Abstract

"CâMARA DE COMBUSTãO/REFRIGERAçãO VENTURI PARA COMBUSTOR DE EMISSãO NOX BAIXA". Método e aparelho para fornecimento de ar refrigerante para o Venturi (11) e para a câmara de combustão (13) em um combustor (10) de emissão Nox baixa como utilizado em um motor de turbina de gás que inclui fornecimento de uma passagem de ar anular (14) circundando a câmara de combustão/Venturi próxima da parte traseira da câmara de combustão (13), escoando ar ao longo da câmara de combustão (13), passando pelo Venturi (11) onde tem uma saída de ar (28) próxima a parte frontal da área convergente do Venturi (11). O ar refrigerante é aquecido assim que passa pela câmara de combustão (13) e o Venturi (11), e então é diretamente direcionado para a parte traseira da câmara de mistura prévia (12) aperfeiçoando a eficiência do combustor (10) enquanto reduz a emissão Nox no processo de combustão.
