[0002] Existing ceramic glazes and microcrystalline plate particles often use regenerative air combustion furnaces when melting. This type of furnace uses air combustion. 78% of the nitrogen in the air will inevitably be oxidized into nitrogen oxides in the high temperature furnace. Due to the nitrogen content Oxide furnace tail gas removal costs are high, which is difficult for enterprises to bear. They always discharge the furnace tail gas containing nitrogen oxides directly, causing serious air pollution; in addition, the thermal efficiency of the regenerative furnace fuel is low, and the regenerative chamber is wasteful.
