Glass tank furnace with high melting rate

Abstract

The invention discloses a glass tank furnace with high melting rate. The ratio of the length of the glass tank furnace to the width of the glass tank furnace is 2.3-2.8. The glass tank furnace has the advantages that the area of the tank furnace is reduced and the length-width ratio of the tank furnace is optimized so as to reduce heat loss; reasonable liquid glass tank depth is designed to improve the bottom temperature of the tank furnace and guarantee the quality of liquid glass; a pure-oxygen burner and an auxiliary capacitor provides sufficient energy to increase the melting ability and heating efficiency of the tank furnace, and the energy consumption and the discharge amount of carbon dioxide are lowered greatly; furnace ridges at the bottom of the tank furnace increase the outlet temperature of the liquid glass, lower energy consumption, lower the furnace bottom temperature of an electrode area, prolong the service life of the furnace bottom and guarantee the increasing of auxiliary electric energy proportion; bubbling at the bottom of the tank furnace increases the return strength of the liquid glass and increases the melting ability and the quality of the liquid glass; to sum up, the melting rate of the tank furnace can be increased effectively, and the energy consumption can be lowered.

Description

technical field [0001] The invention relates to glass pool kiln technology, in particular to a glass pool kiln with high melting rate. Background technique [0002] At present, with the shortage of energy, the cost of thermal equipment with high energy consumption such as glass tank kilns is also getting higher and higher; at this stage, the aspect ratio of domestic unit kilns is generally controlled between 3-3.3, and its melting rate (melting rate It refers to the amount of glass melted by the melting area of ​​the unit kiln per square meter per day. The glass flow rate is the actual output of the kiln. An index of the level) is generally below 2.4 tons / day*square meter. Due to the backwardness of its equipment and combustion technology, and the kiln area is too large and the bottom temperature is high, there are low melting rate, high investment, high energy consumption, and poor operation. Shortcomings such as low efficiency and job yield. [0003] Therefore, in view o...

Problems solved by technology

[0002] At present, with the shortage of energy, the cost of thermal equipment with high energy consumption such as glass tank kilns is also getting higher and higher; at this stage, the aspect ratio of domestic unit kilns is generally controlled between 3-3.3, and its melting rate (melting rate It refers to the amount of glass melted by the melting area of ​​the unit kiln per square meter per day. The glass flow rate is the actual output of the kiln. An index of the level) is generally below 2.4 tons / day*square meter. Due to the backwardness of its equipment and combustion technology, and the kiln area is too large and the bottom temperature is high, there are low melting rate, high investment, high energy consumption, and poor operation. Disadvantages such as low efficiency and job yield

[0003] Therefore, in view of the above existing problems, it is urgent to design and provide a glass tank furnace with a high melting rate to solve the shortcomings of the existing tank furnaces such as low melting rate and high energy consumption.
