To determine the efficiency of biogas use in the existing industrial enterprises of the metallurgical industry of Ukraine and Zaporizhia region, in particular, the basic economic indicators of conversion of standard furnace equipment to biogas mixtures from various derivatives and sources available in the region are calculated. The technical feasibility and economic feasibility of using biogas mixtures as an alternative fuel for energy supply of thermal and heating furnaces of industrial enterprises on the example of a real object are determined. It is shown that to use low-calorie fuel in power equipment, taking into account its quality indicators, it is expedient both separately and in combination with traditional energy sources. It is revealed that the economic indicators of projects for the introduction of biogas technologies at metallurgical enterprises differ depending on many initial conditions, such as: sources of origin and chemical composition of biogas; characteristics of power equipment that is converted to such fuel; the proportion of natural gas substitution in the fuel mixture; etc. Based on the trend of constant growth in the cost of traditional energy resources, the introduction and use of their alternative and renewable counterparts in energy-intensive metallurgical enterprises is relevant and, with the right approach, cost-effectiveKeywords: energy efficiency, biogas technologies, biogas, natural gas, purification, enrichment, industrial furnaces, economic feasibility
