Abstract
bico de injeção de iniciador um bico de injeção de iniciador para misturar um iniciador com um fluido de processo, compreendendo: um corpo compreendendo um orifício de entrada para receber o fluido de processo, um orifício de saída, e uma entrada de injetor para receber iniciador; uma passagem de fluxo de fluido de processo através da qual o fluido de processo atravessa entre o orifício de entrada e o orifício de saída ao longo de um eixo central de fluxo de processo, compreendendo ainda uma porção de constrição, uma garganta, e uma porção de expansão naquela ordem; uma passagem de fluxo de fluido iniciador através da qual o iniciador atravessa entre a entrada de injetor e a saída de injetor ao longo de um eixo central vertical de injetor, onde a passagem de fluxo de fluido iniciador, intercepta a passagem de fluxo de fluido de processo na porção de constrição; um ponteiro contendo pelo menos parcialmente a passagem de fluxo de fluido iniciador e compreendendo ainda uma ponta de injetor conformada formando a saída de injetor da passagem de fluxo de fluido iniciador; onde a saída de injetor se localiza na porção de constrição da passagem de fluxo de fluido de processo e a montante da garganta por um deslocamento horizontal determinado ao longo do eixo central de fluxo de processo; e onde a saída de injetor se localiza fora do eixo central de fluxo de processo por um deslocamento vertical determinado ao longo do eixo vertical central de injetor.
