Title (EN) OXYGEN GAS ANALYZER
(FR) ANALYSEUR D"OXYGENE GAZEUX
Abstract: front page image
(EN)In an apparatus for analyzing gas collected directly in a flue by a gas collecting tube (1) projected from a wall surface (7) forming the flue, this being performed by means of a solid electrolytic oxygen gas analyzer, there is provided a separating plate (3) for partitioning the flue into gas inlet and outlet passages from the projected tip of the gas collecting tube (1) into the interior of the collecting tube (1) in the flue, the solid electrolytic oxygen gas analyzer being contained in a protecting tube (12) which is arranged within the gas collecting tube (1) Thus, the gas flowing in the flue flows by the dynamic pressure thereof from the inlet passage into the gas collecting tube (1) through the solid electrolytic oxygen gas analyzer located in the protecting tube (12), and then flows back at the separating plate (3) through the outlet passage to the flue. Accordingly, no power source is necessary for gas collection, and since there is no conduit having temperature gradient midway along its length, there is no possibility of drain production.
(FR)Dans un appareil d"analyse de gaz recupere directement dans une gaine de fumee par un tube de recuperation de gaz (1) se projetant a partir d"une surface d"une paroi (7) formant la gaine, a l"aide d"un analyseur electrolytique solide d"oxygene gazeux, un tube de separation (3) est prevu pour diviser la gaine en passages d"entree et de sortie de gaz provenant de l"extremite en saillie du tube de recuperation de gaz (1) vers l"interieur du tube de recuperation (1) dans la gaine, l"analyseur electrolytique etant contenu dans un tube de protection (12) qui est dispose dans le tube de recuperation de gaz (1). Ainsi, le gaz s"ecoule dans la gaine par sa pression dynamique a partir du passage d"entree dans le tube de recuperation de gaz (1) au travers de l"analyseur electrolytique situe dans le tube de protection (12), puis retourne au niveau de la plaque de separation (3) au travers du passage de sortie vers la gaine. De cette maniere, aucune source d"energie n"est necessaire pour la recuperation de gaz, et etant donne qu"il n"y a pas de conduite ayant un gradient de temperature a mi-chemin sur sa longueur, il n"y a pas de fuite possible.
