    摘要: La présente invention se rapporte à un procédé et à une porte-buse qui servent à régler le mélange de courants gazeux dans des réacteurs à lit fluidisé et des réacteurs à lit fluidisé en circulation. Dans ledit procédé, une partie de l'air de combustion est introduite dans une chambre de réacteur à travers des buses de fluidisation (11) disposées dans un porte-buse (4). De façon à améliorer l'aptitude au réglage d'un processus de combustion, la partie restante de l'air de combustion est selon la présente invention introduite à travers des buses (12) de diffusion de jets dirigés essentiellement verticalement, lesquelles sont disposées dans le porte-buse (4) et la pénétration verticale des jets d'air appliqués à travers les buses (12) de diffusion des jets est maintenue à une valeur essentiellement supérieure à la valeur de la pénétration verticale des jets d'air appliqués à travers les buses de fluidisation (11). Selon la présente invention, le porte-buse (4) comprend par conséquent, en plus des buses de fluidisation (11), des buses (12) de diffusion de jets dirigés essentiellement dans un sens vertical, buses dont le diamètre est plus grand, de préférence 5 à 20 fois, que le diamètre des buses de fluidisation (11) et dont le nombre est essentiellement inférieur au nombre des buses de fluidisation (11).

    摘要: Method of controlling the temperatures of an exothermic process carried out in a suspension of solids in a reactor system formed by a wind box (2), a vertical riser (5), which is essentially not cooled, a particle separator (6), at least one set of recycling channels (9), which are not cooled, and at least one cooled set of recycling channels (12). According to the invention, the flow of solids travelling through the recycling channel (9), which is no cooled, as adjusted based on the temperature difference (T2-T1) between the upper and lower parts of a riser (5), which is not cooled, and the flow of solids travelling through the heat exchanger (12) is adjusted based on the temperature (T1) of the lower part or the temperature (T2) of the upper part of the riser tube. The control of the riser temperature is thus exclusively based on the regenerative heat transfer of the solids returned from the heat exchangers. In order for the solids returning from the heat exchanger not to create too great a temperature difference in the riser tube, solids that are not cooled are also returned to the lower part of the riser chamber in accordance with the set point control of the temperature difference of the riser tube. As all the temperatures of the thermally insulated riser tube are between the temperatures of its lower and upper parts, a perfect temperature control of the reactor is achieved by means of the simple method according to the invention.

    摘要: The invention concerns a method and a regenerator for transferring heat from one flow to another. The method is based on recirculating a granular heat transfer material between the circulating fluidized bed reactors of the regenerator configuration (comprising only two circulating fluidized bed reactors (A) and (B) in the basic configuration), whereby a tendency toward temperature equalization of the flows participating in the heat transfer process by entering the different circulating fluidized bed reactors is attained. The equalization of the temperatures is controlled by adjusting the particle flows between the reactors. The mixing of the flows is prevented by directing the particles separated in cyclone chamber (5) of circulating fluidized bed reactor (A) primarily into channel (10), where the particles form a fixed bed layer. From the bottom part of the channel section (10), a particle flow of desired volume rate is controlled to move from circulating fluidized bed reactor (A) to the other circulating fluidized bed reactor (B). When the channel section (10) becomes full, the remaining portion of the particles separated in the cyclone (5) fall back into the circulating fluidized bed reactor (A). The situation and operation of reactor (B) is fully analogous.

    摘要: The invention concerns a circulating fluidized bed reactor based on a multi-inlet cyclone, comprising an elongated riser channel (5; 25), which has a lower portion (4; 24) and an upper portion, whereby solid matter and fluidization gas can be fed into the riser through the lower portion (4; 24). In the upper portion of the riser channel there is a a multi-inlet cyclone which comprises a separation chamber (7; 27), with a set of guide vanes (6; 26), an annular space (8; 28) connected to the separation chamber, an outlet (11; 31) and a return channel (10; 30). According to the invention, the set of guide vanes (6; 26) of the multi-inlet cyclone, the cyclone chamber (7; 27) and the annular space (8; 28) are annularly fitted about the riser channel (5; 25). Pursuant to the invention a solution having advantageous flow dynamics is obtained. The reactor can be used e.g. as a dryer or a steam boiler.
