Title (EN) BOILER FOR GENERATING HOT WATER OR STEAM
(FR) CHAUDIÈRE DE PRODUCTION D'EAU CHAUDE OU DE VAPEUR
Abstract:
(EN) A boiler for generating hot water or steam, which comprises a containment enclosure (2) which defines a heating chamber (3), which contains the water to be heated and which accommodates a furnace (5), which defines a combustion chamber (6) provided with a burner (7) provided with a combustion head (8) and a device (9) for premixing air and gas; the combustion chamber (6) is connected to a plurality of heat exchange tubes (11), which pass through the combustion chamber (3) and lead into an exhaust gas collection chamber (12) which is connected to a flue (13); the premixing device (9) comprises a mixer body (16) accommodated axially in an air supply duct (17) and having at least one gas delivery opening (19); means are furthermore provided which are adapted to create a lower pressure in the combustion chamber (6) with respect to the external ambient pressure.
(FR) L'invention concerne une chaudière destinée à produire de l'eau chaude ou de la vapeur, la chaudière comprenant une enceinte de confinement (2) définissant une chambre de chauffage (3) contenant l'eau à chauffer et logeant un four (5) définissant une chambre de combustion (6) munie d'un brûleur (7) doté d'une tête de combustion (8) et d'un dispositif (9) de prémélange d'air et de gaz ; la chambre de combustion (6) est reliée à une pluralité de tubes d'échange de chaleur (11) traversant la chambre de combustion (3) et menant à une chambre de collecte des gaz d'échappement (12) reliée à un carneau (13) ; le dispositif de prémélange (9) comprend un corps mélangeur (16) logé axialement dans un conduit d'alimentation en air (17) et comportant au moins une ouverture de distribution de gaz (19) ; des moyens sont conçus en outre pour créer une pression inférieure dans la chambre de combustion (6) par rapport à la pression ambiante externe.
