This inspection is a kind of operational control, which includes detection of defects of insulation coating and gas leaks by instrumental methods, without opening the pipeline. This simultaneously controls two different levels of failure of the gas pipeline’s serviceability, one of which fully preserves its operability, but creates the possibility of a chain of events threatening to cause a failure in the future (insulation defect), while the other level of failure is, in fact, the case when the failure has already occurred (loss of tightness of the gas pipeline), but before the examination was not detected. All underground gas distribution pipelines are subjected to an instrument inspection with a certain regulatory frequency. The identified damages are subject to mandatory elimination, the serviceability and operability of the gas pipeline are being restored. Thus, periodic instrument inspection is a key technical measure that ensures the management of the technical condition of steel underground gas distribution pipelines. It should be mentioned that the work carried out during the inspection and further repair of gas pipelines is the most extensive and labor-consuming of all those performed on the linear part of the gas distribution system. Accordingly, adequate planning in this area is very important from the point of view of both the reliability and safety of the gas distribution network and the economic and economic one. At the same time, it is quite difficult to ensure the required adequacy of operational control planning and maintenance of engineering facilities in practice, since the maintenance process itself combines regulated and unregulated components and has significant inertia of management. The present article is devoted to the issues of reasonable forecasting of the scope of work on the instrument inspection of steel underground gas pipelines, taking into account a specially identified complex organizational and logistical factor reflecting the influence of existing production practices and management approaches in the field of gas distribution. The forecast is based on the currently relevant time series analysis methods.","PeriodicalId":52141,"journal":{"name":"Energetika.

A fundamental model of the energy system of the Republic of Belarus was also built. The principle of minimizing total system costs is chosen as the objective function for modeling, provided that a number of restrictions imposed on the power system are met. For the purpose of energy system balancing, it was proposed to use the potential of hydropower, viz. existing hydroelectric power plants for scenario 1 and technically possible potential for scenario 2. As a result of the modeling, the structure of electricity production was obtained according to two scenarios. Based on the resulting structure, the cost of producing electrical energy was determined. Two approaches were considered: approach 1 that took into account the cost of electricity production at nuclear power plants which can be classified as new, and approach 2 that took into account the cost of electricity production at nuclear power plants, which can be attributed to the existing generation. The production cost of electricity by 2030 is predicted. When approach 1 is used its level is of 63.3 US dollars/(MW·h) under scenario 2 versus 65.3 US dollars/(MW·h) under scenario 1; when approach 2 is used, its level is of 37.5 US dollars/(MW·h) versus 39.4 US dollars/(MW·h), respectively. Also, the economically feasible potential for using solar energy was determined, which by 2025 will amount to 0.91–1.45 billion kW·h/year, and by 2030 – 2.15–3.46 billion kWh/year; the same for wind energy is 1.55–2.39 billion kW·h/year and 3.69–5.67 billion kWh/year, respectively; the same for hydropower is 1.11–1.45 billion kW·h/year throughout the entire period under review until 2030. Based on the study, it became possible to find out that in the Republic of Belarus it is economically feasible and technically possible to replace up to 20.0 % of electrical energy generation by 2030 with energy produced from renewable energy sources.","PeriodicalId":52141,"journal":{"name":"Energetika.

Currently, there is a tendency to diversify the generation of heat and electricity and to improve solid fuel technologies. These trends actualize the search for mathematical tools for describing and predicting the operation of apparatuses with a fluidized bed of dispersed fuel materials. However, since the mechanics of heterogeneous media (and dispersed media in particular) is to a certain extent in its infancy in relation to the mathematical foundations of modeling, it is often difficult to predict the operation of equipment. In particular, the poor quality of mathematical basis does not allow predicting the fields of concentrations and velocities of the phases of the fluidized bed, although this knowledge serves as the fundamental basis for calculating heat and mass transfer and chemical processes. In the present work, a computational and experimental study of the local hydromechanical characteristics of a monodisperse fluidized bed has been carried out. The mathematical apparatus of the theory of Markov chains was used as a basis for modeling. The tasks were solved in a one-dimensional formulation, which implied the division of the bed in height into cells of small but finite sizes. Fluidized bed phase distributions were described by state vectors whose evolution was controlled by transition probability matrices. The elements of these matrices were matched to the physical parameters of the processes. The model was verified by comparing the calculated predictions with the data of a full-scale experiment conducted as part of the study, aimed at measuring the local velocities of the gas phase inside the fluidized bed. The experimental data with a good accuracy for engineering calculations were described by the proposed model, which makes it possible to consider it as a reliable scientific basis for the computer method for calculating installations using the fluidization technique.","PeriodicalId":52141,"journal":{"name":"Energetika.

The regenerative use of low-temperature heat flows within the CHP that is proposed is possible only on the basis of heat pumps use. In this context, the use of electrically-driven heat pumps (EHP) and absorption heat pumps (AHP) is considered. It is shown that, despite the higher heating coefficient of the EHP, the thermodynamic (exergetic) efficiency and economic efficiency of the AHP are higher. Furthermore, the latter also has operational advantages. It is possible to use heat flows with various heat carriers as AHP drive, those are required for the transfer of thermal energy from a cold source to a hot receiver. In this paper, using the example of the “PT-60” steam turbogenerator unit, which is the most common type for CHP plants of the Belarusian power system, the indicators of the primary fuel use efficiency growth at the CHP plant for the AHP with a steam drive are determined. Three scenarios of the use of AHP as part of the thermal scheme of the CHP are considered, viz. with an increase in generation, with the maintenance of generation or with a decrease in the generation of electric energy. The latter is relevant in the current situation with the Unified Energy System of Belarus. In this case, while maintaining the minimum steam flow into the condenser of 12 t/h, the following increase in the plant efficiency has been obtained: electrical efficiency increased by 0.90 %, energy efficiency – by 0.55 %, and exergetic efficiency – by 0.23 %.","PeriodicalId":52141,"journal":{"name":"Energetika.

According to the time of use of generating capacities, preference should be given to options for covering the hot-water load. Based on the average daily load, the power usage time in this case lies in the range of 6000–6500 hours / year. When choosing the capacity of the equipment, it should be borne in mind that the daily load of hot water supply is extremely uneven and also depends on the  day of the week, while the maximum load exceeds the average daily by 2.5 – 3.0 times. When integrating electricity and heat supply systems, it is advisable to consider options for only night-time electricity consumption or night-time consumption plus consumption during the hours of daytime failures of the electricity consumption schedule. If during the new construction the power of the electrical network may vary depending on the selected option, then during the modernization of the heat supply system, the problem is solved if there is a limitation on the available electrical power. Therefore, the definition of these restrictions is a separate issue. In comparison with the direct consumption of electricity for the needs of heat supply, which is a priori energetically and economically inefficient, the use of hybrid systems in heat supply allows us to solve the multifunctional task of increasing the reliability of energy supply and the stability of the functioning of the power system, which is primarily achieved by solving the problem of balancing the capacity of production and energy consumption from the position of aligning  schedules of energy generation and consumption.","PeriodicalId":52141,"journal":{"name":"Energetika.

In order to balance the UES of Belarus during the operation of two power units of a nuclear power plant at night, the application of adjustment regulatory measures that exceed the available capabilities is required. The almost complete use of the adjusting range of the CHP will forcibly cause, on a larger scale, to the shutdown of the blocks during the load failures at night, followed by the start-up from the non-cooled and hot statuses.

The paper proposes an approach to solving the problem of achieving an effective combination of reliability and efficiency of energy systems on the example of gas turbines and CCGT power units. A generalized desirability function has been obtained, which includes a number of parameters for choosing a rational relationship and mutual influence between the reliability and efficiency of electricity production with the participation of thermal power plant equipment in regulating the daily load schedule.

The lack of reliable methods suitable for use in engineering setting complicates decision-making on the technical development of power units and thermal power plants. When evaluating investments in the equipment of power plant units, it is convenient to use continuous functions. Their use makes it possible to carry out the analysis without cost restrictions. The article proposes a method for estimating capital investments in the boiler island of power units of power plants based on a power parametric function. The method includes an assessment of the cost of a boiler unit with fuel preparation systems within the boiler shop, draught and blast. A specific feature of the method is that the cost of the boiler includes the cost of flue gas purification systems from harmful combustion products in the form of ash, sulfur oxides and nitrogen oxides. The method was developed in an engineering setting. The methodological section demonstrates the performance of the method in assessing capital investments in a boiler island in comparison with the same indicator for the EU countries, the USA and China. When discussing the results of the study, it was found that capital investments in a coal-fired boiler with flue gas purification systems is in the range of US$ 25–200 million, depending on the power and initial steam parameters. The share of the cost of environmental flue gas purification systems is 28–50 % of the total cost of the boiler unit. It is demonstrated that the design of coal-fired power units with flue gas purification systems for supercritical parameters with a capacity of less than 300 MW is inefficient due to low competitiveness in terms of specific investments in the boiler.","PeriodicalId":52141,"journal":{"name":"Energetika.

Based on the study and analysis of numerous sources, the ranges of changes in the Lykov, Posnov, and phase transformation criteria for the processes of heat treatment of ceramics, asbestos, felt, and clay plates have been approximately determined. It is demonstrated that for values of Biot numbers less than one, for Lykov criteria value of 0.05–0.13 and for Posnov criteria value of 0.03–0.08 for drying modes with a temperature of 90–120 ° C, the task of drying, as a heat and mass transfer process, is external, and internal transfer does not affect the conditions of interaction of the material surface with the environment.

This article discusses an innovative approach to heating systems in “smart homes” based on centralized heating with the utilization of secondary energy resources using a heat pump. The proposed heating system combines the advantages of traditional centralized heating and the efficiency of heat pumps. The article presents a calculated scheme, for which a temperature chart was developed. A methodology for calculating heat loads for both the traditional heating scheme and combined heat and power (CHP) with heat pumps is also proposed, and the necessary calculations were carried out. For clarity of the obtained data, a graph depicting the total steam load required for heating as a function of ambient temperature is constructed, as well as a graph showing the steam load as a function of the duration of the ambient temperature. The analysis of the data revealed that the use of heat pumps in CHP schemes reduces electricity generation by eliminating its production in the steam flow in the condenser. This facilitates the coverage of the electricity consumption schedule during periods of low demand for the integrated energy system. Additionally, integrating a heat pump into the heating system of the centralized heating system helps reduce energy dissipation and greenhouse gas emissions into the atmosphere, making heating more sustainable and environmentally friendly. Moreover, the proposed heating system for a “smart home” demonstrates high technical and economic performance, ensuring the investment attractiveness of such a project.","PeriodicalId":52141,"journal":{"name":"Energetika.
