The present utility model belongs to the technical field of glass kilns, and specifically relates to a glass kiln system that utilizes the waste heat of an annealing kiln and the heat dissipation of a furnace body to increase the temperature of combustion-supporting air, comprising a glass kiln and an annealing kiln. The glass kiln is connected to a left heat storage chamber and a right heat storage chamber on both sides, respectively. A heat storage area is provided below the glass kiln and between the two heat storage chambers. Air is sucked from the heat storage area and introduced into the glass kiln as combustion-supporting air; exhaust air from the annealing kiln is also introduced into the glass kiln as combustion-supporting air. The present utility model effectively increases the temperature of the combustion-supporting air by combining the heat of the annealing kiln exhaust air with the heat dissipated by the glass kiln, which is significantly better than using furnace bottom air or annealing kiln exhaust air alone. The increase in the temperature of the combustion-supporting air directly reduces the melting unit consumption of the kiln, thereby reducing energy consumption.
