    ENG: The results of determining the gas interchangeability criterion are presented. An analysis of the possibility of adapting existing gas combustion plants for the effective and stable use of a wide range of combustible gases is performed. It is shown that even natural gases from different deposits are not always interchangeable. Recommendations are developed that allow the use of even non-interchangeable gases on the same gas combustion equipment by changing the operating settings or slightly changing the design characteristics of the equipment. The results of the study of heat transfer in the combustion space when the composition of combustible gases changes and the associated changes in the emissivity of combustion products are presented. Recommendations are given on the organization of the combustion process of non-interchangeable gases, including by creating mixtures of combustible gases with the provision of the necessary interchangeability criteria. The purpose of the work is to study the possibility of effective combustion of alternative types of artificial and synthetic combustible gases, including hydrogen, as well as non-interchangeable natural gases in existing gas combustion equipment. Study of the properties of combustible gases characteristic of gas distribution systems of Ukraine, and their compliance with the inter-changeability criteria and gas combustion equipment manufactured and supplied for industrial and municipal purposes. The relevance of the issues of ensuring the interchangeability of gases is confirmed by the implementation of regulatory legal acts on the quality indicators of combustible gases and the efficiency of their use in the national legislation of Ukraine. The results of the study provide the possibility of a barrier-free gradual introduction of alternative types of gases and a gradual transition to the combustion of gases with hydrogen content without cardinal changes in the design of existing burners and their operating modes.
