Abstract

Способ и ленточная агломерационная установка для непрерывного спекания и предварительного восстановления гранулированного минерального вещества. Установка включает ленточную агломерационную печь (1), соединительный канал (15, 16), который обеспечивает потоковое сообщение от нижнего выпускного газопровода (9, 10) к впускному газопроводу (13, 14) для пропускания по меньшей мере части газа, выходящего из зоны (II, III) нагрева/спекания, в зону (V, VI) охлаждения, газовый датчик (17, 18), который установлен в соединительном канале (15, 16) для определения состава газа, канал (19, 20) для поступления воздуха, который обеспечивает потоковое сообщение между нижним выпускным газопроводом (9, 10) и атмосферой, и клапан (21, 22) для поступления воздуха, который расположен в канале (19, 20) для поступления воздуха, для того чтобы открывать и закрывать потоковое сообщение. Для создания восстановительной атмосферы установлено регулирующее устройство (23) для наблюдения за составами газа, определенными с помощью газового датчика (17, 18), и, на основе этого, для регулирования клапана (21, 22) для поступления воздуха, для регулирования доступа воздуха из атмосферы в выпускной газопровод (9, 10), с целью регулирования содержания кислорода в газе, и/или для регулирования коэффициента расхода воздуха при горении в горелке (7), с целью регулирования содержания монооксида углерода в газе.Method and belt sintering plant for continuous sintering and preliminary reduction of granular mineral matter. The installation includes a belt sintering furnace (1), a connecting channel (15, 16), which provides flow communication from the lower outlet gas pipeline (9, 10) to the inlet gas pipeline (13, 14) for passing at least part of the gas leaving the zone ( II, III) heating / sintering, in the cooling zone (V, VI), a gas sensor (17, 18), which is installed in the connecting channel (15, 16) to determine the gas composition, a channel (19, 20) for air intake, which provides a flow communication between the lower outlet gas line (9, 10) and the atmosphere, and an air intake valve (21, 22), which is located in the air flow channel (19, 20) in order to open and close the flow communication. To create a reducing atmosphere, a regulating device (23) is installed to monitor the gas compositions determined by the gas sensor (17, 18), and, on the basis of this, to regulate the valve (21, 22) for air intake, to control air access from atmosphere in the exhaust gas pipeline (9, 10), in order to control the oxygen content in the gas, and / or to control the air flow rate during combustion in the burner (7), in order to control the carbon monoxide content in the gas.
