Іncreasing the efficiency of the use of natural gas in household gas stoves

Abstract

In Ukraine, about a third of the energy is obtained from burning gas (about 30 billion cubic meters of natural gas per year). More than half of this amount of gas is burned in the communal household sector, which includes the population. The largest number of devices intended for burning gas are installed in the population and are household gas stoves used for cooking. The total consumption of gas used by these devices makes up the main part of the gas used in the country in the summer period of the year. In connection with the significant increase in the price of energy carriers and the transition to paying for gas in units of energy, the issue of energy-efficient gas consumption is becoming more and more relevant. In this work, an analysis of the study of the use of gas at different pressures in domestic gas stoves is carried out. A comparison of the efficiency of gas use compared to the use of electrical energy is made. It has been determined that the optimal pressure in front of the gas stove burner, at which combustion has the most economical effect, is 2400 Pa. At this pressure, compared to electrical energy, efficiency increases by 20.8%. When the gas pressure deviates from 2400 Pa, there is a decrease in combustion efficiency, and at a pressure of 1800, the use of natural gas becomes economically impractical (compared to the use of electrical energy for cooking). Combustion of gas, ensuring the necessary completeness of combustion, has a positive effect on the environment as a result of reducing the content of carbon monoxide both in the indoor air of kitchens and in the environment of populated areas. Increasing the energy efficiency of burning natural gas will lead to a decrease in its consumed amount, and as a result, will positively affect the amount of payment for consumed gas, reduce the need for it and increase the level of energy independence of the state.
