Abstract
LA INVENCION SE REFIERE A UN METODO DE INTRODUCCION DE GAS EN EL SENO DE UN LIQUIDO, EN EL QUE UNA CORRIENTE GASEOSA SE EXPULSA DESDE UNA LANZA A UNA DISTANCIA SOBRE LA SUPERFICIE LIQUIDA Y SE DIRIGE DESDE LA LANZA SOBRE DICHA SUPERFICIE. EL GAS CONSERVA PRACTICAMENTE TODA SU VELOCIDAD DE EJE DEL CHORRO ORIGINAL CUANDO CONTACTA CON LA SUPERFICIE DEL LIQUIDO Y PRACTICAMENTE LA TOTALIDAD DEL GAS PENETRA EN LA SUPERFICIE DEL LIQUIDO Y ES INTRODUCIDO EN SU SENO. PREFERIBLEMENTE LA CORRIENTE GASEOSA ESTA RODEADA POR UNA ENVUELTA DE LLAMA QUE DISCURRE DESDE LA LANZA HASTA LA SUPERFICIE DEL LIQUIDO, QUE PROTEGE EL GAS DEL ARRASTRE DEL GAS AMBIENTAL. LA CORRIENTE GASEOSA FORMA PREFERIBLEMENTE UNA CAVIDAD GASEOSA EN EL INTERIOR DEL LIQUIDO, CON UN DIAMETRO PRACTICAMENTE IGUAL AL DIAMETRO DE LA CORRIENTE GASEOSA TAL Y COMO ES EXPULSADA DESDE LA LANZA.
