Calculation of caloric content of gas is required, as a rule, to owners of houses and cottages for settlings with suppliers of gas. Natural gas in this case is used for maintenance of heat indoors and water heating, and these utilities are estimated at Gcal.
It is required to you
- Gas meter, gas calorimeter, standard of consumption of gas.
Instruction
1. Take readings from the gas meter. Write down the obtained data on the used cubic meters. To learn what amount of energy you consumed, it is necessary to increase the taken readings by fuel caloric content. Natural gas — it is mix propane, butane and other connections. Therefore in different regions the specific heat of combustion of its cubic meter can fluctuate from 7.6 thousand to 9.5 thousand kcal. According to the order of Federal tariff service, the value in 7900 kcal for the gas extracted by Gazprom is used. At wholesale purchases the recalculation at aberrations is provided.
2. Transfer the received calories to larger units. calories. Or unit with nine zero. If you consumed 1000 cubic meters, then, considering possible fluctuations of caloric content of gas, at you it has to turn out from 7,6 9,5 Gcal. But such significant consumption for houses with individual coppers is not peculiar. Respectively, the owner of a cottage will pay only for some part of gigacalorie.
3. Use a gas calorimeter for exact determination of power consumption of natural gas. It is reasonable to do it at large volumes of consumption. Producers of such devices are guided first of all by large enterprises in the sphere of power, ferrous metallurgy, oil production, oil processing, etc. It is required not only for calculations, but also for optimization of a ratio gas-air in heating torches and for management of big gas streams.
4. Carry out approximate calculation of the spent gas calories in the absence of the corresponding metering device. In this case the payment according to the standard which represents the fuel volume established for different types of consumption is exposed to you. Increase its value by an average value of caloric content in 7900 kcal/m3. Receive amount of the used energy.
