Abstract

Patente de Invenção: <B>"MéTODO E APARELHO PARA EXTINçãO A SECO DE COQUE"<D>. São fornecidos um método e um aparelho para a extinção a seco de coque, aonde o clínquer não se deposita mesmo quando um aperfeiçoamento na segurança e o aumento na quantidade de recuperação de calor são tentados pela injeção de ar em uma pré-câmara e assim queimando os gases combustíveis e o coque fino ou por medidas similares. A presente invenção fornece um método e um aparelho para a extinção a seco de coque; em que uma torre de extinção (1) que consiste em uma câmara de resfriamento (2) e uma pré-câmara (3) localizada acima dela é utilizada, o coque incandescente (9) é carregado na torre de extinção por cima, o calor sensível do dito coque incandescente é trocado dentro da câmara de resfriamento utilizando um gás inerte como um meio de troca de calor, e o calor é recuperado como vapor; cujo método é caracterizado pelo fato de injetar água ou vapor (26) juntamente com o ar (24) na pré-câmara (3) por cima. Qualquer uma ou ambas as quantidades de injeção de água ou vapor (26) e de ar (24) injetadas na pré-câmara são controladas de modo que a temperatura dentro da pré-câmara (3) seja mantida a 1.150°C ou mais baixa.Invention Patent: <B> "METHOD AND APPLIANCE FOR DRY COKE EXTINGUISHMENT" <D>. A method and apparatus are provided for the dry extinguishing of coke, where the clinker does not deposit even when an improvement in safety and an increase in the amount of heat recovery are attempted by injecting air into a pre-chamber and thus burning combustible gases and fine coke or similar measures. The present invention provides a method and an apparatus for the dry quenching of coke; where an extinguishing tower (1) consisting of a cooling chamber (2) and a pre-chamber (3) located above it is used, the incandescent coke (9) is loaded into the extinguishing tower from above, the heat The sensitive part of said incandescent coke is exchanged inside the cooling chamber using an inert gas as a heat exchange medium, and the heat is recovered as a vapor; whose method is characterized by the fact of injecting water or steam (26) together with air (24) in the pre-chamber (3) from above. Either or both of the water or steam (26) and air (24) injection amounts injected into the pre-chamber are controlled so that the temperature inside the pre-chamber (3) is maintained at 1,150 ° C or lower .
