摘　　要：根据目前梭式窑的能耗现状,分析了蓄热式燃烧技术应用于梭式窑的可行性。采用蓄热式燃烧技术对一台45m3的梭式窑进行了技术改造,并进行了工业应用实验。实验中采用60s的换向周期,换向过程引起的温度波动不大于5℃。采用蓄热式换热器后排烟温度一直维持在40～100℃之间,烧制完成后蓄热式梭式窑较传统梭式窑节能26.8%。由于窑内温度分布均匀性提高,烧制出的产品的色泽也得以提升。The application feasibility of regenerative combustion technology on the shuttle kiln was analyzed considering the current energy consumption of shuttle kilns. The regenerative combustion technology was adopted to carry out modification on a shuttle kiln with the scale of 45m3, and the industrial application experiment was conducted as well. In experiment, the switch time was set at 60 seconds, so that the temperature fluctuation due to the switch period varied no more than 5 ℃ . When the regenerative heat exchanger was put into operation, the exhaust gas temperature remained within 40- 100℃ . The regenerative shuttle kiln saved energy by 26.8% more than the conventional shuttle kiln. The color of the product was improved due to the enhancement of uniform temperature distribution within the kiln.
