Description
(5) ПАРОТУРБИННАЯ УСТАНОВКА(5) STEAM TURBINE INSTALLATION
1 one
Изобретение относитс к тепло3HepretHKe и может быть использовано на тепловых электрических станци х.This invention relates to heatheptHKe and can be used in thermal power plants.
Известна паротурбинна установка , содержаща паровую турбину, сообщенную трубопроводами отбора пара соответственно с подогревателем низкого давлени и колонкой деаэратора, установленной на баке-аккумул торе l.A steam turbine installation is known, comprising a steam turbine communicated by steam extraction lines with a low pressure preheater and a deaerator column mounted on an accumulator tank l.
Недостатком известной установки вл етс то, что количество пара, o6v разующегос в баке-аккумул торе при снижении нагрузки турбины, может пре-. вышать Необходимое его количество дл нормального протекани процесса деаэрации. При этом скорость пара в деаэрационной колонке резко возрастает , наблюдаетс вибраци колонки, нарушаетс гидродинамика последней снижаетс качество деаэрации.A disadvantage of the known installation is that the amount of steam o6v discharged in the storage tank when the turbine load decreases, can be-. quit Required amount for the normal process of deaeration. At the same time, the steam velocity in the deaeration column increases sharply, the column vibrates, the hydrodynamics of the latter is disturbed, and the quality of deaeration decreases.
Целы изобретени - повышение качества деаэрации, увеличение надежности работы установки в период снижени нагрузки при работе деаэратора в режиме скольз щего давлени .The purpose of the invention is to improve the quality of deaeration, increase the reliability of the plant during the period of reducing the load when the deaerator is operating in the sliding pressure mode.
Указанна цель достигаетс тем, что установка снабжена переточным трубопроводом, соедин ющим верхнюю часть бака-аккумул тора с трубопроводом отбора пара в подогреватель.This goal is achieved by the fact that the installation is equipped with an overflow pipe connecting the upper part of the storage tank with the steam extraction pipe to the preheater.
Кроме того, переточный трубопровод снабжен регулирующим органом.In addition, the overflow pipeline is provided with a regulatory authority.

На чертеже изображена схема предлагаемой паротурбинной установки.The drawing shows a diagram of the proposed steam turbine installation.
Паротурбинна установка содержит паровую турбину 1, сообщенную трубо5 проводами 2 и 3 соответственно с подогревателем 4 низкого давлени и колонкой 5 деаэратора, установленной на баке-аккумул торе 6. Установка снабжена переточным трубопроводом 7i The steam turbine plant contains a steam turbine 1, connected by pipes 5 and wires 2 and 3, respectively, to a low pressure heater 4 and a deaerator column 5 installed on an accumulator tank 6. The unit is equipped with a downstream pipeline 7i
