Abstract

The heat from gas turbine exhaust is used to generate steam in a boiler and the steam generated is used to power a steam turbine. When, for example, two gas turbines 1 and one steam turbine 3 are provided in a station, and when it is desired to operate at full load in driving generators or compressors 2, both gas turbines 1 are operated and the heat from their exhaust generates enough steam to drive the steam turbine. However, when it is desired to operate at partial load only one gas turbine 1 is operated and additional steam is generated in associated boiler 4 by supplemental fuelling equipment 5. In this way, a combined cycle station can be operated at near maximum efficiency when running below peak power. <IMAGE>

РСотлы-утилизаторы 5 и 6 паропроводами 8 и 9 подключены к паровой турбине 10, привод щей в действие мадшнный агрегат 11 . Соотношение количества газовых турбин 1 и 2 и паровых трубив 10 может составл ть 2:1, 1:1 или комбинацию этих величин, и/или кратное им отношение.The installation of a compressor or electric station contains gas turbines 1 and 2, which are driven by machine units (compressors or generators.) 3 and 4 and communicated through the exhaust gases to the waste heat boilers 5 and 6 and their additional furnaces 7. The waste heat exchangers 5 and 6 with steam lines 8 and 9 are connected to a steam turbine 10, which drives the madness unit 11. The ratio of the number of gas turbines 1 and 2 to steam pipes 10 may be 2: 1, 1: 1, or a combination of these values, and / or a multiple ratio.

При работе с полнор или близкой к ней нагрузкой газовые турбины 1 и 2 привод т в действие машинные агрегаты 3 и 4, а уход щие газы из газовьк турбин 1 и 2 поступают в котлы-утилиза- торы 5 и 6. За счет тепла уход щргх (дымовых) газов котлы-утилизаторы 5 и 6 вырабатывают (генерируют) пар, котрый подаетс  в паровую турбину 10 дл  приведени  в действие машинного агре- гата 11, т.е. дл  обеспечени  его полной (номинальной) мощности. В котлах- утилизаторах 5 и 6 генерируетс  пар с давлением 2,5-5,0 МПа и температурой 350-450°С.. When working with a full load or close to it, gas turbines 1 and 2 drive the power units 3 and 4, and the exhaust gases from the gas turbines 1 and 2 enter the waste-heat boilers 5 and 6. Due to heat loss (flue) gases, waste heat boilers 5 and 6 generate (generate) steam, which is supplied to the steam turbine 10 to drive the engine unit 11, i.e. to ensure its full (nominal) power. In waste heat boilers 5 and 6, steam is generated with a pressure of 2.5-5.0 MPa and a temperature of 350-450 ° C.

При снижении нагрузки установки отключают по меньшей мере одну, например , газовую турбину 1. В работе- остаютс  газова  турб1ша 2, котел-утилизатор 6 и парова  турбина 10.

In operation, the gas turbine 2, the waste heat boiler 6 and the steam turbine 10 remain. In addition, the final furnace 7 serves fuel and

Дл  повьппени  готовности к работе установки, состо щей, например, из одной газовой турбины 2 и одной паровой турбины 10, может быть использован котел-утилизатор 6 с топкой (не показана), обеспечивающей расход пара требуемых параметров дл  полпой мощности паровой турбины 10 независимо от газовой турбины 2. Обеспечение полной мощности паровой- турбины 1 О повышает экономичнос установки при работе с неполной на- гоузкой.from the gas turbine 2, flue gases in whose oxygen they burn fuel When burning fuel, they increase the vapor pressure to 5.0–10.0 MPa and temperature to 450–520 ° C. The steam turbine 10 is supplied with the amount of steam of the required parameters to maintain its full capacity, i.e. the power that was before the shutdown of the gas turbine 1. To make the plant ready for operation, for example, consisting of one gas turbine 2 and one steam turbine 10, a waste heat boiler 6 with a firebox (not shown) can be used to ensure steam consumption of the required parameters for full-power steam turbine 10 regardless gas turbine 2. Providing the full power of a steam turbine 1 O increases the economics of the installation when operating with an incomplete bore.
