Abstract
СПОСОБ ПРОТИВОТОЧНОГО ОХЛАЖДЕНИЯ ПРОТОЧНОЙ ЧАСТИ ЦИЛИНДРА ТУРБИНЫ ПРИ РАБОТЕ В БЕСПАРОВОМ РЕЖИМЕ путем подачи охлаждающего пара в выхлоп цилиндра, отвода его из паровпуска при регулировании расхода пара дл поддержани распределени температуры пара вдоль проточной части на уровне при работе цилиндра на номинальном режиме и дополнительного отвода охлаждающего пара из промежуточной ступени при снижении температуры пара в последующих по ходу пара ступен х, отличающийс тем, что, с целью повьпиени надежности, увеличивают (уменьшают ) расход охлаждающего -пара через ступени до промежуточного отвода при достижении температуры пара в этих ступен х вьше (ниже) номинальной и уменьшают (увеличивают) расход охлджШ дающего пара через последующие ступе (Л ни, регулиру расход дополнительно отводимого пара.METHOD OF CIRCULATING FLOWING PART OF A TURBINE CYLINDER WHEN OPERATING IN A SPIRITUAL MODE by supplying cooling steam to the cylinder exhaust, removing it from the steam inlet when adjusting the steam flow rate to maintain the distribution of the steam temperature along the flow section at the same level as the cylinder operating at nominal mode and additional coolant discharge to maintain the steam temperature distribution along the flow part at the cylinder operating at nominal mode and additional cooling coolant to disperse the steam temperature along the flow part during cooling of the steam at the nominal mode and additional coolant discharge. intermediate stage with a decrease in the temperature of steam in the subsequent along the pair of steps, characterized in that, in order to improve reliability, increase (decrease It goes) the flow of the cooling steam through the steps to the intermediate tap when the steam temperature in these steps is higher (lower) than the nominal one and reduce (increase) the flow of cooling steam through the subsequent steps (L no, adjusting the flow rate of the additional steam).
Description
Изобретение относитс к области энергомашиностроени и может быть использовано как в паротурбостроении при создании новых типов турбин., так и в теплоэнергетике при модернизации турбин на. электростанци х.The invention relates to the field of power plant engineering and can be used both in steam turbine construction in the creation of new types of turbines and in thermal power engineering during modernization of turbines. power plants.
Целью изобретени вл етс повышение надежности цилиндра.The aim of the invention is to improve the reliability of the cylinder.
На фиг.1 изображена принципиальна схема цилиндра дл реализахдш способа с допопнительньм трубопроводом отвода пара из промежуточной ступени; на фиг.2 - то же, при использовании подогревател цилиндра.Figure 1 shows a schematic diagram of a cylinder for the implementation of a method with an additional pipeline for removing steam from an intermediate stage; figure 2 - the same, when using a cylinder preheater.
Цилиндр I с запорным органом 2 в его паровпускной части (паровпускё) 3 содержит сбросной трубопровод 4, сообщающий паровпускную часть 3сCylinder I with shut-off body 2 in its steam inlet part (steam inlet) 3 contains a discharge pipe 4, indicating the steam inlet part 3c
полостью 5 сниженного давлени и снабженный регулирующим клапаном 6. 5 cavity of reduced pressure and equipped with a control valve 6.
Oi Цилиндр 1 турбины имеет трубопроводы СП 7 отборов пара к подогревател м 8 и Oi The cylinder 1 of the turbine has pipelines of the joint venture 7 steam extraction to the heaters 8 and
00 о ел снабжен, по меньшей мере, одним дополнительным отвод щим трубопроводом 9 охлаждающего пара из промежуточной ступени отсека промежуточных ступеней проточной части (не показаны ) . Трубопровод 9 сообщен с полостью 5 сниженного давлени и снабжен регулирующим клапаном 10.The valve is equipped with at least one additional cooling steam discharge pipe 9 from the intermediate stage of the intermediate stage compartment of the flow part (not shown). The pipeline 9 is in communication with the cavity 5 of reduced pressure and is provided with a control valve 10.
В качестве дополнительного отвод щего трубопровода 9 может быть использован один из трубопроводов 4 отбора пара, а в качестве полости 5 сниженного давлени - подогреватель 8. К выхлопу 11 цилиндра 1 подключенAs an additional discharge pipe 9, one of the steam extraction pipes 4 can be used, and a heater 8 as the reduced pressure cavity 5. To the exhaust 11 of the cylinder 1 is connected
