Description

Изобретение относитс  к области теплоэнергетики и может быть применено дл  парогазовых устаиовок тепловых электростанций, осущ ,ествленных но схеме со сбросом газов от газовой турбины в нарогенератор и с донолнительиым сжиганием топлива в тоике последнего .The invention relates to the field of heat and power engineering and can be applied for steam-gas installation of thermal power plants, implemented in a scheme with discharge of gas from a gas turbine into a narogenerator and with full fuel combustion in the latter.

Известны способы регулировани  процесса теилообмена в поверхност х нагрева парогенератора нутем подачи более холодных газов в верхнюю и нижнюю части тоночной камеры.Methods are known for regulating the heat exchange process in the heating surfaces of the steam generator by supplying cooler gases to the upper and lower parts of the thin chamber.

По известным способам регулировани  процессов горени  и теплообмена в парогеиераторах сжигаютс  только расчетные виды топлива , сравнительно близкие по физическим свойствам . Однако эффективное сжигание топлива с различными физическими свойствами в одиом иарогеиераторе требует широкого диапазона темнератур тоиочного процесса. Кроме того, нри сжигании различных видов топлива в парогенераторе тепловоснри тие отдельных его элементов различно.According to the known methods for regulating the processes of combustion and heat exchange in steam gages, only calculated fuels that are relatively similar in physical properties are burned. However, efficient combustion of fuels with different physical properties in a single arc gaming system requires a wide range of thermal processes. In addition, when different types of fuel are burned in a steam generator, the thermal absorption of its individual elements is different.

По предлагаемому способу с целью обеспечени  онтимального сжигани  различных но физнческим свойствам видов тонлива и нолучени  требуемых расчетных параметров пара в нарогенераторе без необходимости заложени  больших доиолнительных поверхностей нагрева дл  возможности их регулировани  температуру подогрева воздуха регулируют вAccording to the proposed method, in order to ensure optimal burning of various types of tonnage types and obtaining the required design parameters of steam in the narogenerator without the need to install large additional heating surfaces in order to regulate them, the temperature of air heating is adjusted to

зависимости от неооходнмого содержани  кислорода в отработавших газах турбины, подаваемых в гонку парогенератора, и этим вли ют на процесс горени  и теплообмена.dependencies on the low oxygen content in the exhaust gases of the turbine supplied to the steam generator race, and this affects the process of combustion and heat exchange.

По предлагаемому способу также поддерживают посто нное процентное содержание кнслорода в отработавшнх газах турбнны при пзменепи х нагрузки как турбины, так и парогенератора или возможных нарушени х рел имов при эксплуатации парогазовой установки, что необходимо дл  снижени  потерь от недожога . Это дос1игаетс  тем, что температуру подогрева воз:,уха поддержпвают посто иной путем регулированн  расхода тенлоносител , подаваемого в воздухоподогреватель.The proposed method also maintains a constant percentage of the oxygen content in the exhaust gases of the turbine at the load of both the turbine and the steam generator or possible disturbances of the connections during the operation of the combined-cycle plant, which is necessary to reduce losses from incineration. This is achieved by the fact that the temperature of the heater is maintained: the ear is constantly maintained by regulating the flow rate of the tenon carrier supplied to the air preheater.

Па чертеже показана примерна  схема парогазовой установкп дл  осуществлепи  предложеииого способа.Pa the drawing shows an exemplary diagram of the combined-cycle plant for carrying out the proposed method.

Схема содержит парогеператор / с пароперегревателем 2, воздухоподогревателем 5 и вод ным экономайзером 4, воздушпый компрессор 5, камеру сгорани  6, газовую турбииу 7 и электрогенератор 8.The scheme contains a steam heater / with a superheater 2, an air heater 5 and a water economizer 4, an air compressor 5, a combustion chamber 6, a gas turbine 7 and an electric generator 8.

Установка работает следующим образом.The installation works as follows.

Воздух из компрессора 5 направл етс  в воздухоподогреватель 3 п затем в камеру сгораии  6, к которой примыкает устройство 9 дл  подачи топлива. Продукты сгорани  из камеры 6 нанравл ютс  в газовую турбину 7, и отработавшие в турбине газы подаютс  вThe air from the compressor 5 is directed to the air preheater 3 and then to the combustion chamber 6, to which the fuel supply device 9 adjoins. The combustion products from chamber 6 are fed to the gas turbine 7, and the gases that are spent in the turbine are fed to
