Use a gas gas furnace used in glass industry in China began early, most applications of this gas companies are used to produce glass solute liquid, gas and other fuels and cold annealed glass is generally produced by furnace. Glass industry uses gas furnace are generally single-stage furnace, large gas production this gas stove, gas pipeline investment, tar can not be recovered; cold gas is used, it will seriously pollute the natural environment of small gas furnace, and the recovery of tar poor quality, can not be used again. These shortcomings have seriously hampered the further application of producer gas. A glass factory in Shanxi in 1989 began to take the lead in the single-stage gas furnace to a two-stage gas furnace. And they applied the advantages of the new flexible furnace, upper gas to remove tar gas form for annealing glass, while the lower section of the gas to the hot gas in the form of a glass melting furnace as fuel. In addition, in 1995, Hangzhou, a glass factory and the two on the lower section of the mixed gas furnace gas, coal gas as a heat application has been successful. Application of the results of these two examples are illustrated: later changed to two furnaces, gas heat value increased a lot, about 10% -15%, and the gas pressure is relatively stable single-stage gas furnace, significantly reducing gas pipeline blockage and environmental benefits have been greatly improved. For enterprises, energy consumption is to increase economic efficiency, minimize production costs, maximize profits. Thus an efficient use of fuel becomes very important. In the glass manufacturing process, fuel costs than 1/3, so improving fuel efficiency, the use of two furnaces is very effective. Hot gas system two gas furnace: When using single-stage furnace, due to higher gas dust content and condensed gas in the heavy tar mixed together, adhering to the inner wall of the hot gas pipeline, forming After another thick layer of sticky and hard deposits, it is difficult to blow or scrape, under normal circumstances dual-stage gas furnace, running three months, significantly increased resistance tube gas pressure from the gas furnace exit Before the switch to gas, can reduce about 40% -50%, so the average 3-4 months, you need a hot gas pipeline, the pipeline needs to burn every time a class, it will affect the normal production shifts 3-4 gas stoves, but also pollute the environment. While two-stage furnace, due to less amount of gas in the dust, and essentially free of tar, even during operation, the hot gas in the pipe wall will be part of the soot deposition, however, this part of the soot loose texture, easily removed.
