Description
Способ регулировани температуры перегретого пара пр моточного котла вспрыска питательной воды .в паровод ной тракт известен. В предлагаемом способе регучп-фовани температуры перегретого пара, с целью поддержани посто нства температуры пара за переходной зоной, стабилизации точки конца испарени в переходной зоне п уменьшени колебани температуры перегретого пара, выдаваемого котлом применен второй, посто нно действующий вспрыск питательной воды, осхчцеств.т емый до переходкой зоны котла. Дл ,ествлени этого вспрыска применены два трсхи.мпульспые и адин однонмпульсный рег /л тора , а также регул тор питательной воды и дифференциальный регул тор.The method of controlling the temperature of superheated steam of a continuous flow boiler of feedwater injection into the steam path is known. In the proposed method, the temperature of the superheated steam is controlled to maintain the temperature of the steam behind the transition zone, to stabilize the evaporation end point in the transition zone and to reduce the temperature fluctuations of the superheated steam produced by the boiler, a second constant injection of feed water is used, the maximum before the transition zone of the boiler. For this injection, two three-pulse and one-pulse reg / l torus, as well as a feedwater regulator and a differential regulator were used.
На чертеже изображеиа схема установки д.ч осуп.ествлени этого способа.In the drawing, an installation diagram of the installation should be used to investigate this method.
Дл осуществлени вспрыска в начале переходной зоны в схеме котла предусмотрена установка, состо ща из двух и трехимпульсных и саного однои.мпульского регул торов /, 2 и ,, регу.ч тора 4 питательной воды и дифференциального регул тора 5. Кроме того, имеютс четыре регулируюи их клапана 6, 7, 8 и 9. Питание котла осуществл етс центробежным насосом 10.In order to carry out the injection at the beginning of the transition zone, a setup is provided in the boiler circuit consisting of two and three pulses and one single pulse regulators I, 2, and feed water level adjuster 4 and differential regulator 5. In addition, there are four adjusting their valves 6, 7, 8 and 9. The boiler is powered by a centrifugal pump 10.
Регулирование вспрыска в схе.ме по предлагаемому способу осуществл етс следующим образом.The injection control in the scheme according to the proposed method is carried out as follows.
При изменении температуры пара за переходной sonoii регул тор 3 воздействует на регулирующий клапан 6 вспрыска. Вследствие изменени по.чожени клапана 6 перепад давлени на регулирующем питательном клапане 8 измен етс и в действие ветунает дифференциальный регул тор 5, который, ьоздейетву на регулирующий клапан .9, восстанавливает перепад давлени на регулирующем клапане 8. В результате суммарный расход питательной воды, подаваемой наеосом 10 через клапан .9, измен етс , а расход через клапан 8 сохран етс прежним. РазWhen the temperature of the steam behind the transitional sonoii controller 3 changes, it acts on the injection control valve 6. Due to the change in the valve pressure across the valve 6, the differential pressure on the control feed valve 8 is changed and a differential regulator 5 is actuated, which, on the control valve .9, restores the pressure differential on the control valve 8. As a result, the total flow rate of feed water supplied via the valve 10 through the valve .9, it changes, and the flow through the valve 8 remains the same. Time
