The work is devoted to the urgent problem of using an alternative energy source of biomethane for gas supply to settlements. The effective use of biomethane in gas supply systems requires scientific substantiation, considering the entire range of technological parameters and operating conditions. The methods of graphs and parametric optimization are used to minimize the total reduced costs to the gas supply system to carry out the research. Based on the analysis of gas consumption by the municipal districts of the Belgorod region, a graphical dependence is built and an expression is obtained to determine the annual gas consumption by the population on the population size. The calculation of the mass of organic waste and the density of substrate formation is made, on the basis of which the potential for biomethane production in the municipal districts of the Belgorod region is determined. It has been established that the potential volume of biomethane in the Belgorod region is 633194 thousand m3 / year, or 11% of the total gas consumption. A diagram of the location of biomethane plants and gas pipelines for supplying biomethane to gas networks has been built. The optimal values of the technological parameters of the biomethane gas supply system have been established: the operating range of the biomethane plant depending on the substrate formation density, the length of the gas network for biomethane supply, depending on the gas consumption density.

Copper pipelines are widely used while designing modern heating systems, water and gas supply of residential buildings and these pipelines have a number of advantages in comparison with steel and plastic pipelines. The main reason for limited use of copper pipes is their cost which is practically twice as much as cost of steel pipes, and four times higher than the coat of polypropylene pipes. Modern design standards in Belarus do not contain specific requirements for calculation of copper pipelines. Therefore hydraulic calculation of heating systems has been considered and analyzed on the basis of norms of Russian Federation. The drawback of all theoretical calculations presented in Russian standards is their abstraction from general laws of fluid and gas mechanics. For this reason theoretical foundations of hydraulic calculations for all pipelines have been considered and expressions have been given for determination of pressure loss due to friction and in local loss. Main flow regimes have been considered on the basis of I. Nikuradze’s experiments in order to determine linear losses and dependences for determination of friction coefficient in laminar, transient and turbulent modes have been presented in the paper. Values of local loss coefficient for main pipeline elements are given for calculation of pressure loss and the paper also shows determination of value z with due account of equipment capacity. An analysis of nomograms presented in Russian norms and researches has been carried out; shortcomings have been revealed and the ways directed on their perfection have been found. Nomograms for calculation of specific pressure losses in heating systems and internal gas supply have been constructed on the basis of natural gas and propane with due account of dependences presented in the paper. Nomograms for finding equivalent length of a single local loss have been constructed for calculation of internal gas supply systems.

Fuel-power supply systems are priority areas of engineering services. They account for large capital investments and costs of energy resources. An energy supply system based on LPG provides a high level of diversification and autonomy. This article presents recommendations for determining the basic technological parameters of liquefied petroleum gas tanks. The recommendation are intended to improve the efficiency of the tanks. The economic-mathematical model of optimizing underground tanks considers own evaporative capacity of tanks, their mutual thermal effect, as well as the temporal dynamics and unstable cost factors. The model allows for revealing the optimum technological parameters of installations: a single tank volume, the number of tanks in a group installation, the calculated level of gas tanks fill up before next refueling, depending on the volume of gas consumption.

Investigation of the structure and the functional patterns of the regional gas supply systems is necessary for addressing a number of operational tasks, the main ones being the following: preparing requisitions for the planned volume of gas deliveries, project design for development and reconstruction of gas supply systems and gas storage facilities, developing of functional gas tariffs for different groups of customers. The regional gas supply system is considered from the standpoint of system analysis and presented as a complex dynamic system consisting of several subsystems. The balance structure of gas consumption in the region for the ten-year period and the patterns of daily gas consumption in the region depending on the average daily outdoor temperature for the two-year period have been studied. It is discovered that the power economy, industry and agriculture account for the largest share in the total gas consumption. The values of correlation coefficients between the outdoor air temperature and gas flow rate according to the elements of the balance structure are calculated. For the daily values of gas consumption for the needs of the population and housing-and-communal services, the highest correlation coefficient between the studied characteristics R is noted = (–0,98‒(–0,96)). Analysis of the matching fields of daily gas consumption in the region to the daily average temperature over a given one-year timeframe made it possible to identified two key areas, viz.: the area of operation of the heating system and the area of positive temperatures (the cheating system is off). For each of the areas, the dependences of the daily gas flow rate on the temperature and the effect of temperature changes on the gas consumption alteration were determined. It was found out that the temperature range from 0 to 10 °C corresponds to the zone of uncertain state of the regional gas supply system, since two areas overlap in this zone, viz.: the area of operation of the heating system and the area of positive temperatures.

The article shows the relevance of hierarchical modeling in substantiating the optimal development of the gas industry in modern conditions. The questions of aggregation of calculation schemes of gas supply systems are considered. A set of mathematical models is proposed that allows us to consider it at three levels of the hierarchy, taking into account the improvement, refinement and detail of the information base being developed. Models are considered: 1) optimization of the structure of gas supply systems; 2) optimization of se-zone gas consumption, analysis and synthesis of reliability; 3) optimization of parameters of the main gas-wire taking into account reliability. The created information base on gas supply systems of the Russian Federation includes dynamics of development of demand for natural gas in the domestic and foreign markets, aggregated technical and technological, cost and reliability characteristics of system objects (main gas lines, fields, underground gas storage facilities) and forecasts of gas production. On the basis of mathematical models, studies of the development of multi-level gas supply systems in Russia for the period up to 2030 are performed: the rates and directions of development of the gas transport structure, commissioning of new fields and optimal gas flows through the Russian Federation are substantiated. A systematic assessment of the means of regulating seasonal unevenness of gas consumption and the means of ensuring the reliability of the North-Western district of the Russian Federation was carried out.

There are investigated the influence of operating pressures in the gas supply system on the level of such energy indicators as efficiency, gas flow and gas overrun by gas equipment in residential buildings. There is established a relationship between the values of operating pressures in the gas supply system and the gas consumption level of household appliances. The causes of insufficient pressure in the gas networks of settlements are analyzed in the article. There is also developed an algorithm for calculating the change in the efficiency of gas appliances depending on the operational parameters of the gas network. It has been found that the most efficient operation of gas appliances is observed at an overpressure at the inlet of gas appliances of about 1200 Pa.To ensure the required quality of natural gas combustion among consumers and minimize gas consumption there are justified the following measures in the article: coordinating a domestic regulatory framework for assessing the quality of natural gas with international norms and standards; improving the preparation of gas coming from local wells before supplying it to gas distribution networks; auditing low pressure gas pipelines and reconstructing areas affected by corrosion; ensuring standard gas pressure in the network for the normal operation of domestic gas appliances; stating quality indicators of natural gas combustion by gas sales organizations.
