LPG+DME混合燃料的燃烧有效热量测试

The Testing of the Effective Combustion Heat of Fuel Mixtures of LPG and DME

采用家用LPG；燃气炉系统进行LPG＋DME混合燃料的燃烧有效热量测试。其结果表明，DME掺混比例受气候条件影响，综合技术、经济性考虑，DME掺混的适宜比例为20％；含20％DME的LPG＋DiME混合燃料在环境温度为20～25℃、30～35℃的有效热值分别是纯LPG燃料的91．05％、92．12％；DME的汽化可增强c5组分的汽化。

The effective combustion heat of fuel mixtures of LPG and DME was tested through using the domestic LPG gas furnace system. The results showed that the blending appropriate proportion of DME was 20% ,after comprehensive considering the technology and economy. And the blending proportion of DME was influenced by climatic conditions. The effective caloric value of LPG and DME fuel mixtures （con- taining 20% of DME） was respectively 91.05% and 92.12% of the pure LPG fuel＇s in the environmental temperature 20-25~C and 30 - 35~C. The vaporization of C5 components could be enhanced by DME.
