Abstract

LANÇA DE INJEÇÃO DE SÓLIDOS. A presente invenção refere-se a um método para injetar um material de alimentação sólido através de uma lança de injeção de sólidos que inclui criar condições de fluxo em uma passagem de injeção da lança de modo que pelo menos uma parte do material de alimentação que flui ao longo da passagem forme uma zona de tampão entre uma parede de um tubo que define a passagem e o material de alimentação que flui ao longo de uma seção central da passagem.
