INTEGRATION OF OPERATION OF REGENERATORS OF GLASS FURNACES

Abstract

The material of the article relates to the glass industry, namely to equipment for cooling the roof of regenerators of glass melting furnaces and can be used in the construction of new or reconstruction of existing regenerators.
 When the refractories of industrial glass melting furnaces are destroyed, an intensive decrease in the wall thickness of the melting basin occurs, which leads to a significant increase in the temperature of the outer surface of the walls and, accordingly, an increase in heat losses. The maximum destruction of the refractory masonry of the walls of the melting basin is observed at the level of the mirror of the melted glass. There is uneven wear along the height and perimeter of the pool. The rate of destruction of the masonry is determined by the stability of the used refractories, the temperature regime of glass melting, and the design features of the units.
 The technical task of the article is: to increase the service life of the refractory masonry of the glass furnace regenerator roof; utilization of the heat of the outer masonry surface of the regenerator roof, as well as improvement of its cooling system by using water cooling of the outer surface of the regenerator roof; saving fuel consumed to heat the same amount of coolant in boiler equipment.
 The proposed cooling of the outer surface of the regenerator roof makes it possible to: reduce the temperature of the outer surface of the roof to the level of 30 °C and at the same time make the most of the heat of the outer surface of the regenerator roof, which has not been used before, for example, to obtain hot water from a heat supply system, and this makes it possible to save fuel costs, which are necessary for the operation of boiler equipment to heat the same amount of coolant; to ensure a more uniform distribution of temperature fields over the entire plane of the regenerator roof by using flat collectors of a special design, which, in turn, makes it possible to slow down the process of destruction of the refractory lining of the regenerator roof. The thermocouples installed in the pipelines make it possible to monitor the change in the temperature of the coolant in the collectors, and in the event of an increase in the surface temperature of the collectors, the automation increases the flow of the coolant in the pipelines. The collectors are equipped with pressure valves, when the temperature of the coolant in the collector is above 100 °C, it can boil in the collector and then the pressure valve equalizes the pressure in the collector.
