摘要： A method includes processing data associated with operation of equipment in an industrial process to repeatedly (i) identify one or more models that mathematically represent the operation of the equipment using training data and (ii) generate first indicators potentially identifying at least one specified condition of the equipment using evaluation data and the one or more models. The method also includes classifying the first indicators into multiple classes. The multiple classes include true positive indicators and false positive indicators. The true positive indicators identify that the equipment is suffering from the at least one specified condition. The false positive indicators identify that the equipment is not suffering from the at least one specified condition. The method further includes generating a notification indicating that the equipment is suffering from the at least one specified condition in response to one or more first indicators being classified into the class of true positive indicators.

摘要： This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, a gas valve assembly may include a valve body with one or more valves movable between an opened position and a closed position, one or more valve actuators configured to operate the valves, and one or more pressure sensors to sense a pressure within a fluid path of the valve assembly. A valve controller may receive a measure related to a sensed pressure from the one or more pressure sensor(s). The valve controller may compare the received measure related to the sensed pressure to an overpressure threshold. In the event the measure related to the sensed pressure surpasses the overpressure threshold value, the valve controller may be configured to provide a signal that indicates an overpressure event has occurred.

摘要： A system for reducing moisture in a burner pressure sensing line in a gas turbine engine. A water trap is mounted on the burner pressure sensing line with an inlet for receiving burner pressure air and an outlet for transferring burner pressure air to the sensor. A heat sink is positioned inside the water trap for condensing moisture contained in the burner pressure air. Finned tubes are used to passively control the temperature of the burner pressure line. A deadheaded chamber provides an alternative location for the moist air to condense when the gas is compressed at higher pressure.

摘要： The state of a flame in a gas turbine engine combustor is acoustically monitored using a dynamic pressure sensor within the combustor. A spectral pattern of a dynamic pressure sensor output signal from the sensor is compared with a characteristic frequency pattern that includes information about an acoustic pattern of the flame and information about acoustic signal canceling due to reflections within the combustor. The spectral pattern may also be compared with a characteristic frequency pattern including information about a flame-out condition in the combustor.
