摘要: 燃料燃烧是玻璃工业碳排放的主要来源。热化学再生技术能够显著降低玻璃窑炉熔化能耗,减少碳排放。本文通过计算和模拟研究了玻璃窑炉热化学重整反应的可行性,设计参数对重整反应的影响,气体转化率对玻璃窑炉节能效率的影响以及重整反应时间对气体转化率和产量的影响。结果表明:甲烷与水蒸气自发反应温度大于617.82 ℃,与二氧化碳自发反应温度大于641.27 ℃;当重整反应温度大于1 000 ℃,反应时间超过10 s,甲烷与窑炉废气流量比(摩尔比)接近1时,热化学重整反应能够充分进行。

Abstract: Fuel combustion is the main source of carbon emission in glass industry. Thermo-chemical regeneration technology can significantly reduce the melting energy consumption and carbon emission of glass furnace. In this paper, the feasibility of thermo-chemical reforming reaction in glass furnace, the effects of design parameters on thermo-chemical reforming reaction, the effect of gas conversion on energy saving efficiency of glass furnace and the effect of thermo-chemical reforming reaction time on gas conversion and yield were studied through calculation and simulation. The results show that the spontaneous reaction temperature of methane and water vapour is more than 617.82 ℃, and the spontaneous reaction temperature of methane and carbon dioxide is more than 641.27 ℃. In addition, when the reforming reaction temperature is greater than 1 000 ℃, the reaction time is greater than 10 s, and the flow ratio (molar ratio) of methane to furnace waste gas is close to 1, the thermo-chemical reforming reaction can be fully carried out.

Key words: glass furnace, energy saving and emission reduction, thermo-chemical regeneration, energy efficiency, reaction temperature, reaction time
