Abstract

"MéTODO E APARELHO PARA MISTURAR COMBUSTìVEL PARA DIMINUIR EMISSõES DE COMBUSTORES". A invenção refere-se a um combustor (16) para um motor de turbina a gás (10), que opera com uma alta eficiência de combustão e baixas emissões de monóxido de carbono, óxido nitroso e fumaça durante operações em potência baixa, intermediária e alta do motor, é descrito. O combustor inclui uma montagem de misturador (41), que inclui um misturador piloto (42) e um misturador principal (44). O misturador piloto inclui um injetor de combustível piloto (58), pelo menos um misturador (60), e um divisor de ar (70). O misturador principal se estende circunferencialmente em torno do misturador piloto e inclui vários orifícios de injeção de combustível (98) e um misturador de ar cónico (110), a montante dos orifícios de injeção de combustível. Durante a operação de potência do motor improdutiva, o misturador principal é isolado aerodinamicamente do misturador principal, e apenas ar é suprido ao misturador principal. Durante as operações em maior potência, o combustível é também suprido ao misturador principal, e o misturador cónico do misturador principal facilita a mistura combustível - ar radial e circunferencial, para proporcionar uma distribuição de combustível e ar substancialmente uniforme para combustão.
