Claims (2)

1. Кольцевая секционная печь для обжига углеродных блоков, содержащая множество камер (К1-Кп), в которые помещают углеродные блоки при выполнении процесса обжига и в которой во время этого процесса часть печи, содержащая минимальное число камер, разделена на зону предварительного нагрева (К3-К2), зону горения (К7-К14) и зону охлаждения (К8-К10), которые все вместе и в последовательном порядке следуют в печи, в которой горючие газы, образующиеся в ходе процесса, отсасывают из первой камеры (К2) в зоне предварительного нагрева по патрубку, соединенному с общим кольцевым трубопроводом (10), отличающаяся тем, что вентилятор противодавления (17) установлен в патрубке, соединенном с первой камерой (К1), для исключения притока побочного газа из первой камеры (К1), расположенной рядом с зоной предварительного нагрева.1. An annular sectional furnace for burning carbon blocks, containing many chambers (K1-Kp), in which carbon blocks are placed during the firing process and in which during this process the part of the furnace containing the minimum number of chambers is divided into a preheating zone (K3 -K2), a combustion zone (K7-K14) and a cooling zone (K8-K10), which all together and in a sequential order follow in the furnace, in which the combustible gases generated during the process are sucked from the first chamber (K2) in the zone preheating through a pipe connected with a common annular pipe (10), characterized in that the backpressure fan (17) is installed in the nozzle connected to the first chamber (K1) to prevent the influx of by-product gas from the first chamber (K1) located next to the preheating zone. 2. Печь по п. 1, отличающаяся тем, что вентилятором противодавления (17) управляют на базе перепада давления между частями А и В первой камеры с помощью частотного преобразователя. 2. The furnace according to claim 1, characterized in that the backpressure fan (17) is controlled on the basis of the differential pressure between parts A and B of the first chamber using a frequency converter.
