Fuel step adding apparatus of glass melter total oxygen combustion

Abstract

The invention provides a hierarchical adding device for total-oxygen combustion fuel of glass melting furnaces. The device mainly comprises a main fuel pipe (2), a combustion-supporting oxygen pipe (7), a main burner (11), minor fuel pipes (12), as well as valves which are connected with the bodies of the combustion-supporting oxygen pipe (7), the main fuel pipe and the minor fuel pipes and play a certain role in controlling and regulating, wherein the main burner (11) has a casing-type structure and is sleeved with the body of the right part of the main fuel pipe (2); two minor fuel pipes (12) are provided, are symmetrically distributed on two sides of the main burner (11), and are parallel to the main burner; and the right end of the body of the combustion-supporting oxygen pipe (7) is connected and communicated with the main burner through a bent pipe. The device regulates the length, coverage area, temperature and other parameters of flame by adjusting the amount of fuel used between the main burner and the two minor fuel pipes so as to ensure the complete combustion of the fuel, has the advantages of saving energy, reducing emission, benefiting environmental protection and the like, and is especially applicable to total-oxygen combustion glass melting furnaces which takes natural gas as fuel.

Description

technical field [0001] The invention relates to the field of oxy-fuel combustion in glass melting furnaces, in particular to a device used in the combustion method of oxy-fuel combustion in glass melting furnaces. Background technique [0002] Glass melting furnace is the key thermal equipment for glass production. With the rapid development of the glass industry and the continuous improvement of the quality of refractory materials, the melting temperature of glass is also getting higher and higher, some of which are close to 1600 ° C, and the production scale is constantly expanding. Glass melting is an important part of energy consumption in the glass production process. With the energy shortage in the world, energy saving and emission reduction have been paid attention to by governments of all countries. At present, improving energy efficiency, reducing environmental pollution, and improving glass quality have become a topic of concern to the world's glass industry. Ba...
