The main component of natural gas is ch4Methane, and small amounts of ethane, butane, pentane, carbon dioxide, carbon monoxide,Hydrogen sulfide, and the like. Is a clean energy source and is widely applied to glass melting furnaces. At present, most of the domestic production and combustion systems for float glass use natural gas, a spray gun matched with the natural gas spray gun is basically a natural gas spray gun, the flame length of the spray gun can be adjusted, but the flame is not completely combusted, an intersection angle is formed by the combustion-supporting air and the flame on the upper part of the natural gas gun, and the combustion-supporting air does not exist in the combustion space of the flame on the lower part, so that the combustion is not sufficient, and the energy consumption of the natural gas. In addition, the melting temperature is higher than the temperature of the ordinary float glass when the glass with high photo-thermal ratio is produced, the ideal effect cannot be achieved by using the existing float glass combustion system, and the purposes of energy conservation and consumption reduction are achieved in order to improve the complete combustion of natural gas. The combustion mode of the natural gas spray gun needs to be improved so as to improve flame combustion and reduce natural gas consumption. And the flame sprayed by the existing spray gun is straight, so that the heating coverage area is small.
