When the autumn cold comes, and the temperature on the street drops rapidly, the heating season begins. For trouble-free and uninterrupted operation of any power system, careful and professional preparation of all thermal facilities is required, which must be started in advance. One of the main points of prevention of emergency wear and prevention of equipment malfunctions is modernization, which should guarantee the utmost reliability and high efciency of operation of thermal facilities.
This review is devoted to a comparative analysis of traditional recuperators; rotary, lamellar, with an intermediate heat carrier and their derivatives SDAR units based on heat pumps. The purpose of the analysis is to identify areas of application of combined supply and exhaust ventilation with vapor compression air recuperation, where its operation is more proftable than standard schemes.
The article discusses issues related to the possibility of using renewable energy sources, the integration of renewable energy sources with diesel generation, possible schemes for creating autonomous hybrid energy systems, including renewable energy sources, as well as issues of economic efciency of using renewable energy sources for power supply of isolated and hard-to-reach territories.
The article discusses the technology of disposal of landfll gas in gas piston plants for the generation of electrical energy on the examples of projects implemented by LLC "Prodex Energy" in Russia. The importance of generating plants operating on the basis of landfll gas has been substantiated for improving the environment and reducing the risk of fre in solid waste landflls.
The editorial board of the magazine "Chief Power Engineer" presents an overview of materials and technologies, including: energy-efcient pumping equipment, the use of waste from a coal-fred power plant in the improvement of heat-insulating materials, protective materials based on epoxy resin, the transfer of recirculation of circulating water to winter mode, the introduction of currentcarrying parts of electrical installations (JSC "Grid Company" from Tatarstan), the introduction of energy-efcient technologies in the operation of Aksu Power Plant, improving the energy efciency of cooling systems for data processing centers (DPC).
The article describes modern workwear for power engineers, which protects against the thermal risks of an electric arc and short-term exposure to an open fame. Experts of the Energocontract Group of Companies explain what fabrics are used today to create heat-resistant sets, compare their advantages and disadvantages, and describe the protection mechanisms. Also, the material will talk about how the efectiveness of heat-resistant personal protective equipment (PPE) is checked during tests, and what kind of protective clothing is required for power engineers in the autumnwinter period.
Industrial accidents are most often caused by human factors. Its impact on production can be reduced by increasing the competencies of employees and the quality of their training. To achieve these goals, industrial companies use solutions based on immersive technologies. For example, virtual simulators for training employees to work with equipment. With the help of them, the personnel of industrial enterprises can practice skills in a safe environment, and not at a real facility. The virtual environment allows you to simulate any scenario, including emergency situations. Thus, the introduction of simulators based on immersive technologies helps industrial companies to reduce the negative impact of the human factor. In turn, this allows them to minimize the risks of injuries and accidents, and sometimes death.
The article discusses regulations on responsibility for cleaning snow and ice in the winter and provides examples of accidents that occurred due to falling snow from the roof and as a result of falling on a slippery surface in the territory of the enterprise.
The article is devoted to the history of the frst power plants of Yekaterinburg – Sverdlovsk in the pre-revolutionary and Soviet times, which played a key role in the development of the city.
The article tells about the history of creation and operation of CHPP-8 of PJSC "Mosenergo", which in 2020 celebrates its 90th anniversary. The frst high-pressure combined heat and power plant was an experimental ground for many scientifc and technical developments, which were subsequently actively used at newly commissioned power plants. 90 years later, CHPP-8 is still an integral part of the Moscow energy system.
In the editorial review, we tell about recent online conferences, webinars, and round tables on energy development, new technologies, and promising developments.
