摘要：With intensified energy restructure in China, energy efficiency of various industrial furnaces and kilns fired by natural gas draws attentions of more and more researchers. In this article, a field test was performed for shuttle kiln popular in ceramics and refractory manufacture industry. The thermal efficiency, main heat loss, and the energy-saving potential were evaluated, and the defects of the existing kilns and improvement measure were clarified. The results show that the overall efficiency was only 13%–15%, if measured in terms of the entire heating period. The energy loss of flue gas accounted up to 50%; the effectiveness of air preheater was as low as only 30%; large amount of cold air infiltration was observed at the venting exit at the bottom of the kiln. The burner controls and gas flow within furnace remain to be optimized.
