Endonezya\u2019da Al\u00fcminyumdan Gaz Giderme<\/strong><\/p>\n

Endonezya\u2019da Al\u00fcminyum Gaz Giderme: D\u00f6ner gaz giderme y\u00f6nteminde, d\u00f6nen bir \u015faft ve rotor \u00fczerinden inert veya kimyasal olarak inaktif bir gaz (argon, azot) ge\u00e7irilmektedir.<\/p>\n

D\u00f6nen \u015faft\u0131n enerjisi, \u00e7ok y\u00fcksek bir y\u00fczey alan\u0131-hacim oran\u0131 sa\u011flayan \u00e7ok say\u0131da ince kabarc\u0131\u011f\u0131n olu\u015fmas\u0131na neden olur.
\nGeni\u015f y\u00fczey alan\u0131, hidrojenin gaz kabarc\u0131klar\u0131na h\u0131zl\u0131 ve etkili bir \u015fekilde yay\u0131lmas\u0131n\u0131 sa\u011flar; bu da s\u0131v\u0131 ve gaz fazlar\u0131nda hidrojen aktivitesinin dengelenmesine yol a\u00e7ar.<\/p>\n

Endonezya\u2019daki D\u00f6ner Gaz Giderme Al\u00fcminyum Tesisi, ak\u0131 ile gaz giderme y\u00f6ntemine k\u0131yasla daha eksiksiz bir hidrojen giderimi sa\u011flar.

Endonezya\u2019daki D\u00f6ner Tip Al\u00fcminyum Gaz Giderme Tesisi, gaz giderme ve ak\u0131 ekleme i\u015flevlerini bir arada y\u00fcr\u00fctebilir.
