Title
(EN) SOOTBLOWER HAVING A NOZZLE WITH DEEP REACHING JETS AND EDGE CLEANING JETS
(FR) SOUFFLEUR DE SUIE COMPORTANT UNE BUSE AVEC DES JETS ATTEIGNANT LES PROFONDEURS ET DES JETS DE NETTOYAGE DE BORD
Abstract
(EN)
A sootblower having a nozzle that includes one or more deep reaching jets aligned with its respective platen bank to clean slag deposits inset from the leading edge of the platen bank. The nozzle also includes one or more edge cleaning jets substantially angled with respect to the platen bank for cleaning the leading edges of the platen bank. For most applications, the major axis of the sootblower is perpendicular to the major axis of its respective platen bank, resulting in a sootblower with a nozzle having angled and perpendicular jets, referred to as angled-perpendicular nozzles. The jet sizes are selected to balance the opposing components of force perpendicular to the sootblower to avoid the imposition of torque on the lance.
(FR)
La présente invention concerne un souffleur de suie comportant une buse comprenant un ou des jets atteignant les profondeurs avec sa batterie de plaques respective pour nettoyer des dépôts de scories encastrée depuis le bord d'attaque de la batterie de plaques. La buse comporte également un ou des jets de nettoyage de bord inclinés sensiblement par rapport à la batterie de plaques pour nettoyer les bords d'attaque de la batterie de plaques. Pour la majorité des applications, l'axe principal du souffleur de suie est perpendiculaire à l'axe principal de sa batterie de plaques respective, permettant d'obtenir un souffleur de suie avec une buse comportant des jets inclinés et perpendiculaires, désignés buses inclinées/perpendiculaires. Les dimensions des jets sont choisies pour équilibrer les composantes opposées de la force perpendiculaire au souffleur de suie pour éviter une imposition de couple sur la lance.
