Abstract
Изобретение относитс к цветной металлургии , в частности, к способам пуска печей кип щего сло дл обжига сульфидосодержащих материалов. Целью изобретени вл етс снижение ррасхода топлива. Огарок загружают в печь забрасывателем после включени горелок таким образом, что он проходит сквозь их плам . Затем слой прогревают, отключают горелки при температуре 850°С и загружают сырье.The invention relates to non-ferrous metallurgy, in particular, to methods for launching fluidized bed furnaces for calcining sulphide-containing materials. The aim of the invention is to reduce fuel consumption. The bite is loaded into the furnace by the spreader after the burners are turned on in such a way that it passes through their flames. Then the layer is heated, turn off the burner at a temperature of 850 ° C and load the raw material.
Description
Изобретение относитс к цветной металлургии, в частности к печам кип щего сло дл обжига сульфидосо- держа цих материалов, и может быть использовано дл пуска аналогичных печей в химической промышленности.The invention relates to non-ferrous metallurgy, in particular, fluidized bed furnaces for calcining sulphide-containing materials, and can be used for starting similar furnaces in the chemical industry.
Целью изобретени вл етс снижение расхода топлива.The aim of the invention is to reduce fuel consumption.
Способ-пуска печи кип щего сло дл обжига сульфидосодержащих материалов был опробован при пуске печи КС.The start-up of the fluidized bed furnace for burning sulphide-containing materials was tested at the start-up of the KS furnace.
В печи производилс обжиг цинковых концентратов. Производительность печи КС-1 при работе на нижнем пороге составл ет 250 т/сут, на верхнем 450 т/сут. Загрузка огарка в печь производилась через верхний питательный бункер по системе транспортеров через забрасыватель, скорость ленты которого до 20 м/с. В печь загружалиZinc concentrates were roasted in a kiln. The capacity of the KS-1 furnace when operating at the lower threshold is 250 tons / day, at the upper 450 tons / day. The calcine was loaded into the furnace through the upper feeding hopper through the conveyor system through the spreader, with a belt speed of up to 20 m / s. The furnace was loaded
65 т огарка. Питательный бункер оснащен шибером дл дозировани подаваемого в печь материала. Шибер был отрегулирован на 15 т/ч. Забрасыватель обеспечивает равномерное распределение материала по подине. На стенках печи установлены три газовых горелки с расходом газа 250 м /ч. Контроль температуры сло осуществл лс термопарами.65 tons of cinder. The feeding hopper is equipped with a slide for dispensing the material fed to the furnace. The gate was adjusted to 15 t / h. The spreader ensures an even distribution of material along the bottom. Three gas burners with a gas consumption of 250 m / h are installed on the furnace walls. The temperature of the layer was controlled by thermocouples.
В верхний питательный бункер загружали 65 т огарка. После включени горелок огарок загружалс в печь забрасывателем в течение 4,2 ч. По истечение этого времени температура огарка составл ла 340 С.65 tons of cinder were loaded into the upper nutrient bunker. After turning on the burners, the calcine was loaded into the furnace by the spreader for 4.2 hours. After this time, the candle was heated to 340 ° C.
В соответствии с инструкцией по подготовке к пуску и пуску печи КС-1 за это же врем (4,2 ч) температура огарка достигает 210 С.In accordance with the instructions for preparing for the start-up and start-up of the KS-1 furnace for the same time (4.2 hours), the calcine temperature reaches 210 C.
