Description
регул тор питани 2 (например регу- л тЬр соотношени вода-топливо), увеличивает подачуВОДЫ в котел. Это приводит к понижению температур пара в тракте котла, а значит и температуры пара перед пароохладителем. Регул тор впрыска, работающий по любой схеме, уменьшением расхода воды на впрыск восстанавливает , заданный перепад температур на пароохладителе , сохранив тем. самым заданный , (расчетный) процент расхода воды на впрыск. При уменьшении этой разности схема работает аналогично в сторону уменьшени подачи питательной воды.power regulator 2 (e.g. water-fuel ratio control), increases the supply of WATER to the boiler. This leads to a decrease in the temperature of the steam in the boiler path, and hence the temperature of the steam in front of the desuperheater. The injection controller operating in any scheme, by reducing the consumption of water for injection, restores the predetermined temperature difference on the desuperheater, saving it. the most specified (calculated) percentage of water consumption for injection. When this difference is reduced, the circuit operates similarly in the direction of reducing the feedwater supply.
При отключени х регул тора впрыска ; (отказах) или отклонении температуры пара перед пароохладителем за допустимые . пределы устройство 9 (возможна релей- |,на реализаци ) автоматически отключаетWhen the injection controller is turned off; (failure) or temperature deviation of the steam before the desuperheater for acceptable. the limits of device 9 (possible relay- |, on implementation) automatically turns off
блок 4 от корректирующего регул тора 1, 4t6 обеспечивает регулирование температуры пара перед пароохладителем на « уровне, установленном задатчиком 7.The block 4 from the correction regulator 1, 4t6 ensures the regulation of the temperature of the steam in front of the desuperheater at the level set by the setpoint 7.
Предмет изобретени Subject invention
Схема автоматического регулировани питани пр моточного котла, оснащенного пароохладител ми с регул торами темп&ратуры пара, содержаща регул тор пита НИН, отличающа с тем, что, с целью повышени надежности в работе : поверхностей наг рева котла, расположен-: ных до первого пароохладител , на вход регул тора питани подключены датчик температуры пара до и после первого по ходу пара пароохладител .The scheme of automatic control of the power supply of the boiler of the steam boiler equipped with steam coolers with regulators of steam temp & a steam regulator NIN, characterized in that, in order to improve reliability in operation: heating surfaces of the boiler, located before the first steam cooler , a steam temperature sensor is connected to the input of the power regulator before and after the first along the steam desuperheater.
