Thermo-Chemical Regeneration Design for Energy Saving and Emission Reduction of Glass Industry Furnace

Abstract

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
