Description

Известные котлы обычно оборудуютс  поверхностными пароохладител ми , охлаждающим агентом дл  которых служит питательна  вода. После пароохладител  эта вода направл етс  через экономайзер в котел.Conventional boilers are usually equipped with surface desuperheaters for which feedwater serves as a cooling agent. After the desuperheater, this water is directed through an economizer to the boiler.

Основной недостаток наиболее распространенных схем включени  ар атуры дл  регулировани  уровн  воды в барабане котла и температуры нерегрева пара заключаетс  в том. что нри их нрименении изменение расхода воды, проход щей через пароохладитель, вызываемое необходимостью поддерживать заданную температуру перегрева, приводит к изменению уровн  воды в барабане котла или изменение общего расхода воды, подаваемой в котел, св занное с необходимостью удержать в заданных пределах ее уровень в котле, приводит к изменению температуры перегрева.The main disadvantage of the most common armature activation schemes for regulating the water level in the boiler drum and the temperature of the non-heating steam is. that, in their application, a change in the flow rate of water passing through the desuperheater, caused by the need to maintain a given superheat temperature, leads to a change in the water level in the boiler drum or a change in the total flow rate of water supplied to the boiler, due to the need to keep it , leads to a change in overheating temperature.

Применение предлагаемой схемы, изображенной на чертеже, исключает взаимное вли ние изменени  расхода воды, св занного с регулированием уровн  ее в барабане, и темнературы иерегрева нара. Это дости.гаетс  применением дифференциальных регул торов, поддерживающих посто нные перепады давлени  в питательном , и клапана, регулирующего температуру перегрева пара.The application of the proposed scheme shown in the drawing eliminates the mutual influence of changes in water flow associated with adjusting the level in the drum and the temperature of the heater. This is achieved by using differential regulators that maintain constant pressure drops in the feed and valve that regulates the steam superheat temperature.

Свойства рассматриваемой схемы не мен ютс  от того, осущ,еетвл етс  ли воздействие на регулирующую арматуру вручную или автоматически .The properties of the circuit in question do not vary depending on whether the effect on the control valve is performed manually or automatically.

Из схемы видно, что количество воды, нодводнмой в коте.ч, онредел етс  автоматическим регул тором уровн  {или водосмотром), воздействующим на регулирующий к.чанаи /. На фланнах этого клапана при помощи дифференциального регул тора 2 поддерживаетс  посто нный перепад давлени  (за счет изменени  открыти  клапана дифференциального регул тора). Таким образом, изменение расхода воды, проход щей через кланан I, зависит только от изменени  величины его открыти , завис щей, как указаио вьине, от работы регул тора уровн  (или водосмотра).It can be seen from the diagram that the amount of water, in water in the cat. H, is determined by the automatic level controller (or water inspection) acting on the control k.chanai /. On the flanges of this valve by means of the differential regulator 2, a constant pressure differential is maintained (by changing the opening of the valve of the differential regulator). Thus, the change in the flow rate of the water passing through the clanan I depends only on the change in the magnitude of its opening, depending, as indicated, on the operation of the level regulator (or water inspection).

После кланана / трубопровод разветвл етс : часть воды сначала проходит в пароохладитель 3 и затем в экономайзер 4, а часть - неносредственно направл етс  в экономайзер.After the clan / pipeline, a branch splits: part of the water first flows into the desuperheater 3 and then into the economizer 4, and partly is directed directly to the economizer.

Расход воды, проход щей через пароохладитель, зависит только от величины открыти  кланана 5 автоматического (или управл елюго The flow of water passing through the desuperheater depends only on the size of the automatic opening of the clanan 5 (or control unit).
