Abstract

resumo patente de invenção: "dispositivo e método para reduzir fluxo de massa de ar para combustão com baixas emissões em intervalo extendido para turbinas a gás de eixo único". a presente invenção refere-se a um dispositivo para reduzir o fluxo de massa de ar através do compressor em um motor de turbina a gás de eixo único com um intervalo de operação estendido incluindo condições de carga parcial, para prover combustão de baixas emissões. o dispositivo inclui um ou mais injetores posicionados para injetar ar comprimido para a região de admissão do compressor. os injetores estão orientados para direcionar o ar comprimido, de forma tangencial à, e na mesma direção angular que a, direção de rotação para criar um turbilhão no fluxo de ar de admissão para o indutor do compressor. o dispositivo também inclui condutos em comunicação de fluxo entre o difusor do compressor e os injetores, uma ou mais válvulas operacionalmente conectadas para controlar o fluxo de ar comprimido a partir do difusor para os injetores, e um controlador operacionalmente conectado às válvulas para provocar o fluxo de ar comprimido para os injetores durante a operação em condições de carga parcial.
