    摘要: Procédé pour générer de la vapeur à haute pression et haute température, au moyen d'un générateur de vapeur industriel à récepteur solaire (1), de puissance supérieure à 100 MW, comportant au moins les étapes successives suivantes :
    - un mélange eau-vapeur est généré dans l'évaporateur (2) par transfert de chaleur provenant d'un flux solaire incident sur l'évaporateur (2) ;
    - le mélange eau-vapeur est séparé en eau saturée et en vapeur saturée dans le ballon de séparation (4), la vapeur saturée ayant une pression supérieure à 160 bar ;
    - l'eau d'alimentation est injectée dans le ballon mélangeur (5) où elle est mélangée avec l'eau saturée provenant du ballon de séparation (4), l'eau mélangée retournant ensuite vers l'évaporateur (2) par le conduit (9) de retour muni de la pompe de circulation (3),

    de sorte que la température de l'eau mélangée entrant dans l'évaporateur (2) soit inférieure à la température de vapeur saturée, d'une valeur comprise entre 5 et 15°C.

    摘要: The invention relates to a steam generator (1) comprising a combustion chamber having a peripheral wall (2) formed at least partially from gas-proof, welded steam generator pipes, at least two additional inner walls (4, 8) formed at least partially from additional steam generator pipes which are arranged inside the combustion chamber, and said inner walls are connected one behind the other on the flow medium side by an intermediate collector (6). The aim of the invention is to provide a steam generator which has a particularly high service life and is particularly reliable. Said flow medium on the inlet (12) of the inner wall (4) upstream of the intermediate collector (6) has a lower temperature than that of the flow medium on an inlet (10) of the peripheral wall (2).

    摘要: The invention relates to a heat exchanger (100) for an interior space of a combustion plant, comprising a plurality of heat exchanger pipes (11) extending in parallel over a defined length range (H), which heat exchanger pipes are altogether surrounded by a refractory protective lining (20) over said length range. Between the heat exchanger pipes (11) and the protective lining (20), at least one intermediate space (30) is formed. The heat exchanger further comprises gas supply means for supplying a protective gas to the at least one intermediate space (30). Together with webs (12) that mechanically connecting the heat exchanging pipes, the heat exchanger pipes (11) form a pipe wall (10). The at least one intermediate space (30) between the heat exchanger pipes (11) and the protective lining (20) is formed on both sides of the pipe wall (10). The gas supply means comprise a gas distribution box (40) having at least one gas inlet opening (41) for the protective gas and a plurality of gas outlet openings (42), which terminate in the at least one intermediate space (30) between the heat exchanger pipes (11) and the protective lining (20).
