Изобретение относитс к теплоэнерf-етике и может быть использовано дл управлени режимом работы сепарационного узла при растопке пр моточного парогенератора.The invention relates to heat energy and can be used to control the operation mode of the separation unit when firing the steam generator.
Известен способ регулировани сброса паровод ной среды из сепаратора , встроенного в тракт пр моточного котла, путем измерени температуры металла верха и низа горизонтального участка паропровода и изменени клапана сброса по разности измеренных сигналов ГОНедостатком способа вл етс то, что он может быть реализован только при наличии двухфазной среды после первой ступени нагрева, что может быть только при значительных забросах влаги из сепаратора в перегреватель . Из-за удаленности места замера от регулирующего органа, косвенный параметр обладает большой инерционностью .The known method of controlling the discharge of the steam-water medium from the separator integrated into the path of the flow boiler by measuring the temperature of the metal of the top and bottom of the horizontal section of the steam line and changing the relief valve based on the difference of the measured signals of the GONED method is that it can be realized only if there is a two-phase environment after the first stage of heating, which can only be with a significant intake of moisture from the separator to the superheater. Due to the remoteness of the measurement site from the regulatory authority, the indirect parameter has a large inertia.
Цель изобретени - снижение инерционности .The purpose of the invention is to reduce inertia.
Поставленна цель достигаетс тем, что измерение температур осущестал -. ют на входе в перйую после сепаратора поверхность нагрева.The goal is achieved by measuring temperature. are heated at the entrance to the first after the separator.
На чертеже представлена схема устройства, реализующего предлагаемый способ.The drawing shows a diagram of the device that implements the proposed method.
На регул тор 1 сброса паровод ной To the regulator 1 of the steam
10 среды из сепаратора 2, воздействующего на клапан 3 сброса, установленный на линии 4 сброса среды из сепаратора , поступают сигналы от термопар 5 и 6, измер ющих температуры металла 10 of the medium from the separator 2 acting on the discharge valve 3 installed on the line 4 of the discharge of the medium from the separator, signals from thermocouples 5 and 6 are received, measuring metal temperatures
ts верха и низа горизонтального участка паропровода 7 на входе в первую после сепаратора поверхность 8 нагрева.ts of the top and bottom of the horizontal section of the steam line 7 at the entrance to the first heating surface 8 after the separator.
Регулирование сброса паровод ной среды осуществл ют следующим обра30 зом.The regulation of the discharge of the steam-water medium is carried out as follows.
