer to the actionable group or to the nonactionable group.

Abstract: A method of suppressing steam production in a HRSG where a volume of feed water is diverted upstream bypassing a portion of the economizer and returning the volume of diverted feed water to a downstream portion of the economizer. A control logic circuit is used to manipulate a suppression control valve regulating the bypassed feed water, thereby reducing the temperature of water in the steam drum. Bypassing feed water flow into a downstream portion of an economizer reduces the steam production rate in the steam drum by increasing the evaporator approach temperature, permitting gas turbines to operate at base load even after an upgrade, by preventing the waste heat boiler from exceeding its rated capacity and pressure.

Abstract: A heat transfer panel, or multiple panels, utilized to absorbed heat from the turbine exhaust gas as part of the Rankin cycle which simultaneously distributes the exhaust gas through the waste heat boiler. The panel varies the gas flow characteristics across a transverse and longitudinal plane, thereby eliminating the need for a separate flow distribution device.
