Les installations industrielles sont de plus en plus proches des zones urbaines et p\u00e9ri urbaines. Le niveau sonore doit faire partie des crit\u00e8res permettant l\u2019int\u00e9gration dans le paysage et l\u2019acceptation des riverains (comme l\u2019architecture, le renouvelable, le social, etc.). La pollution sonore est donc un enjeu majeur dans la conduite d\u2019un projet que ce soit en process industriel, en production d\u2019\u00e9nergie thermique ou \u00e9lectrique. La performance et la compacit\u00e9 accrue des g\u00e9n\u00e9rateurs ont contribu\u00e9 \u00e0 l\u2019augmentation des probl\u00e9matiques de bruits dans le voisinage d\u2019une installation. Il existe pourtant des solutions efficaces pour tout g\u00e9n\u00e9rateur : chaudi\u00e8re, turbine, moteur, ventilateur\u2026 Ces g\u00e9n\u00e9rateurs n\u00e9cessitent des traitements acoustiques diff\u00e9rents des solutions du commerce disponibles.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”Best Beans” _builder_version=”4.14.9″ background_color_gradient_direction=”90deg” custom_margin=”-2px|||||” custom_margin_tablet=”41px||||false|false” custom_margin_phone=”53px||||false|false” custom_margin_last_edited=”on|tablet” custom_padding=”0px|0px|0px|0px” global_colors_info=”{}”][et_pb_row column_structure=”1_2,1_2″ use_custom_gutter=”on” gutter_width=”1″ make_equal=”on” admin_label=”Best Beans Row” module_class=” et_pb_row_fullwidth” _builder_version=”4.14.9″ width=”100%” width_tablet=”100%” width_phone=”100%” width_last_edited=”on|desktop” max_width=”100%” max_width_tablet=”100%” max_width_phone=”100%” max_width_last_edited=”on|desktop” custom_margin=”|||” custom_padding=”0px|0px|1px|0px||” make_fullwidth=”on” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.14.9″ custom_padding=”100px|10%|100px|10%” custom_padding_tablet=”0px||0px||true|false” custom_padding_phone=”0px||0px||true|false” custom_padding_last_edited=”on|tablet” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text admin_label=”Tittle” _builder_version=”4.14.9″ text_font=”Montserrat||||||||” text_text_color=”#000000″ text_font_size=”18px” text_line_height=”1.8em” header_text_align=”center” header_3_font=”Montserrat|700|||||||” header_3_text_color=”#000000″ header_3_font_size=”34px” header_3_line_height=”1.5em” max_width=”600px” max_width_tablet=”” max_width_phone=”” max_width_last_edited=”on|phone” module_alignment=”left” custom_margin=”|||” locked=”off” global_colors_info=”{}”]

Dans un premier temps, la r\u00e9alisation d\u2019une \u00e9tude prenant en compte les contraintes du site et environnementales li\u00e9es \u00e0 l\u2019arr\u00eat\u00e9 du 23 janvier 1997<\/strong> est n\u00e9cessaire.<\/p>\n

Et, m\u00eame s\u2019il n\u2019existe pas de solution universelle dans le traitement du bruit<\/strong>, BEIRENS mise sur une ad\u00e9quation de technologies<\/strong> pour atteindre les performances souhait\u00e9es. Dans tous les cas, il est pr\u00e9f\u00e9rable de traiter les probl\u00e8mes de bruit d\u00e8s l\u2019avant-projet lorsque les moyens pour y pallier sont parfaitement ma\u00eetris\u00e9s. Ainsi, il faut disposer au plus t\u00f4t des \u00e9l\u00e9ments des constructeurs de g\u00e9n\u00e9rateurs (br\u00fbleurs, chaudi\u00e8res, ventilateurs, moteurs, turbines\u2026). En l\u2019absence de donn\u00e9es fiables, il faut r\u00e9server une place \u00e0 l\u2019implantation d\u2019un silencieux avec l\u2019accessibilit\u00e9 ad\u00e9quate. Le prix de ce mat\u00e9riel n\u2019est souvent pas le fait de sa fabrication mais celui de son implantation dans une installation non pr\u00e9vue \u00e0 cet effet. C\u2019est pourquoi un \u00e9chappement doit \u00eatre con\u00e7u d\u00e8s l\u2019origine, avec un traitement acoustique int\u00e9gr\u00e9 ou \u00abpr\u00eat\u00bb \u00e0 recevoir un traitement acoustique adapt\u00e9 apr\u00e8s la mise en route de l\u2019installation, suivant les r\u00e9sultats de l\u2019expertise sonore<\/strong>. D\u2019apr\u00e8s le spectre acoustique au refoulement du g\u00e9n\u00e9rateur il faut d\u00e9finir une combinaison de traitement acoustique pour atteindre l\u2019att\u00e9nuation n\u00e9cessaire combin\u00e9e \u00e0 un engagement sur les pertes de charges.<\/p>\n

On constate r\u00e9guli\u00e8rement que des r\u00e9glages sur les sources (br\u00fbleurs, ventilateurs) permettent d\u00e9j\u00e0 d\u2019obtenir des r\u00e9sultats significatifs et ainsi d\u2019optimiser le choix du traitement acoustique \u00e0 apporter. S\u2019appuyer sur un retour d\u2019exp\u00e9rience solide dans la dynamique des gaz, la vibration des structures et l\u2019acoustique.\n\n3.

Puis adapter les formes, les mat\u00e9riaux, la densit\u00e9 de l\u2019isolant acoustique et sa protection m\u00e9canique.\n\n4. Optimisation des pertes de charge<\/strong>\n\nD\u00e9finir des designs sp\u00e9cifiques (forme du casing bord d\u2019attaque, bord de fuite, c\u00f4ne d\u2019\u00e9coulement) afin de limiter au maximum les pertes de charge et ainsi optimiser le rendement de l\u2019installation.\n\n5.

L\u2019habillage d\u2019un silencieux peut \u00eatre r\u00e9alis\u00e9 en jaquette aluminium brut ou en acier inoxydable poli miroir. L\u2019ensemble peut \u00eatre recouvert d\u2019une peinture.\n\nAppliquer les fondamentaux acoustiques au m\u00e9tier de l\u2019\u00e9chappement industriel est un challenge quotidien pour lequel Beirens est reconnu au niveau Europ\u00e9en. Nous continuons \u00e0 faire de la recherche et d\u00e9veloppement pour trouver de nouvelles solutions. La derni\u00e8re en date est un silencieux standard et compact destin\u00e9 aux groupes \u00e9lectrog\u00e8nes de secours : efficacit\u00e9 large bande, compacit\u00e9 et \u00e9conomie !
