Abstract
"SISTEMA E LANçA TERMALMENTE PROTEGIDA PARA REPARAR REFRATáRIO FIBROSO SOBRE PAREDES DE UM VASO DE PROCESSO A ALTA TEMPERATURA, E, MéTODO DE REPARAR UMA PAREDE REFRATáRIA FIBROSA DE UM VASO DE PROCESSO A ALTA TEMPERATURA". Sistemas (10) e métodos são providos, por meio dos quais material fibroso viscoso bombeável pode ser aplicado sobre superfícies de vasos de processo a alta temperatura (12) enquanto quente (ou seja, enquanto a, ou, próximo de altas temperaturas operacionais desses vasos de várias centenas a vários milhares de graus Fahrenheit). Mais especificamente, é provida uma lança (14, 30) tendo uma estrutura de bocal (14-5) em uma extremidade distal da mesma,e um sistema de bomba (18) para bombear um material fibroso refratário bombeável para o bocal (14-5). A lança (14) tem um comprimento suficiente para permitir que a mesma seja inserida no vaso de processo a alta temperatura (12), de modo que a estrutura e bocal (14-5) fique adjacente a uma área que precisa de reparo enquanto um operador segura uma extremidade proximal da mesma fora do vaso (12). No uso, a lança (14,30) é inserida no vaso de processo (12) enquanto o vaso de processo (12) está à, ou, próximo à temperatura operacional, de modo que a estrutura de bocal (14-5) fique posicionada adjacente a uma área da parede do vaso de processo que precisa de reparo e, assim, que a lança (14, 30) possa ser manipulada do exterior do vaso de processo (12) durante o reparo de sua parede. A manipulação da lança (14, 30) pelo lado de fora do vaso de processo fará com que, desse modo, o spray atomizado do material fibroso contate a parede do vaso de processo (12), reparando, desse modo, a mesma."SYSTEM AND LAUNCH THERMALLY PROTECTED TO REPAIR FIBROUS REFRACTORY ON WALLS OF A HIGH TEMPERATURE PROCESS VASE, AND METHOD OF REPAIRING A FIBROUS REFRACTORY WALL OF HIGH TEMPERATURE". Systems (10) and methods are provided whereby pumpable viscous fibrous material can be applied to process vessel surfaces at high temperature (12) while hot (ie, at or near high operating temperatures of such vessels). several hundred to several thousand degrees Fahrenheit). More specifically, a lance (14, 30) having a nozzle structure (14-5) is provided at a distal end thereof, and a pump system (18) for pumping a pumpable refractory fibrous material to the nozzle (14-30). 5). The boom (14) is of sufficient length to allow it to be inserted into the process vessel at high temperature (12) so that the frame and nozzle (14-5) is adjacent to an area that needs repair while a operator holds a proximal end of it outside the vessel (12). In use, the lance (14.30) is inserted into the process vessel (12) while the process vessel (12) is at or near operating temperature so that the nozzle structure (14-5) is positioned adjacent to an area of the process vessel wall that needs repair and thus the boom (14, 30) can be manipulated from outside the process vessel (12) during repair of its wall. Manipulation of the lance (14, 30) on the outside of the process vessel will thereby cause atomized spray of fibrous material to contact the process vessel wall (12), thereby repairing it.
