Interchangeability of various combustible gases and adaptation of gas-using equipment for their efficient combustion

Abstract

Abstract The article presents the results of studies, the purpose of which is to substantiate the possibility of using a wide class of different combustible gases in one gas-using equipment and to develop recommendations for changing the design and operational parameters of such gas-using equipment in the event of a transition from one type of non-interchangeable combustible gases to another. The methodology of the work is based on a critical analysis of the available data on the issue of interchangeability of combustible gases, as well as our own theoretical and experimental studies. Dependencies have been obtained that permit to determine the possibility of switching gas-using equipment from one type of gas to another. Recommendations have been developed on the permissible content of hydrogen in a mixture with natural gas, ensuring the efficient, safe and environmentally friendly use of such fuel in household and industrial heating devices. Scientific and practical results of the work permit to carry out a low-cost reconstruction of gas-using equipment from one gas to another, including the transition to combustible gas containing hydrogen.
