Described melting pool is provided with at least one burner, is arranged on large arch or breastwork, and the flame of burner sprays towards glass batch, with both sides breastwork angle be 0-80 °, with 0 ° of gable wall or rear face wall angle;
Described flue be located on gable wall or the both sides breastwork of melting pool C district top on, or described flue is located on the both sides breastwork of top, melting pool A district; Described filling pocket is located on the both sides breastwork of top, melting pool A district, or described filling pocket is located on gable wall;
Described flue outlet is provided with a metallic recuperator, or described flue outlet does not arrange metallic recuperator.
Further, described A district, B district, C district are respectively at least provided with a burner.
Further, the A district of described melting pool and B district are provided with the vertical electrode being inserted at the bottom of melting pool of many rows, the electrode glass melt that submerges, and described melting pool B district and C district boundary are provided with bubbling device.
Technical conceive of the present utility model is: make burner face toward glass batch and glass metal burner oil and oxygen, make close glass batch and the glass metal of even touching of end high-temperature part in flame, reduce the distance between flame and glass batch and glass metal, improve heat transfer efficiencies, reduced energy consumption; The distance that has increased end high-temperature part and arch top refractory materials in flame, has alleviated the erosion to arch top refractory materials; Use electrode to carry out boosting and improved the melting capacity of kiln, significantly reduced the energy consumption of unit glass; The use of bubbling technology has strengthened the convection current of glass metal, and glass metal is played to homogenizing; In the situation that using metallic recuperator, can, to the waste heat recovery recycling of flue gas, reduce the loss of energy, reduce production costs.
The utlity model has that heat transfer efficiency is high, little to refractory corrosion, long service life, energy-conservation advantage.
