Abstract

o método é usado para aperfeiçoar a eficiência de carga parcial em um motor de turbina a gás (1) que compreende um compressor (2), queimadores (3), uma turbina de alta pressão (4) e uma turbina de baixa pressão (5); compreende a etapa de operar o motor de turbina a gás regulando-se pelo menos: taxa de fluxo de massa de ar e temperatura de chama; a regulação é realizada controlando-se pelo menos: a taxa de fluxo de massa de ar fornecida à câmara de combustão a partir do compressor, e o número de queimadores operacionais, e a mudança na queda de entalpia entre a turbina de pressão alta e baixa para controlar a taxa de fluxo de massa de ar.
