(54) СПОСОБ АВТОМАТИЧЕСКОГО РЕГУЛИРОВАНИЯ ПРОЦЕССА ГОРЕНИЯ В ПАРОГЕНЕРАТОРЕ(54) METHOD FOR AUTOMATIC REGULATION OF THE COMBUSTION PROCESS IN THE STEAM GENERATOR
1one
Изобретение относитс к теплоэнергетике , в частности к автоматическому управлению процессом горени в парогенераторе.The invention relates to a power system, in particular, to automatic control of the combustion process in a steam generator.
Известны способы автоматического регулировани процессом горени в парогенераторе путем воздействи на подачу топлива и воздуха по соотношению атих расходов с коррекцией по содержанию кислорода в дымовых . газах t JMethods are known for automatically regulating the combustion process in a steam generator by influencing the flow of fuel and air according to the ratio of flow rates with a correction for the oxygen content in the flue gas. gases t J
Однако способ не позвол ет достигнуть требуемого качества управлени .However, the method does not allow to achieve the desired quality control.
Цель изобретени - повышение качества управлени .The purpose of the invention is to improve the quality of control.
Поставленна цель.достигаетс тем, что дополнительно измер ют разрежекре в топке и расход дымовых газов с последукщим воздействием на величину удалени последних по суммарному сигналу соотношени расходов воздуха и топлива, разрежени в топке и расхода дымовых газов.This goal is achieved by additionally measuring the cut-off in the furnace and the flow rate of flue gases with a subsequent effect on the amount of removal of the latter by the total signal of the ratio of the flow rates of air and fuel, the vacuum pressure in the firebox and the flow rate of flue gases.
при этом по полученнсму суммарноУ4у сигналу дополнительно корректируют расходы воздуха и топлива. at the same time, according to the received total signal, the air and fuel consumption is additionally corrected.
На чертеже представлена блок-ахема устройства, реализующего данный способ..The drawing shows the block-Achema device that implements this method ..
Устройство содержит датчик 1 кислорода , корректирующий регул тор 2 кислорода, датчик 3 расхода топлива , блок 4 сравнени топливо-воздух, The device contains an oxygen sensor 1, an oxygen correction controller 2, a fuel consumption sensor 3, a fuel-air comparison unit 4,
to датчик 5 расхода воздуха, регул тор 6 топлива, регул тор .7 воздуха, задатчик 8 по нагрузке, регул тор 9 дымовых газов, датчик 10 расхода дымовых газов, блок И сравнени to air flow sensor 5, fuel regulator 6, air regulator .7, unit 8 for load, flue gas controller 9, flue gas flow sensor 10, unit. And compare
15 топливо-воздух и дымовые газы, корректирующий регул тор 12 разрежени , датчик 13 разрежени .15 fuel-air and flue gases; an adjusting regulator 12; a vacuum pressure regulator;
Способ реализуетс следующим образом .The method is implemented as follows.
2020
Датчиками 1, 3 и 5 измер ют соответственно концентрацию кислорода, расход топлива и расход воздуха в парогенераторе при помошл регул тоSensors 1, 3 and 5 measure the oxygen concentration, fuel consumption and air consumption in the steam generator, respectively.
