Claims (4)

1. Реактор с циркулирующим псевдоожиженным слоем, содержащий кожух топочного реактора, по меньшей мере частично ограниченный передней стенкой и задней стенкой, отстоящей от передней стенки, и нижней стенкой, соединенной между передней и задней стенками; средство для подачи первичного воздуха через нижнюю стенку, который предназначен для псевдоожижения циркулирующего слоя в кожухе топочного реактора; средство для рециркуляции слоя из верхней части кожуха топочного реактора назад в его нижнюю часть; и топочный экран для ограничения в кожухе топочного реактора по меньшей мере одной интегральной камеры повышенного давления вторичного воздуха, предназначенной для подачи вторичного воздуха в псевдоожиженный слой, выше нижней стенки, без физического разделения нижней и верхней частей кожуха топочного реактора на части, причем указанный топочный экран проходит по существу вертикально в кожухе топочного реактора и имеет множество сквозных отверстий для обеспечения возможности хорошей передачи газообразных и твердых веществ через него от одной стороны топочного экрана к другой между передней и задней частями кожуха топочного реактора как в верхней, так и в нижней, его частях.1. The reactor with a circulating fluidized bed containing a casing of the furnace reactor, at least partially bounded by a front wall and a rear wall spaced from the front wall, and a lower wall connected between the front and rear walls; means for supplying primary air through the bottom wall, which is designed to fluidize the circulating layer in the casing of the furnace reactor; means for recycling the layer from the upper part of the casing of the furnace reactor back to its lower part; and a furnace screen for restricting in the furnace case of the at least one integral secondary pressure increased chamber for supplying secondary air to the fluidized bed above the lower wall, without physically dividing the lower and upper parts of the furnace reactor casing into parts, said furnace screen extends essentially vertically in the furnace case of the reactor and has many through holes to allow good transmission of gaseous and solid substances through from one side of the screen to the other fuel between the front and rear parts of the reactor shell a flue in the upper and in the lower part thereof. 2. Реактор по п.1, в котором кожух топочного реактора содержит боковые стенки, причем по меньшей мере одна интегральная камера повышенного давления вторичного воздуха проходит между этими боковыми стенками. 2. The reactor according to claim 1, in which the casing of the furnace reactor contains side walls, and at least one integral chamber of the increased pressure of the secondary air passes between these side walls. 3. Реактор по п.2, содержащий промежуточные каналы, предназначенные для подачи воздуха, проходящие в вертикальном направлении из нижней части кожуха и сообщающиеся по меньшей мере с одной интегральной камерой повышенного давления вторичного воздуха. 3. The reactor according to claim 2, containing intermediate channels for supplying air, extending in the vertical direction from the lower part of the casing and communicating with at least one integral secondary pressure secondary chamber. 4. Реактор по п.1, в котором поперечное сечение по меньшей мере одной интегральной камеры повышенного давления вторичного воздуха и поперечное сечение промежуточных каналов, предназначенных для подачи воздуха, выбраны из группы конфигураций, содержащей квадратную, прямоугольную, овальную, круглую, эллиптическую и ромбовидную формы. 4. The reactor according to claim 1, in which the cross section of at least one integral chamber of the increased pressure of the secondary air and the cross section of the intermediate channels for supplying air are selected from the group of configurations containing square, rectangular, oval, round, elliptical and diamond-shaped forms.
