Description
Изобретение относится к области парогенераторостроения и может быть использовано при эксплуатации парогенераторов тепловых электростанций в условиях резкопеременных графиков нагрузки с частичными остановами оборудования.The invention relates to the field of steam generation and can be used in the operation of steam generators of thermal power plants in the conditions of rapidly changing load schedules with partial shutdowns of equipment.
Наиболее близок из известных технических решений к описываемому изобретению способ работы находящегося в резерве парогенератора, содержащего снабженный отводящим паропроводом пароперегреватель, путем подачи в последний пара в течение всего периода нахождения парогенератора в резерве [1].The closest known technical solution to the described invention is the method of operation of a steam generator in reserve containing a steam superheater equipped with an outlet pipe by supplying the last steam during the entire period of the steam generator being in reserve [1].
Недостатком такого способа является низкая экономичность и надежность в период пуска парогенератора.The disadvantage of this method is the low efficiency and reliability during the start-up of the steam generator.
Цель изобретения — повышение экономичности и надежности в период пуска парогенератора.The purpose of the invention is to increase efficiency and reliability during the start-up of the steam generator.
Указанная цель достигается тем, что пар в пароперегреватель подают через отводящий паропровод и поддерживают его температуру близкой к номинальной.This goal is achieved by the fact that steam is supplied to the superheater through the outlet steam line and its temperature is kept close to the nominal value.
На чертеже изображена схема реализации предлагаемого способа.The drawing shows a diagram of the implementation of the proposed method.
После останова парогенератора в резерв из магистрального паропровода 1 по отводящему паропроводу 2, снабженному задвижками 3, подают пар в пароперегреватель 4 и сбрасывают его через дренажный патрубок 5. При этом путем подпиток поддерживают средний уровень воды в барабане 6 в течение всего периода нахождения парогенератора в резерве.After stopping the steam generator from the main steam line 1 through the outlet steam line 2 equipped with valves 3, steam is supplied to the superheater 4 and dumped through the drain pipe 5. In this case, the average water level in the drum 6 is maintained by recharge during the entire period of the steam generator being in the reserve .
Температуру пара, подаваемого в пароперегреватель 4, поддерживают близкой к номинальной в течение всего периода нахождения парогенератора в резерве.The temperature of the steam supplied to the superheater 4 is kept close to the nominal temperature during the entire period the steam generator is in reserve.
Использование предлагаемого способа работы находящегося в резерве парогенератора позволяет повысить экономичность и надежность последующего пуска парогенератора.Using the proposed method of operation of a steam generator in reserve allows to increase the efficiency and reliability of the subsequent start-up of the steam generator.
