Abstract

L'invention appartient au domaine de la production d'énergie autonome et des installations à cogénération munies d'un moteur Stirling; elle sert à produire simultanément de l'énergie électrique et de la chaleur. Lors du fonctionnement, le moteur Stirling (1) produit de l'énergie utile convertible en énergie électrique au moyen d'un générateur électrique (2). Pour refroidir le moteur (1) on alimente dans sa chambre de refroidissement (18) à partir d'un système de refroidissement (3) un liquide de refroidissement qui transmet la chaleur du moteur Stirling à un système externe d'amenée de chaleur (7) ainsi que dans le milieu environnant au moyen d'échangeurs de chaleur (11) et (5). Pour assurer le fonctionnement du moteur Stirling le gaz de génération provenant d'un générateur (13) est envoyé via une conduite (14) dans une chambre de combustion (15). Pour brûler ce gaz, on injecte de l'air préalablement chauffé via une conduite (6). Les gaz usés provenant de la chambre de combustion (15) sont envoyés via une conduite (12) dans un échangeur de chaleur et récupérateur (8) de la chaleur des gaz usés, où ces gaz transmettent sa chaleur à un caloporteur du système d'amenée de chaleur externe (7). Pour augmenter la longévité du moteur Stirling et prolonger la durée de vie utile de la chambre de combustion (15), une partie des gaz usés est renvoyée via la conduite (16) dans la chambre de combustion (15), ce qui permet de réduire la température de combustion du mélange d'air et de gaz du générateur. Afin de réguler l'alimentation en gaz usés dans la chambre de combustion (15), on a monté sur la conduite (16) un robinet de réglage (17).
