Claims (1)

Реактор с циркулирующим псевдоожиженным слоем содержит наружные теплообменные устройства, подпитываемые за счет внутренней рециркуляции. Реактор с циркулирующим псевдоожиженным слоем, содержит нижнюю зону с решеткой псевдоожижения, вводы первичного и вторичного воздуха и подвод топлива, верхнюю зону, внутренние плотные псевдоожиженные слои вверху нижней зоны, отбирающие твердый материал от потоков внутренней рециркуляции реактора и направляющие его частично в наружные теплообменные устройства с плотным псевдоожиженным слоем, примыкающие к стенкам реактора на уровне внутренних псевдоожиженных слоев. Эти наружные теплообменные устройства после теплообмена с наружной текучей средой сбрасывают твердый материал в нижнюю зону. Реактор простой конструкции, преимуществом которого является использование наружных плотных псевдоожиженных слоев при сохранении классической конструкции нижней зоны.The circulating fluidized bed reactor contains external heat exchangers, fueled by internal recirculation. The circulating fluidized bed reactor contains a lower zone with a fluidization grid, primary and secondary air inlets and fuel supply, an upper zone, internal dense fluidized beds at the top of the lower zone, which take solid material away from the internal recirculation flows of the reactor and partially direct it to external heat exchangers with dense fluidized bed adjacent to the walls of the reactor at the level of the internal fluidized beds. These external heat exchangers, after heat exchange with the external fluid, discharge solid material into the lower zone. The reactor is of a simple design, the advantage of which is the use of external dense fluidized beds while maintaining the classic design of the lower zone.
