Description
(54) УСТРОЙСТВО ДЛЯ РЕГУЛИРОВАНИЯ НАГРЕВА ВОЗДУХОНАГРЕВАТЕЛЕЙ ДОМЕННЫХ ПЕЧЕЙ(54) DEVICE FOR REGULATING HEATING OF AIR HEATERS OF DOMAIN FURNACES
I I
Изобретение относитс к автоматизации технологических процессов черной металлургии и может.быть использовано дл регулировани нагрева воздухонагревателей доменных печей.The invention relates to the automation of technological processes in the ferrous metallurgy and may be used to control the heating of blast furnace stoves.
Известно устройство дл регулировани температуры купола воздухонагревател доменной печи, содержаща сравнивающие устройства, регул тор соотношени газ-воздух, корректирующий регул;гтор и исполнительный механизм flj.A device for controlling the temperature of a dome of an air heater of a blast furnace, comprising comparing devices, a gas-air ratio controller, a corrective regulator, and a flj actuator, is known.
Недостатком известного устройства вл етс то, что оно не может оптимизировать коэффициент COOTJJOшени газ-воздух t учетом изменени параметров газа и воздуха.A disadvantage of the known device is that it cannot optimize the gas-air ratio COOTJJO t taking into account changes in the parameters of gas and air.
Наиболее близким по технической сущности к предлагаемому вл етс . устройство, содержащее датчики расхода газа, расхода воздуха, температуры купола, задатчик температуры купола и регул тор соотношени газ-воздух Г23.The closest in technical essence to the proposed is. a device containing sensors for gas flow, air flow, dome temperature, dome temperature setter and G23 air-gas ratio controller.
Это устройство обладает теми же недостатками, что и предыдущее, к тому же наличие в составе устройства кроме регул тора соотношени экстремального регул тора усложн ет устройство и затрудн ет его настройку .This device has the same drawbacks as the previous one; besides, the presence of an extremal controller in the composition of the device, apart from the ratio controller, complicates the device and makes it difficult to adjust.
Цель изобретени - сокращение времени нагрева и улучшение качества регулировани .The purpose of the invention is to reduce the heating time and improve the quality of regulation.
10ten
Указанна цель достигаетс тем, что устройство, включающее датчики расхода газа, расхода воздуха, температуры купола, задатчик температуры купола и регул тор соотношени This goal is achieved by the fact that the device includes sensors for gas flow, air flow, dome temperature, dome temperature setter and ratio controller
