Landfill Gas as an Alternative Energy Source

Abstract

Purpose of research. With the increase of population and number of megacities, the consumption of various goods increases and the waste of which eventually turns into garbage. The growing amount of all kinds of waste every year and their negative impact on the environment is a global problem. However, with all existing methods of waste disposal, the least environmentally friendly method of waste disposal is used in our country - disposal by means of burial ground disposal at solid waste landfills. Landfills of solid waste are a source of landfill gas, the uncontrolled emissions of which have a negative impact on the environment. At the same time, the properties of landfill gas make it possible to use it as an energy source. The analysis of the problems рфму showт the relevance of the direction of using landfill gas as an alternative type of gas fuel, as well as the development of devices for its efficient combustion.Methods. The article discusses the impact of solid domestic waste (MSW) on the Earth's biosphere. The analysis of the global problem of waste disposal is carried out, solutions are considered. Based on the methodology specified in GOST 33998-2016 “Gas household appliances for cooking. General technical requirements, test methods and rational use of energy ”, we have carried out a study of the efficiency of the landfill gas combustion process in the developed design of a gas burner device equipped with a thermal splitter.Results. On the basis of experimental studies for a gas burner device of the developed design, the values of efficiency,% of the burner and the content of carbon monoxide (CO, mg / m3) in the combustion products have been obtained, depending on the length of the thermal divider.Conclusion. The results of experimental studies have shown the high efficiency of the original gas burner device when burning landfill gas.
