ОБОСНОВАНИЕ ПРИМЕНЕНИЯ КОМПОЗИТНЫХ БАЛЛОНОВ В КОММУНАЛЬНО-БЫТОВОМ ОБЕСПЕЧЕНИИ ПОТРЕБИТЕЛЕЙ ГАЗОМ

Abstract

The introduction of new advanced materials into gas supply practice leads to the creation of new products with improved qualities. For domestic use, along with traditional metal cylinders for liquefied petroleum gas, composite cylinders have recently been offered. Possessing a number of undeniable advantages, composite cylinders annually increase their share of presence in the field of bottled gas supply. However, the transition from traditional metal cylinders for the consumer should not be accompanied by a banal change of vessels, but requires a comprehensive, competent approach with justification for decisions made on the formation of a gas supply system for the consumer based on cylinders made of composite materials. Using the basic principles characterizing changes in the states of gas mixtures included in liquefied hydrocarbon gas, the characteristics of heat exchange, the vessels under study, the principles of operation of gas-using equipment for the consumer, parameters are determined that form the basis for the competent use of composite cylinders for the consumer using liquefied gases of various brands. As a result of the research, the mass of gas for filling cylinders was determined, taking into account the seasonality of operation and brands recommended for domestic consumption, the process of heat exchange between the cylinder and the environment was studied, taking into account its operating mode and the uneven generation of the vapor phase in the daily cycle of operation to ensure food preparation and hot water supply to consumers, the optimal periods of continuous operation of an individual cylinder installation with different capacities of a sin-gle composite cylinder and the number of cylinder replacements in the annual operating cycle were determined.
