Abstract

processo de combustão distribuído e queimador. durante a fase de injeção de aquecimento, de um jato de combustível e oxidante (oxidente combustível ou oxidante anelar envolvimento os circularmente cercavam combustível) a partir de um bico de combustível-oxidante ser queimado em um espaço de combustão. durante a transição da fase de aquecimento para uma fase de combustão distribuída, uma quantidade de uma porção secundária, quer do combustível ou oxidante injetado como um jato para dentro do espaço de combustão, enquanto a parte principal desse mesmo reagente a partir do bico de combustível-oxidante é diminuída. em algum momento durante a fase de transição, um jato de fluido de acionamento é injetado em um ângulo para o jato de reagentes a partir do bico de combustível-oxidante e/ou na direção do jato de a parte secundária do reagente. o jato de porções primárias de reagentes e/ou porção do reagente secundário é causado para ser dobrado/desviado para o outro dos dois jatos. o estadiamento da porção secundário do reagente é aumentado até um grau desejado de estadimento e início de uma fase de combustão distribuída é alcançado.
