Description
Изобретение относитс к автоматизации тепловых процессов и может быть использовано на станци х с общим паровым коллектором.This invention relates to the automation of thermal processes and can be used at stations with a common steam collector.
Известен способ регулировани производительности котлов, работающих на общий паровой коллектор, путем подачи задающего воздействи от главного регул тора на индивидуальные регул торы тепловых нагрузок,, при этом сохран етс заданное соотнощение между паропроизводительност ми отдельных котлов 1.There is a method of controlling the performance of boilers operating on a common steam collector by applying a driver action from the main controller to individual thermal load controllers, while maintaining a predetermined ratio between the steam generators of the individual boilers 1.
Однако этот способ не учитывает количество работающих горелок, вентил торов , дымососов, технологические ограничени , необходимость изменени соотношени нагрузок при изменении количества работающих котлов, что ведет к сужению диапазона регулировани станции и снижению эксплуатационного КПД котла.However, this method does not take into account the number of operating burners, fans, smoke exhausters, technological limitations, the need to change the load ratio when the number of operating boilers changes, which leads to a narrowing of the station control range and a decrease in the operating efficiency of the boiler.
Наиболее близким к предлагаемому по технической сущности вл етс способ регулировани котлов с общим паровым коллектором путем определени верхних и нижних пределов паропроизводительности , разрежени , расходов -топлива, воздуха и воды каждого котла, использовани этих пределов в качестве ограничивающих параметров , измерени давлени пара в коллекторе и регулировани подачи топлива в один из котлОв до достижени каким-либо ограничивающим параметром одного из пределов с последуквдим переключением регулирующего воздействи на другой котел 23The closest to the proposed technical essence is the method of regulating boilers with a common steam manifold by determining the upper and lower limits of steam production, vacuum, flow rates of fuel, air and water of each boiler, using these limits as limiting parameters, measuring steam pressure in the collector and regulating the supply of fuel to one of the boilers until one of the limiting parameters reaches one of the limits, with subsequent switching of the regulating effect on the other corner boiler 23
Недостатком способа вл етс низка экономичность процесса регулировани в св зи с тем, что не учитываетс экстремальный характер зависимости коэффициента полезного действи котлов от паропроизводительности .The disadvantage of this method is the low efficiency of the regulation process due to the fact that the extreme nature of the dependence of the efficiency of the boilers on the steam production is not taken into account.
Цель изобретени - повышение наг чества регулировани .The purpose of the invention is to increase the regulation power.
