Comme son nom l\u2019indique, dans un br\u00fbleur \u00e0 tube \u00e0 fum\u00e9e, le gaz d\u2019\u00e9chappement circule \u00e0 l\u2019int\u00e9rieur de tubes entour\u00e9s d\u2019un manteau d\u2019eau qui refroidit les tubes. Ces br\u00fbleurs sont g\u00e9n\u00e9ralement mont\u00e9s verticalement et disposent g\u00e9n\u00e9ralement de trois passages de tubes, avec entre 300 et 800 tubes \u00e0 l\u2019int\u00e9rieur du br\u00fbleur, allant du chaud au centre aux plus froids dans les parties ext\u00e9rieures.<\/strong><\/p>\n<p>Le nettoyage en ligne des chaudi\u00e8res \u00e0 tube \u00e0 fum\u00e9e est difficile et doit \u00eatre combin\u00e9 avec un nettoyage manuel. Les m\u00e9thodes de nettoyage traditionnelles comprennent l\u2019utilisation d\u2019air comprim\u00e9 provenant de la partie sup\u00e9rieure de la chaudi\u00e8re ainsi que le nettoyage manuel de chaque tube. Pour le nettoyage manuel, il faut d\u00e9brancher la chaudi\u00e8re de l\u2019alimentation \u00e9lectrique et, normalement, on utilise un chaudi\u00e8re \u00e0 fuel pour compenser la perte de production. Le nettoyage manuel est un travail dangereux qui peut prendre jusqu\u2019\u00e0 un jour et co\u00fbter \u00e0 la fois des heures de travail et la consommation d\u2019huile.<\/p>\n<p>Le plus souvent, la contamination d\u2019un br\u00fbleur \u00e0 tube \u00e0 fum\u00e9e commence dans la chambre de tourbillonnement, o\u00f9 il n\u2019y a pas de nettoyage automatique et o\u00f9 l\u2019air comprim\u00e9 aspir\u00e9 depuis le haut n\u2019atteint pas les tubes. Le m\u00e9canisme de contamination comprend l\u2019accumulation de ce qu\u2019on appelle des \u201c barbes \u201d \u00e0 l\u2019entr\u00e9e des tubes \u00e0 fum\u00e9e. \u00c0 mesure que ces barbes se d\u00e9veloppent, elles sont aspir\u00e9es dans les tubes et les obstruent finalement. Comme chaque tube repr\u00e9sente 0,5 % de la surface de transfert de chaleur du br\u00fbleur, la chaleur est rapidement perdue, entra\u00eenant des pertes d\u2019efficacit\u00e9 thermique. En utilisant des infrasons \u00e0 longue port\u00e9e, les tubes \u00e0 fum\u00e9e restent ouverts au fond, \u00e9vitant ces pertes et prolongant le temps entre les op\u00e9rations de nettoyage manuelles.<\/p>\n<div id=\"attachment_1614\" style=\"width: 898px\" class=\"wp-caption alignnone\"><img decoding=\"async\" aria-describedby=\"caption-attachment-1614\" class=\"wp-image-1614 size-full\" src=\"https:\/\/heatmanage.com\/wp-content\/uploads\/2021\/01\/Ska\u0308rmavbild-2021-01-07-kl.-14.26.45.png\" alt=\"Nettoyage du br\u00fbleur \u00e0 tube \u00e0 fum\u00e9e\" width=\"888\" height=\"852\" srcset=\"https:\/\/heatmanage.com\/wp-content\/uploads\/2021\/01\/Ska\u0308rmavbild-2021-01-07-kl.-14.26.45-200x192.png 200w, https:\/\/heatmanage.com\/wp-content\/uploads\/2021\/01\/Ska\u0308rmavbild-2021-01-07-kl.-14.26.45-300x288.png 300w, https:\/\/heatmanage.com\/wp-content\/uploads\/2021\/01\/Ska\u0308rmavbild-2021-01-07-kl.-14.26.45-400x384.png 400w, https:\/\/heatmanage.com\/wp-content\/uploads\/2021\/01\/Ska\u0308rmavbild-2021-01-07-kl.-14.26.45-600x576.png 600w, https:\/\/heatmanage.com\/wp-content\/uploads\/2021\/01\/Ska\u0308rmavbild-2021-01-07-kl.-14.26.45-768x737.png 768w, https:\/\/heatmanage.com\/wp-content\/uploads\/2021\/01\/Ska\u0308rmavbild-2021-01-07-kl.-14.26.45-800x768.png 800w, https:\/\/heatmanage.com\/wp-content\/uploads\/2021\/01\/Ska\u0308rmavbild-2021-01-07-kl.-14.26.45.png 888w\" sizes=\"(max-width: 888px) 100vw, 888px\" \/><p id=\"caption-attachment-1614\" class=\"wp-caption-text\">Figure 1.
