The invention concerns an installation for controlling the sealed condition of water-gas heat exchangers equipping an industrial furnace (1), said furnace (1) comprising at least as assembly formed by means (9, 10, 11, 9', 10', 11') extracting a hot gas present in a specific zone of said furnace (1), a water-gas heat exchanger (12, 12') designed to cool the hot gas and means (14, 15, 14', 15') for reintroducing said hot gas which has been cooled into a zone of said furnace (1) located downstream of said zone where said hot gas is extracted. The invention is characterised in that it comprises: means (16, 16', 22 31) for sampling said hot gas at points (A, A') each located upstream of an exchanger (12, 12') and two-way valves (18-21, 18'-21') enabling said sampling; means (17, 17', 27, 32) for sampling said hot gas which has been cooled at points (B, B') each located downstream of an exchanger (12, 12') and two-way valves (23-26, 23'-26') enabling said sampling; means (36, 42) for regulating the respective pressure levels of said hot gas and the hot gas which has been cooled downstream of said sampling means (16, 16', 22, 31, 17, 17', 27, 32); means, such as a three-way valve (45) and its outlet pipe (46), for selecting said hot gas or said hot gas which has been cooled and sending it into an hygrometer (49); and means (50) for restoring to the operator the results of the analyses carried out by the hygrometer (49) enabling him to compare the degree of humidity of said hot gas and said hot gas which has been cooled for each of the exchangers (12, 12').
L'invention concerne une installation de contrôle de l'étanchéité d'échangeurs de chaleur eau-gaz équipant un four industriel (1), ledit four (1) comprenant au moins un ensemble formé par des moyens (9, 10, 11, 9', 10', 11') d'extraction d'un gaz chaud présent dans une zone donnée dudit four (1), un échangeur de chaleur eau-gaz (12, 12') destiné à refroidir ledit gaz chaud et des moyens (14, 15, 14', 15') pour réintroduire ledit gaz chaud refroidi dans une zone dudit four (1) située en aval de ladite zone où a eu lieu l'extraction dudit gaz chaud, caractérisé en ce qu'elle comporte: des moyens (16, 16', 22, 31) de prélèvement dudit gaz chaud en des points (A, A') situés chacun en amont d'un échangeur (12, 12') et des vannes à deux voies (18-21, 18'-21') autorisant la réalisation de ce prélèvement; des moyens (17, 17', 27, 32) de prélèvement dudit gaz chaud refroidi en des points (B, B') situés chacun en aval d'un échangeur (12, 12') et des vannes à deux voies (23-26, 23'- 26') autorisant la réalisation de ce prélèvement; des moyens (36, 42) pour réguler les pressions respectives dudit gaz chaud et dudit gaz refroidi en aval desdits moyens de prélèvement (16, 16', 22, 31, 17, 17', 27, 32); des moyens, tels qu'une vanne à trois voies (45) et sa conduite de sortie (46), pour sélectionner ledit gaz chaud ou ledit gaz refroidi et l'envoyer dans un hygromètre (49); et des moyens (50) pour restituer à l'opérateur les résultats des analyses effectués par l'hygromètre (49) en lui permettant de comparer le degré d'humidité dudit gaz chaud et dudit gaz refroidi pour chacun des échangeurs (12, 12').
