Description
Изобретение относитс к теплоэнергетике , в. частности к аатоматическому управлению процесса.горени .This invention relates to a power system, c. Particularly to the aatomatic control of the process of burning.
Известны способы авт-оматического управлени и контрол содержани горючих элементов в летучей золе котлоагрегата путем отсосу дымовых газов из газохода котлоагрёгата и отделени из них летуче ; золы с последующим отбором пробы 1.Methods are known to automatically control and control the content of combustible elements in the fly ash of a boiler unit by sucking off flue gases from the boiler duct and separating from them volatile; ash and subsequent sampling 1.
Однако данный способ автоматического контрол не позвол ет достигнут требуемой точности.However, this automatic control method does not achieve the required accuracy.
Цель изобретени - повышение точности контрол .The purpose of the invention is to improve the accuracy of control.
Поставленна цель достигаетс тем, что пробу золы дозируют по массе и определ ют в ней содержание горючих элементов методом дифференциально-термического анализа.This goal is achieved by the fact that the ash sample is metered by mass and the content of combustible elements in it is determined by differential thermal analysis.
При этом дозирование пробы осуществл ют дискретными порци ми 100300 мг.In this case, the dosing of the sample is carried out in discrete portions of 100300 mg.
Кроме того, пробу золы дожигают при 800-850 0.In addition, the ash sample is burned at 800-850 0.
На чертеже представлена блок-схема устройства, реализующа данный способ автоматического контрол .The drawing shows a block diagram of a device implementing this method of automatic control.
Устройство содержит заборник 1 уход щих газов, циклон 2, шлюз 3,The device contains an intake of 1 flue gases, a cyclone 2, a gateway 3,
весы 4, задатчик 5 массы, дифференциальный блок 6 термического анализа , датчик 7 теплового потока, выполненный в виде нескольких термопар , регистратор 8 и блок 9 управлени .scales 4, mass setting unit 5, differential thermal analysis unit 6, heat flow sensor 7 made in the form of several thermocouples, recorder 8 and control unit 9.
Устройство работает следующим образом.The device works as follows.
00
Заборник 1 сорместно с циклоном 2 подготавливает анализируемую золу дл определени в ней горючих элементов . Шлюз 3 пропускает на весы 4 строго определенную задатчиком 5 Intake 1 in conjunction with the cyclone 2 prepares the analyzed ashes for the determination of combustible elements in it. Gateway 3 passes on the scales 4 strictly defined by the setting device 5
5 массы порцию золы из циклона 2. Затем зола поступает в дифференциальный блок 6 термического анализа, где дожигаютс при 800-850 0 горючие в данной порции пробы. Тепловой эффект 5 mass portions of ash from the cyclone 2. Then the ash enters the differential block 6 of thermal analysis, where combustible in this portion of the sample is burned at 800-850 0. Heat effect
0 реакции измер ют датчики 7 теплового потока и регистрируют регистратором 8.0 reactions are measured by heat flux sensors 7 and recorded by a recorder 8.
Таким образом, за счет применени Thus, through the use of
5 дифференциально-термического метода измерени количества горючих применительно к летучей зэле котлоагрёгата повышаетс точность контрол содержани горючих элементов в летучей 5 differential thermal method for measuring the amount of combustible in relation to the volatile boiler unit increases the accuracy of control of the content of combustible elements in the volatile
0 золе котлоагрёгата.0 ash boiler.
