Embodiment Construction

[0009] A method for oxygen-enriched combustion in a float glass melting furnace according to the present invention, such as figure 1 , figure 2 As shown, the purifier of the air separation nitrogen unit and the oxygen-enriched air from the fractionation tower are respectively connected to the buffer storage tank at normal pressure. Float joint workshop, after entering the workshop, the oxygen-enriched air main pipe is divided into two routes, respectively controlled by a pneumatic cut-off valve (synchronized with the combustion air), and led to both sides of the regenerator of the glass melting furnace, and then along 1 # ,2 # The center line of the small furnace leads to a branch pipe, and a control valve is set on the branch pipe, and then the oxygen-enriched nozzle is introduced into the soot cleaning door of the regenerator.

[0010] In order to keep the nitrogen production system unaffected and maintain a stable nitrogen supply, an atmospheric pressure buffer storage t...

Abstract

The invention relates to a method of combustion in float glass melting furnace with enriched oxygen, comprising compressing the oxygen-enriched air (usually evacuated) generated in the nitrogen making system of the float glass process line; introducing the air to the two sides of the glass-melting furnace regenerator, along the down lead branch pipe of the 1#-2# furnace central line, which equipped with the control flap; then introducing the air to the deashing door of the regenerator by the oxygen jet to mix with combustion wind, and realizing partial enriched-oxygen combustion effectively. Side jet is heat-resisting stainless steel rectangular pipe, the angle between the jet and furnace central line is 25-50 degrees, the jet is equipped with blowing skimmer. The invention can not only improve the heat efficiency in the furnace, but also can avoid the problem of partial high temperature on the top of the furnace and realizes the effect of reducing the oil consumption, increasing the production and reducing the emission of Nox.

Description

technical field [0001] The invention relates to an oxygen-enriched combustion-supporting method for a float glass melting furnace. Background technique [0002] In order to reduce energy consumption and reduce NOx emissions, at present, people have carried out the following experiments on oxygen-enriched combustion in float glass melting furnaces: ①The combustion-supporting air method of introducing oxygen-enriched air into the combustion-supporting air main pipe. Due to the unreasonable distribution of oxygen-enriched air in the kiln, there will be dome burning flow, which will endanger the life of the furnace, and the experiment will be interrupted; ②Use the oxygen-enriched spray gun method. However, because the oxygen-enriched air temperature is too low, the nitrogen supply pressure fluctuates too much, which affects the continuous implementation of the method. Due to the continuity of float glass production (the kiln period is generally 5-10 years), and the transformati...
