  • Publication number: 20200011242
    Abstract: A hybrid power plant system including a gas turbine system and a coal fired boiler system inputs high oxygen content gas turbine flue gas into the coal fired boiler system, said gas turbine flue gas also including carbon dioxide that is desired to be captured rather than released to the atmosphere. Oxygen in the gas turbine flue gas is consumed in the coal fired boiler, resulting in relatively low oxygen content boiler flue gas stream to be processed. Carbon dioxide, originally included in the gas turbine flue gas, is subsequently captured by the post combustion capture apparatus of the coal fired boiler system, along with carbon diode generated by the burning of coal. The supply of gas turbine flue gas which is input into the boiler system is controlled using dampers and/or fans by a controller based on an oxygen sensor measurement and one or more flow rate measurements.

    Abstract: A gas turbine engine includes a first tap connected to a compressor section to deliver air at a first pressure. A heat exchanger is downstream of the first tap. A cooling air valve selectively blocks flow of cooling air across the heat exchanger. A cooling compressor is downstream of the heat exchanger and pressurizes the air from the first tap to a greater second pressure. A shut off valve selectively stops flow of the air between the heat exchanger and the cooling compressor. A controller controls the cooling air valve, the shut off valve, and the cooling compressor such that the flow of the air is stopped between the heat exchanger and the cooling compressor only after the controller has stopped the cooling compressor. A monitoring system communicates with the controller and includes a pressure sensor and a temperature sensor downstream of the cooling compressor.

  • Publication number: 20200011258
    Abstract: A system is provided for automatically shutting down an engine in response to the engine operating while in an enclosed space to prevent dangers associated with carbon monoxide accumulating in the enclosed space. The engine has an oxygen sensor in its exhaust that is configured to detect oxygen in the exhaust or ambient. A controller can be programmed to shut down the engine based on a determination that the engine is operating in a confined or enclosed space by analyzing a rate of change of the oxygen content in the exhaust or ambient, and compares the rate to a threshold. The shutdown may be commanded if the rate exceeds the threshold. In some embodiments, the shutdown may additionally be in response to a temperature of the ambient air or intake air increasing, which furthers the confidence of the determination that the engine is operating in a confined or enclosed space.

  • Publication number: 20200011273
    Abstract: A gas turbine engine system has an engine core and a bypass duct. A fan drives the flow through the bypass duct. A bypass efficiency is defined as the efficiency of the fan compression of the bypass flow. The bypass efficiency is a function of the bypass flow rate at a given set of conditions. The fan bypass inlet mass flow rate at the reference operating point is appreciably higher than the mass flow rate through the bypass duct at the peak bypass efficiency at a given fan reference rotational speed and cruise conditions. This results in increased design flexibility and improved overall engine performance.

    Abstract: Disclosed is a method for managing the starting of a combustion engine of a hybrid drive system including a combustion engine and an electric machine, as well as a drive shaft, the electric machine producing torque to start the combustion engine and drive the drive shaft at least during an initial phase of the start. In a transient starting phase, the combustion engine drives the drive shaft and the electric machine is stopped. The electric machine is regulated, during the initial phase and transient phases, with a first engine speed setpoint. The transient phase begins when the drive shaft reaches the first engine speed setpoint and remains steady. Torque control produced by the electric machine during the transient starting phase being configured so that the electric machine is stopped as soon as the control determines that the torque produced by the electric machine is tending toward zero torque.

  • Publication number: 20200011282
    Abstract: A model formula representing the relationship between an error between a predetermined stopping position and an actually-stopped position of a vehicle indicating the result of an automatic stop control, which controls the vehicle to stop at the predetermined stopping position using running-condition parameters, and the running-condition parameters used for the automatic stop control is calculated via machine learning. A stopping error is estimated with respect to the next stopping position, at which the vehicle currently running is going to stop, according to the model formula which is calculated in the past. The changing parameter to be changed is specified among the running-condition parameters, and then the changing parameter used for the automatic stop control is updated with a correction value configured to correct the stopping error of the vehicle.
