Abstract

The influence of temperature and partial pressure on the dissociation of carbon dioxide and water vapor is considered. An original analytical method for determining the degree of dissociation of CO2 and H2O is proposed. The calculation of dissociation parameters was carried out in relation to the conditions of gas combustion in a glass furnace. It has been established that the temperature range of 1500‒1800 oC, corresponding to the operating conditions of glass melting furnaces, is characterized by a relatively low degree of dissociation of CO2 and H2O: 4.23 and 1,26 %, respectively. As a consequence, the relative heat costs for dissociation are insignificant and do not exceed 2,48 %. The degree of dissociation and heat consumption for the endothermic effect increase most intensively at the temperature of the gas combustion products above 1800 °C.
