The article presents a detection system with spider web coil-based wireless charging. Commonly available metal detectors are sold as handheld systems, which enable only progressive, lengthy, time-consuming search. Importantly, a part of the investigated area can thus be easily missed, and the probability that a metal object will not be found increases substantially. This problem, ...

The article deals with the district heating systems transition to intelligent systems by developing a united information system and obtaining a high level of controllability of the en-tire system. During the implementation of automated control systems of district heating, a number of information tasks of the lower level are being introduced, including the data collection for ...

Currently, the world is characterized by quite a large number of military conflicts, manmade disasters and natural disasters. Every year, about 50 thousand people die from various natural disasters in the world. The report of the UNISDR notes that natural disasters that occurred in the world between 1998 and 2017 led to the death of 1.3 million people (more than half of them – ...

Electromagnetic transients are considered in the implementation of three-phase automatic reclose on the transmission line of extra high voltage 750 kV. The influence of automatic shunting of phases and pre-insertion active resistance for limiting the characteristics of the aperiodic component of the current, which obstructs the transition of full current through zero, is evaluated. ...

At present, an actual trend in the development of fuel and energy complexes in a number of countries is the diversification of generation via the involvement of local types of solid fuel. In this case, thermochemical processing of fuel is often carried out in a fluidized state. A significant proportion of dispersed fuels cannot be transferred to a state of stable fluidization. ...

Разработана методика расчета экономической эффективности, которая может быть универсальной и использоваться для технико-экономического обоснования установки системы шариковой очистки конденсатора на паровых турбинах электростанций. Данная методика, кроме эффекта от снижения давления отработавшего пара в конденсаторе за счет внедрения системы шариковой очистки, учитывает также ...

The problems of energy, environment protection and ecology play a major role in the development of economy strategy in any country. Most of the traditional power stations operating on organic fuels have a negative impact on the environment. Furthermore, there is a depletion of natural resources due to human activities. One of the ways to solve the problem of environmentally ...

As in the whole world, there are regions in Russia that experience heat supply difficulties, mainly due to the high cost of fossil fuel as well as to growth of energy resources cost and polluting emissions. In this regard, search for solutions which would provide energy saving with an increase of energy, commercial and ecological efficiency of modern heat supply systems is becoming ...

The combustion of hydrocarbon fuels in the chambers of heat generating plants is one of the main sources of pollutant emissions. Environmental standards and rules that limit emissions are becoming more stringent and their implementation requires the introduction of advanced technologies and equipment. The main device in combustion systems are blow burners, the design of which ...

The paper presents a fragment of ongoing investigations directed on creation of optimal information environment that ensures an access to the R&D publications from the known scientific journals and other scientific serials which are necessary for qualitative execution of scientific and technological activities on priority areas in highway engineering. A citation analysis has been ...
