description Publicationkeyboard_double_arrow_right Article 2021Publisher:ЗАО "Научно-техническая фирма "Энергопрогресс" One of the most effective and reliable ways to increase the efficiency of CHP is the organization of heating raw water in the condensers of cogeneration turbines with the simultaneous supply of circulating water through the main bundles. The temperature of raw water supplied to the chemical water treatment at most CHP plants should not exceed 30-40 °C. Fulfillment of this condition is not always possible, and it becomes necessary to analyze and adjust the operating modes of turbines, which provide the most effective heating of water in the built-in bundles. Such an analysis can be carried out quite simply on the basis of operational data and a mathematical model of the condenser developed at the Department of Heat Engineering and Hydraulics of VyatSU. In this paper, an analysis algorithm is considered based on the actual data obtained during the tests of the condenser of the PT-80-130 turbine unit in the mode of its operation according to the electrical schedule, conclusions are drawn from the analysis results. Один из наиболее надёжных способов повышения эффективности ТЭЦ -- организация подогрева сырой (подпиточной) воды в конденсаторах теплофикационных турбоустановок при одновременной подаче циркуляционной воды через основные пучки. Температура сырой воды, подаваемой в цех химводоочистки, на большинстве ТЭЦ не должна превышать 30 - 40\\оС. Выполнение данного условия не всегда возможно, и возникает необходимость анализа и корректировки режимов эксплуатации турбоустановок, обеспечивающих наиболее эффективный подогрев воды во встроенных пучках. Проведение такого анализа достаточно просто можно выполнить на основе эксплуатационных данных и математической модели конденсатора, разработанной на кафедре теплотехники и гидравлики ВятГУ. В данной работе рассмотрен алгоритм проведения анализа на основе фактических данных, полученных при испытаниях конденсатора турбоустановки ПТ-80-130 в режиме её работы по электрическому графику, сделаны выводы по результатам анализа.

Причина может состоять только в том, что вещество внутреннего ядра Земли находится в состоянии квантовой сцепленности, которое возникло при образовании Земли. Оно исчезнет сразу после того, как закончится период Брюнеса, при этом прекратится существование геомагнитного поля. The article explains why despite the increasing density and external pressure the velocities of P-and S-waves do not increase as they approach the center of the inner G-core of the Earth. The reason can only be that the matter of the inner core of the Earth is in a state of quantum entanglement, which arose at the formation of the Earth and will disappear immediately after the end of the Brunhes chron when the geomagnetic field disappears.

Правила проектирования и монтажа”. Нормативные значения удельной расчетной электрической нагрузки, представленные в гл. 7 данного свода правил, требуют пересмотра. Научно-исследовательская работа, проведенная Ассоциацией “Росэлектромонтаж”, показала, что фактические значения нагрузки объектов в 1,5 - 2,5 раза ниже расчетных. Разработаны новые их значения для Республики Татарстан. В результате снизились стоимость и сроки строительства электрических сетей для электроснабжения жилых зданий. Приведены структура и анализ электропотребления в зависимости от региона, рассмотрен экономический эффект от актуализации удельных электрических нагрузок для электросетевой и строительной отраслей.
