A once-through steam generator of double-flue design has a first vertical gas flue (4) with ascending conduct of fuel gas. In this generator, the combustion chamber rear wall (7) is inclined inwards relatively to the combustion chamber (8) in an upper part region (11) and thereby forms, with the bottom (12) of the adjoining horizontal gas flue (5), a nose which projects into the combustion chamber (8). Some steam generator tubes (9C) of the lower part region (14) of the combustion chamber rear wall (7) are lead upwards, uninclined, as supports for the said rear wall, as far as a supporting structure (15) located outside the conduct of the fuel gas.
Un générateur de vapeur continu à double alimentation présente une première conduite verticale (4) d'alimentation en gaz, avec un flux ascendant de gaz chaud. Cet appareil est caractérisé en ce que la paroi arrière (7) de la chambre de combustion est inclinée entrante et forme ainsi, avec le fond (12) de l'alimentation de gaz horizontale contiguë, un nez s'avançant dans la chambre de combustion (8). En raison de leur fonction de support, quelques tubulures (9C) de la partie inférieure (14) de la paroi arrière (7) du générateur de vapeur se prolongent sans inclinaison vers le haut, jusqu'à une structure de support (5) située hors de la conduite de gaz chaud.
