Abstract

UN INTERCAMBIADOR DE CALOR DE CONDENSACIÓN COMPRENDE UNA CÁMARA DE COMBUSTIÓN, PROVISTA EN SU PARTE SUPERIOR CON UN ESPACIO PARA LA INSTALACIÓN DE UN QUEMADOR DE GAS DE PRE-MEZCLA. DICHO INTERCAMBIADOR DE CALOR COMPRENDE UN TIRO DE GAS DE COMBUSTIÓN, DELIMITADO POR PAREDES, ENTRE LAS CUALES HAY DOS PAREDES ENFRIADAS CON AGUA ENTRE LAS CUALES PUEDE FLUIR EL GAS DE COMBUSTIÓN. CADA UNA DE LAS PAREDES ENFRIADAS CON AGUA COMPRENDE CANALES PARA EL FLUJO DE AGUA. LA CÁMARA DE COMBUSTIÓN ESTÁ UNIDA EN SU PARTE SUPERIOR, AL MENOS EN PARTE, AL ESPACIO PROVISTO PARA EL QUEMADOR; EN SUS COSTADOS MEDIANTE UN GRUPO DE DOS PRIMERAS PAREDES DE LA CÁMARA DE COMBUSTIÓN OPUESTAS ENTRE SÍ; Y POR UN GRUPO DE DOS SEGUNDAS PAREDES DE COMBUSTIÓN OPUESTAS ENTRE SÍ; Y EN SU PARTE DEL FONDO MEDIANTE EL TIRO DE GAS DE COMBUSTIÓN. LAS PRIMERAS PAREDES DE LA CÁMARA DE COMBUSTIÓN ESTÁN PROVISTAS CON CANALES PARA EL FLUJO DE AGUA. LAS PRIMERAS PAREDES DE LA CÁMARA DE COMBUSTIÓN ESTÁN PROVISTAS COMO EXTENSIONES DE PAREDES ENFRIADAS CON AGUA QUE DELIMITAN EL TIRO DE GAS DE COMBUSTIÓN. LAS DOS PRIMERAS PAREDES DE LA CÁMARA DE COMBUSTIÓN COMPRENDEN CADA UNA DE ELLAS UN PRIMER SEGMENTO Y UN SEGUNDO SEGMENTO, UBICADOS DEBAJO DEL PRIMER SEGMENTO. LOS PRIMEROS SEGMENTOS SON CURVADOS, DE MODO TAL QUE LA SECCIÓN DE LA CÁMARA DE COMBUSTIÓN UNIDA POR LOS PRIMEROS SEGMENTOS SE ENSANCHE EN LA DIRECCIÓN DE FLUJO DE GAS DE COMBUSTIÓN DESCENDENTE. CADA UNO DE LOS DOS PRIMEROS SEGMENTOS ESTÁ PROVISTO CON CANALES PARA EL FLUJO DE AGUA. LOS SEGUNDOS SEGMENTOS SON CURVADOS DE MODO TAL QUE LA SECCIÓN DE LA CÁMARA DE COMBUSTIÓN UNIDA POR LOS SEGUNDOS SEGMENTOS SE ESTRECHE EN LA DIRECCIÓN DESCENDENTE DEL GAS DE COMBUSTIÓN. EL SEGUNDO SEGMENTO DE LAS PRIMERAS PAREDES DE LA CÁMARA DE COMBUSTIÓN COMPRENDE ALETAS LONGITUDINALES ALARGADAS EN LA DIRECCIÓN LEJOS DE LA PARTE SUPERIOR DE LA CÁMARA DE COMBUSTIÓN Y QUE SE EXTIENDEN HACIA LA CÁMARA DE COMBUSTIÓN. EL PRIMER SEGMENTO DE LAS PRIMERAS PAREDES DE LA CÁMARA DE COMBUSTIÓN ES LISO, LO CUAL QUIERE DECIR QUE NO COMPRENDE PROTUBERANCIAS QUE AUMENTAN EL INTERCAMBIO DE CALOR Y QUE SE EXTIENDEN EN LA CÁMARA DE COMBUSTIÓN.A CONDENSATION HEAT EXCHANGER INCLUDES A COMBUSTION CHAMBER, PROVIDED ON ITS TOP WITH A SPACE FOR THE INSTALLATION OF A PRE-MIX GAS BURNER. SUCH HEAT EXCHANGER INCLUDES A SHOT OF COMBUSTION GAS, DEFINED BY WALLS, BETWEEN WHICH THERE ARE TWO WALLS COOLED WITH WATER BETWEEN WHICH CAN COMBUSTION GAS. EACH OF THE WALLS COOLED WITH WATER INCLUDES CHANNELS FOR WATER FLOW. THE COMBUSTION CHAMBER IS UNITED IN ITS TOP, AT LEAST IN PART, TO THE SPACE PROVIDED FOR THE BURNER; IN ITS SIDES THROUGH A GROUP OF TWO FIRST WALLS OF THE CHAMBER OF COMBUSTION OPPOSED BETWEEN; AND FOR A GROUP OF TWO SECOND OPPOSITE COMBUSTION WALLS BETWEEN YES; AND IN ITS PART OF THE FUND THROUGH THE COMBUSTION GAS SHOT. THE FIRST WALLS OF THE COMBUSTION CHAMBER ARE PROVIDED WITH CHANNELS FOR WATER FLOW. THE FIRST WALLS OF THE COMBUSTION CHAMBER ARE PROVIDED AS EXTENSIONS OF WALLS COOLED WITH WATER THAT LIMIT THE FUEL GAS SHOT. THE FIRST TWO WALLS OF THE COMBUSTION CHAMBER INCLUDE EACH OF THEM A FIRST SEGMENT AND A SECOND SEGMENT, LOCATED BELOW THE FIRST SEGMENT. THE FIRST SEGMENTS ARE CURVED, SO THAT THE SECTION OF THE COMBUSTION CHAMBER JOINED BY THE FIRST SEGMENTS IS CLOSED IN THE DIRECTION OF DOWN FUEL GAS FLOW. EACH ONE OF THE FIRST TWO SEGMENTS IS PROVIDED WITH CHANNELS FOR WATER FLOW. THE SECOND SEGMENTS ARE CURVED SO THAT THE SECTION OF THE COMBUSTION CHAMBER JOINED BY THE SECOND SEGMENTS IS STRICTED IN THE DOWN DIRECTION OF THE COMBUSTION GAS. THE SECOND SEGMENT OF THE FIRST WALLS OF THE COMBUSTION CHAMBER INCLUDES LONGITUDINAL FINS ALARGATED IN THE DIRECTION AWAY FROM THE TOP OF THE COMBUSTION CHAMBER AND EXTENDING TOWARDS THE COMBUSTION CHAMBER. THE FIRST SEGMENT OF THE FIRST WALLS OF THE COMBUSTION CHAMBER IS SMOOTH, WHICH WANTS TO SAY THAT IT DOES NOT INCLUDE PROTUBERANCES THAT INCREASE THE HEAT EXCHANGE AND EXTENDED IN THE COMBUSTION CHAMBER.
