Description
Изобретение относитс к теплоэнергетике и предназначаетс дл регулировани процесса горени в топках с кип щим слоем.The invention relates to a power system and is intended to regulate the combustion process in fluidized bed furnaces.
Целью изобретени вл етс повышение точности регулировани .The aim of the invention is to improve the accuracy of regulation.
На чертеже представлена схема устройства , реализующего данный способ.The drawing shows a diagram of the device that implements this method.
Топка содержит камеру 1 сгорани кип щего сло 2, барабан 3, газораспределительную решетку 4. Топливо 5 подаетс в топку в верхнюю часть сло 2, а воздух дл псевдоожижени по воздуховоду 6 - в нижнюю часть топки под газораспределительную рещетку 4.The furnace contains a combustion chamber 1 of the fluidized bed 2, a drum 3, a gas distribution grid 4. Fuel 5 is supplied to the furnace in the upper part of layer 2, and air for fluidization through the duct 6 is supplied to the lower part of the furnace for the gas distribution grid 4.
Волноводами 7 и 8 боковые поверхности топки соединены с пьезокерамическим преобразователем 9, соединенным с блоком 10 выпр мителей. Один выход последнего соединен с вторичным прибором 11. Датчик 12 даилеимч в барабане 3 соединен с входом ре у;1 тора 13 тепловой нагрузки, выход которого подключен к регулирующему органу 11, расположенному на воздуховоде 6, а датчик 15 расхода воздуха соединен с другим входом регул тора 13. Выход регул тора 16 соотношени первичный воздух - топливо соединен с регулирующим органом 17 расхода топлива, а входы - с датчиBy waveguides 7 and 8, the lateral surfaces of the furnace are connected to a piezoceramic transducer 9 connected to a rectifier unit 10. One outlet of the latter is connected to the secondary device 11. The sensor 12 in the drum 3 is connected to the inlet of the heater; 1 torus 13 of the heat load, the output of which is connected to the regulator 11 located on the duct 6, and the sensor 15 of the air flow is connected to another regulator inlet torus 13. The output of the regulator 16 is the ratio of primary air - the fuel is connected to the regulator 17 of the fuel consumption, and the inputs are from the sensor

ком 18 расхода топлива, датчиком 15 и входо.м блока 10.com 18 fuel consumption, the sensor 15 and vodome.m block 10.
Способ осуп1ествл етс следующим образом .The method is described as follows.
При изменении тепловой нагрузки происходит изменение давлени в барабане, сигнал от датчика 12 давлени в барабане 3 поступает на вход регул тора 13 тепловой нагрузки, где сравниваетс с сигналом датчика 15 расхода воздуха. Регул тор 13 измен ет положение регулирующего органа 14 расхода первичного воздуха. При изменении расхода первичного воздуха по сигналу от датчика 15 регул тор 16 формирует регулирующее воздействие на регулирующий орган 17 расхода топлива. Коррекци поддерживаемого соотношени первичный воздух-топливо осуществл етс с по.мощью пьезокерамического акустического преобразовател 9, на вход которого по волноводам 7 и 8 поступает звуковой сигнал. Уровень звукового сигнала зависит от скорости псев- доожижающего потока. После акустического преобразовател 9 сигнал поступает в блок 10 выпр мителей. Выпр мленный сигнал подаетс на вход регул тора 16. Вторичный прибор 11 показывает уровень звуковых колебаний в слое.When the heat load changes, the pressure in the drum changes, the signal from the pressure sensor 12 in the drum 3 arrives at the input of the heat load regulator 13, where it is compared with the signal from the air flow sensor 15. The regulator 13 changes the position of the regulator 14 of the primary air flow rate. When changing the flow rate of the primary air signal from the sensor 15, the regulator 16 forms a regulating effect on the regulator 17 of the fuel consumption. The maintenance of the correlation of the primary air-fuel ratio is carried out with the help of a piezoceramic acoustic transducer 9, at the input of which a sound signal is sent to the waveguides 7 and 8. The sound level depends on the velocity of the pseudo-fluidizing flow. After the acoustic transducer 9, the signal enters the rectifier unit 10. The rectified signal is fed to the input of the controller 16. The secondary device 11 indicates the level of sound vibrations in the layer.
