Description
привода печи,одновременно с измерением активного тока главного привода печи и температуры в зоне декарбонизации измер ют количество клинкера на выходе печи, после чего определ ют отношение суммы сигналов, пропорциональных величине активного тока главного привода печи и температуре в зоне декарбонизации, к сигналу, пропорциональному количеству клинкер на выходе печи, вычисл ют разность ме щу текущим значением полученного отношени и заданньам его значением и измен ют скорость вращени печи до достижени вычисленной разностью нулевого значени .the furnace drive, while measuring the active current of the main drive of the furnace and the temperature in the decarbonization zone, measure the amount of clinker at the kiln outlet, then determine the ratio of the sum of signals proportional to the active current of the main drive of the furnace and the temperature in the decarbonization zone to a signal proportional to the number clinker at the exit of the furnace, calculate the difference of the displacement by the current value of the ratio obtained and its specified value and change the speed of rotation of the furnace until the calculated difference of zero new value.
Способ осуществл етс следующим образом.The method is carried out as follows.
Количество отход щих газов поддерживают неизменным путем стабилизации разрежени в разгрузочном конце печи и после теплообменника. При стабилизированном количестве отход щих газов температура в зоне декарбонизации однозначно характеризует количество тепла,,поступающего из печи в теплообменник. Дл того, чтобы удельное количество тепла , идущего на нагрев сырь оставалось посто нным, стабилизируют отношение между количеством поступающего сырь и температурой в зоне подготовки .The amount of waste gases is maintained unchanged by stabilizing the vacuum in the discharge end of the furnace and after the heat exchanger. With a stabilized amount of waste gases, the temperature in the decarbonization zone uniquely characterizes the amount of heat coming from the furnace to the heat exchanger. In order for the specific amount of heat going to heat the raw material to remain constant, stabilize the ratio between the amount of incoming raw material and the temperature in the preparation zone.
Стабилизаци температуры первичного воздуха обеспечивает требуемую форму факела и уменьшает колебани температурного пол печи. Подачу топлива осуществл ют по разности между температурой газов в зоне декарбонизации и количеством топлива, корректиру расход топлива в зависимости от характеристики материала, в зоне спекани - по активной составл ющей тока главного привода печи, непрерывно измер количество клинкера ., выход щего из печи и форму отношение суммы двух сигналов - сигнала пропорционального активной составл ющей тока главного привода печи и сигнала, пропорционального величине температуры в зоне декарбонизации к измеренному количеству клинкера на выходе печи, определ ют разность между текущим значением указанного отношени и его заданным значением. По величине этой разности измен ют скорость вращени печи, регулиру этим врем нахождени ма .териала в печи и добива сь снижени удельного расхода тепла.Stabilizing the temperature of the primary air provides the desired shape of the torch and reduces fluctuations in the temperature field of the furnace. The fuel is supplied by the difference between the temperature of the gases in the decarbonization zone and the amount of fuel, the fuel consumption is adjusted depending on the material characteristics, in the sintering zone by the active component of the furnace main drive, continuously measuring the amount of clinker leaving the furnace and the shape the ratio of the sum of two signals — a signal proportional to the active component of the main drive of the furnace and a signal proportional to the temperature in the decarbonization zone to the measured amount of clinker is not and at the outlet of the furnace, the difference between the current value of said ratio and its target value is determined. By the magnitude of this difference, the rotational speed of the furnace is changed, thereby regulating the residence time of the material in the furnace and achieving a reduction in the specific heat consumption.
