Description
(54) ДВУХВАЛЬНАЯ ПАРОВАЯ ТУРБИНА(54) TWO-WHEELED STEAM TURBINE
Изобретение относитс к теплоэнергетике и может быть использовано на тепловых электростанци х, привлекаемых дл регулировани графиков нагрузки энергосистем в период .сниженных нагрузок.The invention relates to a power system and can be used in thermal power plants, which are used to regulate the load schedules of power systems in the period of reduced loads.
Известна двухвальна парова турбина , оба вала которой содержат цилиндры как низкого, так и высокотемпературные цилиндры других давлений Cl 3Недостатком такой турбины вл етс наличие на обоих валах высокотемпературных цилиндров, что снижает маневренность турбины необходимости длительного прогрева этих цилиндров при пуске.Known twin-shaft steam turbine, both shafts of which contain cylinders of both low and high-temperature cylinders of other pressures Cl 3 The disadvantage of such a turbine is the presence of high-temperature cylinders on both shafts, which reduces the maneuverability of the turbine and the need for prolonged heating of these cylinders during start.
Известна также двухвальна парова турбина, содержаща на одном валу только цилиндры низкого давлени 2.,Also known is a twin-shaft steam turbine containing only low pressure cylinders 2 on one shaft.
Недостатком этой турбины вл ет- . с низка маневренность и экономичность в период-сниженных нагрузок, что определ етс невозможностью отключени одного из валов и необхо-, димостью работы цилиндров низкого давлени (ЦНД) с малыми расходами пара на неоптимальных режимах с HHJThe disadvantage of this turbine is em-. with low maneuverability and efficiency in period-reduced loads, which is determined by the impossibility of disabling one of the shafts and the need for low-pressure cylinders (low pressure cylinders) with low steam consumption in non-optimal conditions with HHJ
КИМ к.оэ.ффициентом полезного действи КПД.CIM, efficiency coefficient of efficiency.
Цель изобретени - повьдценне маневренности и экономичности турбины. .The purpose of the invention is to improve the maneuverability and efficiency of the turbine. .
Указанна цель достигаетс тем, что другой зал турбины снабжен, по меньшей мере, одним цилиндром низкого давлени .This goal is achieved in that the other turbine room is provided with at least one low pressure cylinder.
Ма фиг. 1 изображена схема четы10 рехцилиндровой турбины; на фиг. 2 шестицилиндровой турбины.Ma FIG. 1 shows a diagram of a four-cylinder turbine; in fig. 2 six-cylinder turbines.
Двухвальна парова турбина (четырехцилиндрова ) содержит на одном только ЦНД 2. Другой вал 3 The twin-shaft steam turbine (four-cylinder) contains the LPC 2 alone. Another shaft 3
15 турбины снабжен, по меньшей мере, одним ЦНД 4. На валу 3 установлены также цилиндры 5 и б высокого и среднего давлений (ЦВД и ЦСД). ЦВД 5 подключен подвод щим паропроводом 7 15 turbines are equipped with at least one LPC 4. On the shaft 3 there are also installed cylinders 5 and b of high and medium pressure (HPC and TsSD). CVP 5 is connected with steam supply line 7
20 к котлу (не показан), а трубопроводом 8 - к ЦСД б, который сообщен с ЦНД 2 и 4 соединительным паропроводом 9. На соединительном паропроводе 9 перед ЦНД 2 вала 1 установлены 25 запорные органы 1C. На валах 1 и 3 установлены генераторы 11.20 to the boiler (not shown), and pipe 8 to the central distribution block b, which is connected to the low-pressure cylinder 2 and 4 by the connecting steam line 9. On the connecting steam line 9, 25 shut-off parts 1C are installed before the low-pressure cylinder 2 of shaft 1. On shafts 1 and 3 are installed generators 11.
Двухвальна парова ту{5бина работает следующим образом.Two-shaft steam to {5bin works as follows.
Пар от котла по подвод щему паро30 проводу 7 поступает в ЦВД 5, .откуда Steam from the boiler through the supplying steam 30 wire 7 enters the HPC 5, from where
