Abstract
"Emissions of pollutants are of great public concern due to their impact on the environment and human health. There is an acute issue of saving energy resources while reducing harmful emissions during the combustion of various types of fuel. Used oil, which consists mainly of hydrocarbons, is an excellent alternative for partial or complete replacement of typical design fuels does not contain the heavy residual fraction characteristic of heavy fuels. This article provides an overview of alternative fuel combustion technologies. The review focuses on the principles of operation, key technologies in the field of used oil combustion. As an alternative to existing technologies on the market, an innovative design of a swirl burner for burning various types of fuel is presented in comparison with the closest analogue in terms of design and characteristics. The main advantages of using the innovative design of the burner are substantiated. The conducted literature review and analysis will be useful for further study of the efficient combustion of used oil. Keywords: combustion, vortex burner, fuel-air mixture, vortex, alternative fuel, used oil."
