Abstract
A study of the gas consumption modes of the subgroup “Enterprises of construction industry and architecture” of the regional gas supply system, as well as the production of sheet glass, which forms gas consumption in the subgroup by 94%, was carried out. The field type “daily gas consumption outside temperature” is set for the subgroup and the plant for production of sheet glass. This is a field with a weak dependence on the growth of daily gas consumption when outside temperature decreases and without an obvious stratification into temperature regions determined by the state of the heating system (“on” or “off”) and a significant vertical spread of daily gas flow at the same values of outside temperature. Additional factors affecting gas consumption were searched. The created database of 14 technological indicators over a seven-year period allowed to identify factors forming daily and annual gas consumption regimes using correlation-regression analysis. The importance of the “time worked by the line” factor and its contribution to the formation of the annual volume of gas consumption was assessed. Invention proposes a simplified method of estimating the rate of aging of furnace lining and wear of enclosing structures on the basis of a single-factor model of gas consumption from productivity by comparing the daily average annual values of specific gas consumption for sheet glass production with the same volume of output.
Highlights
Many years of world experience show that during the operation of furnace equipment the furnace lining is burned and the enclosure structures of the furnace body are worn, as a result of which more gas is spent to compensate for losses and maintain the parameters of melting modes [1, 2, 3]
The production of sheet glass as a consumer of energy resources is characterized by the complex nature of the relationship between energy and technology, when energy consumption is influenced by many technological factors

Summary
Many years of world experience show that during the operation of furnace equipment (glass, cement enterprises) the furnace lining is burned and the enclosure structures of the furnace body are worn, as a result of which more gas is spent to compensate for losses and maintain the parameters of melting modes [1, 2, 3]. During the operation of the furnace, its scheduled hot and cold repairs are carried out with further adjustment of melting process parameters, which allows to contain the rate of EE fall (growth of specific gas consumption per production unit output) in accordance with the approaches [8, 9 and 10]. In order to make a natural gas application, enterprises with gas furnaces in their process equipment must take into account the factor of "furnace lining burnout and wear of enclosing structures," as its disregard can lead to a significant error in the declared volume of gas even when the volume of output is maintained
