摘要:
Systems and methods for controlling the startup of a gas turbine are described. A gas discharge component may be configured to discharge gas from a compressor component associated with the gas turbine. A fuel control component may be configured to control a fuel flow provided to a combustor component associated with the gas turbine. A drive component may be configured to supply a rotational force to a shaft associated with the gas turbine. At least one control device may be configured to (i) direct the gas discharge component to discharge gas from the compressor component, (ii) direct the fuel control component to adjust the fuel flow, and (iii) direct the drive component to rotate the shaft.

L'invention concerne un système et un procédé de démarrage automatique des moteurs d'un aéronef bimoteur. Selon l'invention, lorsqu'un premier moteur est en mis en procédure de démarrage automatique par les pilotes de l'aéronef, ce dernier suit le cycle de démarrage classique en quatre phases. Le rotor de l'étage haute pression du second moteur est mis en rotation pendant une durée prédéterminée et à une vitesse sensiblement constante et inférieure à la valeur nominale durant le cycle de démarrage du premier moteur. Une fois que le cycle de démarrage du premier moteur est terminé, le second moteur est mis en procédure de démarrage automatique par les pilotes de l'aéronef. Le cycle de démarrage du second moteur comprend uniquement trois phases.

In one embodiment, a system is provided. The system includes a turbine control system 12, 62, 64, 65, comprising a processor 66. The processor 66 is configured to receive an input for transitioning between a normal load path (NLP) 100 of a turbine system 10 and a cold load path (CLP) 102 of the turbine system 10. The processor 66 is additionally configured to determine a carbon monoxide (CO) setpoint based on the input. The processor 66 is further configured to apply a temperature control based on the CO setpoint, wherein the normal load path 100 comprises higher emissions temperatures as compared to the cold load path 102.

A combustor of a jet engine includes a fuel injector, an igniter for igniting a gas mixture of air and fuel, and a flame holder. The igniter is disposed in the flame holder. After an activation of the igniter, the igniter disappears, and a space after the disappearance functions as a flame-holding space.

A system for discharging compressed air from a compressor 16 includes an air distribution manifold 104 that is in fluid communication with the compressor via a conduit 102 and at least one discharge line 106 that is in fluid communication with the air distribution manifold. The discharge line defines a flow path from the air distribution manifold to atmosphere. The discharge line comprises a coupling pipe 110 that is coupled to the air distribution manifold, a sparger section 108 that is disposed downstream from the coupling pipe and at least one restrictor plate 114 that is disposed between the coupling pipe and the sparger section within the flow path. The restrictor plate comprises at least one aperture that provides a pressure drop of the compressed air between the air distribution manifold and the sparger section.
