Abstract

Изобретение относитс  к теплоэнергетике и м.б. использовано дл  автоматизации управлени  газоплотными паровыми котлами. Цель изобретени  - повышение надежности работы котла при пуске. К сумматору (С) 7 подключены задатчик 5 и датчик 6 т-ры пара, а к С 10 - задатчик 8 и датчик 9 деформации изгиба змеевика. Выход С 10 подключен к логическому блоку 11, выход к-рого св зан с переключателем 12, к-рый через регул тор 13 соединен с исполнительным органом 14. К переключателю 12 подсоединены также датчик 9 и С 7. В зависимости от деформации змеевика, к регул тору 13 подключаетс  выход С 7 или выход датчика 9, при этом регулируетс  расход воды на впрыск в пароохладитель. 2 ил.The invention relates to a power system and m. Used to automate the control of gas-tight steam boilers. The purpose of the invention is to increase the reliability of the boiler at start-up. The adder 5 and the sensor 6 are connected to the adder (C) 7 of the pair, and to C 10 - the adjuster 8 and the sensor 9 of the deformation of the coil bend are connected. Output C 10 is connected to logic unit 11, the output of which is connected to switch 12, which through regulator 13 is connected to actuator 14. Sensor 9 and C 7 are also connected to switch 12. Depending on the deformation of the coil, The controller 13 is connected to the output C 7 or the output of the sensor 9, and the water consumption for injection into the desuperheater is regulated. 2 Il.
