替代燃料二甲醚在陶瓷窑炉应用的可行性研究初探

Preliminary Feasibility Study on the Application of Dimethyl Ether as Alternative Fuel in the Ceramic Kiln

对陶瓷窑炉常用燃料从燃气的性能指标、热值、理论燃烧温度和成本各方面进行了对比分析,探讨了二甲醚作为替代燃料在陶瓷窑炉中的应用前景及存在的瓶颈问题。二甲醚燃气总体性能指标最优,并且在热值、理论燃烧温度和成本对比中具有明显优势,完全可以替代目前所使用的陶瓷烧制燃料。二甲醚的稳定供应和设备改造问题、二甲醚的燃烧过程和污染物排放的控制问题是替代燃料二甲醚在陶瓷工业应用的亟需解决的关键问题。

The performance index, calorific value, theoretical combustion temperature and cost of commonly-used fuels in the ceramic kiln were compared in this paper. The application prospects and the existing bottleneck problems of dimethyl ether（DME） as alternative fuel in the ceramic kiln were discussed. DME has the optimal performance index and the obvious advantages in the comparison of calorific value, theoretical combustion temperature and cost, indicating that DME can completely replace the currently used ceramic fuels. Solving the problems of steady provision and equipment modification, controlling the burning process and pollutant emissions may promote the application of DME as alternative fuel in the ceramic industry.
