Abstract

CHAUDIERE. ELLE COMPREND UN RESERVOIR ANNULAIRE POUR LE LIQUIDE A CHAUFFER COMPRENANT DES PAROIS CONCENTRIQUES INTERNE ET EXTERNE FAISANT FONCTION DE SURFACES D'ECHANGE DE CHALEUR, UNE CHAMBRE INTERNE ETANT FORMEE A L'INTERIEUR DE LADITE PAROI INTERNE, UNE ENVELOPPE EXTERNE ESPACEE DE CETTE DERNIERE ET L'ENTOURANT, UNE CHAMBRE EXTERNE ETANT FORMEE ENTRE LADITE ENVELOPPE EXTERNE ET LADITE PAROI EXTERNE, DES MOYENS POUR DIRIGER LES GAZ CHAUDS A TRAVERS LADITE CHAMBRE INTERNE ET ENSUITE A TRAVERS LADITE CHAMBRE EXTERNE, DES AILETTES ACCELERANT L'ECHANGE DE CHALEUR, DISPOSEES DANS LADITE CHAMBRE INTERNE EN RELATION DE CONDUCTION THERMIQUE AVEC LADITE PAROI INTERNE, LES AILETTES FORMANT UN TRAJET SINUEUX LE LONG DE LADITE PAROI INTERNE POUR LA CIRCULATION DES GAZ CHAUDS, CE PAR QUOI UNE TURBULENCE EST IMPARTIE AUX GAZ ET LES COUCHES LIMITES SUR LES AILETTES SONT BRISEES, DES MOYENS DISPOSES DANS LADITE CHAMBRE EXTERNE POUR DONNER AUX GAZ CHAUDS LA FORME DE JETS DIRIGES SUR LES SURFACES TRANSFERANT LA CHALEUR AU LIQUIDE.BOILER. IT INCLUDES AN ANNULAR TANK FOR THE LIQUID TO BE HEATED INCLUDING INTERNAL AND EXTERNAL CONCENTRIC WALLS ACTING AS HEAT EXCHANGE SURFACES, AN INTERNAL CHAMBER BEING FORMED INSIDE THE SAID INTERNAL WALL, AN EXTERNAL ENCLOSURE AND THE EXTERNAL SPACE. 'SURROUNDING, AN EXTERNAL CHAMBER BEING FORMED BETWEEN THE SAID EXTERNAL ENCLOSURE AND THE SAID EXTERNAL WALL, MEANS FOR DIRECTING THE HOT GAS THROUGH THE INTERNAL CHAMBER AND THEN THROUGH THE EXTERNAL CHAMBER, THROUGH THE CHAMBER THROUGH THE CHAMBER THROUGH THE CHAMBER, THROUGH THE CHAMBER, THROUGH THE CHAMBER, THROUGH THE CHAMBER INTERNAL IN RELATION OF THERMAL CONDUCTION WITH THE SAID INTERNAL WALL, THE FINS FORMING A SINUOUS PATH ALONG THE SAID INTERNAL WALL FOR THE CIRCULATION OF HOT GAS, THEREFORE A TURBULENCE IS UNPARALLED TO THE GAS AND THE LIMIT LAYERS ON THE FINS ARE BROKEN. MEANS AVAILABLE IN THE SAID EXTERNAL CHAMBER FOR GIVING THE HOT GASES THE FORM OF JETS DIRECTED ON THE SURFACES TRANSFERRING THE LIQUID HEAT.
