Abstract

LOS BORDES SUPERIORES DE LOS BRAZOS (8,9,10), QUE SE EXTIENDEN ENTRE LAS BARRAS (1,2,3,4) COMBUSTIBLES DE UN ELEMENTO DE COMBUSTION, DISCURREN EN TIRAS (19,20), QUE SON RETORCIDAS CONTRA LOS BRAZOS CON UN ANGULO DE TORCEDURA, SIENDO PROPORCIONAL DE FORMA CRECIENE CON RESPECTO A SU EXTREMO. PREFERENTEMENTE LAS PARTES (25,26) DE LAS TIRAS SON RETORCIDAS DE FORMA FUERTE, DE MODO QUE SE DISPONEN VERTICALMENTE CON RESPECTO A LOS BRAZOS, Y PUEDEN SER SOLDADOS DE FORMA CORRESPONDIENTE A LOS BRAZOS VECINOS DE PARTES DE LAS TIRAS, Y LOS BRAZOS TRANSVERSALES FORMAN UNA REJILLA EN FORMA DE CUADRILATERO.
