Calculation of annual gas consumption

Annual gas calculation is one of the main indicators that must be taken as a basis for the development of gasification projects in settlements. According to the current norms and the standard, this indicator should be calculated at the end of the billing period, taking into account the main prospects for the development of gas consumers of concrete cities and towns.

Thus, in order to calculate the settlement period for a particular locality, it is necessary to take as a basis the plan for its development. Several types of gas consumption should be distinguished. These include gas consumption by apartments, communes, institutions and societies; And also for the purpose of heating or ventilation of premises.

The total volume of gas consumption depends mainly on the equipment used, the improvement of apartments and the number of people living in them, the quality of service to the population, the coverage of consumers by the hot water supply system and the climatic conditions of the area. However, taking into account all the factors necessary for the most accurate calculation Most often fails, expenditure rates are based, mainly on the basis of experimental data on the statistical analysis of gas consumption and experimental data on its consumption.

The most difficult thing is to normalize the consumption of gas in the apartments, due to the fact that it depends primarily on the quality of services provided to residents and the level of public services - canteens, cafes, buffets, restaurants and some other enterprises. Norms are made taking into account the average living conditions. To ensure that the resulting figures were as close to reality as possible, a correction is made for the data, the basis for which is the analysis of actual gas consumption when accounting for the development plan for settlements and the development of services. For example, building codes and norms contain the norms of annual gas consumption for living quarters, as well as industrial and communal-household enterprises. They are indicated taking into account the efficiency of diesel installations for the consumption of heat in the gas from a ratio of one conventional unit (or one person). Thus, at bakeries and bread-baking plants, gas consumption refers to one ton of manufactured products, and in a hospital - to one bunk. That is why the calculation of the annual consumption of gas by the bread factories must take into account the number of conventional units - the amount of bread consumed in the territory under consideration and the number of beds for the calculation of a similar indicator for hospitals.

An important role is also played by the development of the cities under consideration and the town-planning standards adopted in them. Calculating the rate of gas consumption for canteens, saunas, restaurants, it is necessary to take into account, first of all, the extent of coverage of these enterprises' services, as well as the use of other types of fuel (solid, liquid, hot water from CHP or steam, and electricity). It is also worth noting that a large part of the city's apartments are equipped with electric stoves. Having at its disposal data on the heat consumption, it is possible to determine the gas flow based on the efficiency of the operating heat source.

The industrial gas consumption is calculated for each particular enterprise. When transferring equipment to gas fuel, one should take into account its needs for fuel used before the transition, as well as changes affecting its efficiency. Also, when recalculating, it is necessary to take into account the qualitative improvement of technology, as well as the reduction in gas consumption due to the high quality of gas fuel.
