Description
(5) СИСТЕМА АВТОМАТИЧЕСКОГО РЕГУЛИРОВАНИЯ РАЗРЕЖЕНИЯ В ТОПКЕ ПАРОГЕНЕРАТОРА(5) AUTOMATIC REGULATION SYSTEM FOR DILUTING IN THE TOP OF THE STEAM GENERATOR
II
Изобретение относитс к регулированию процесса горени в топках паро-, генераторов, оборудованных вращающимис регенеративными воздухоподогревател ми .The invention relates to the regulation of the combustion process in steam furnaces, generators, equipped with rotating regenerative air preheaters.
Известна система автоматического регулировани разрежени в топке парогенератора с регенеративным вращающимс воздухоподогревателем, содержаща направл ющие аппараты дымососа, подключенные к регул тору, св занному с задатчиком, датчиком разрежени и дифференциатором, к которому подключены два источника корректирующих сигналов. В качестве источников корректирующих сигналов в известной системе использованы датчики положени направл ющих аппаратов дутьевых вентил торов 11.A system is known for automatically regulating the vacuum in the furnace of a steam generator with a regenerative rotary air heater, which contains exhaust fan guides connected to a regulator connected to a regulator, a vacuum sensor and a differentiator to which two sources of correction signals are connected. As sources of correction signals in a known system, sensors of the position of the guiding devices of the blower fans 11 are used.
Недостатком известной системы вл етс снижение качества, регулирова-i ни из-за пульсаций давлени воздуха.A disadvantage of the known system is a reduction in quality, regulated by either air pressure pulsations.
Целью изобретени вл етс повышение качества регулировани путем уменьшени вли ни пульсаций.The aim of the invention is to improve the quality of regulation by reducing the influence of pulsations.
Поставленна цель достигаетс тем, что оба источника корректирующих сигналов выполнены в виде датчиков перепада давлений соответственно воздуха и газа на воздухоподогревателе и включены встречно.This goal is achieved by the fact that both sources of correction signals are made in the form of pressure difference sensors, respectively, of air and gas on the air preheater and are switched in opposite.
На чертеже представлена схема системы .The drawing shows a diagram of the system.
Система содержит парогенератор 1, вращающийс воздухоподогреватель (РВВ) 2,дымосос J и дутьевой вентил тор 4 и направл ющие аппараты 5, 6, The system includes a steam generator 1, a rotating air preheater (RVB) 2, a smoke exhauster J and a blower fan 4 and guide vanes 5, 6,
ts дымоЬоса и вентил тора соответственно, мельничную систему 7 с пр мым вдуванием пыли, датчики 8-10 - разрежени в верхней части топки и перепада на газовой и воздушной стороне РВВ ts of smoke and fan, respectively, mill system 7 with direct injection of dust, sensors 8-10 - dilution in the upper part of the furnace and differential on the gas and air side of the RVV
