(5k) СПОСОБ АВТОМАТИЧЕСКОГО РЕГУЛИРОВАНИЯ ПРОЦЕССА ОЧИСТКИ ПОВЕРХНОСТИ НАГРЕВА (5k) METHOD FOR AUTOMATIC REGULATION OF THE CLEANING PROCESS OF THE HEATING SURFACE
1one
Изобретение относитс к способам управлени процессом сажеобдувки в содорегенерационных агрегатах, широко примен емых на целлюлозно-бумажных и картонных комбинатах.This invention relates to methods for controlling the sootblowing process in soda recovery units widely used in pulp and paper and paperboard mills.
По основному авт. св. № 901727 известен способ автоматического регулировани процесса очистки поверхности нагрева котла путем измерени перепадов давлений и температур продуктов сгорани в поверхност х нагрева и изменени по командному сигналу количества пара, подаваемого на обдув поверхности нагрева, размещенной в газоходеAccording to the main author. St. No. 901727 a method is known for automatically controlling the process of cleaning the heating surface of a boiler by measuring the differential pressure and temperature of the combustion products in the heating surfaces and changing, by a command signal, the amount of steam supplied to the heating surface blown in the flue duct.
Недостатком известного способа вл етс отсутствие учета возмущений , наносимых изменени ми концентрации пыли в продуктах сгорани в газоходе, которое не позвол ет получить высокое качество управлени процессом.The disadvantage of this method is the lack of consideration of disturbances caused by changes in the concentration of dust in the combustion products in the flue, which does not allow obtaining high quality process control.
Целью изобретени вл етс повышение качества управлени процесКОТЛАThe aim of the invention is to improve the quality of process control.
СОМ сажеобдувки. в содорегенерационных агрегатах.Sootblowing COM. in sodoregeneration units.
.Поставленна цель достигаетс тем, что согласно способу автоматического регулировани процесса очистки поверхности нагрева котла дополнительно измер ют текущее значение перепада концентраций пыли в продуктах сгорани на входе и выходе поверхности нагрева и по измеренному The goal is achieved by the fact that, according to the method of automatic control of the cleaning process of the heating surface of the boiler, the current value of the dust concentration difference in the combustion products at the inlet and outlet of the heating surface and measured
10 сигналу воздействуют на количество пара, подаваемого на обдув поверхности нагрева.10, the signal is affected by the amount of steam supplied to the blowout of the heating surface.
На чертеже представлена схема, реализующа предлагаемый способ.The drawing shows the scheme that implements the proposed method.
