【摘要】 醇基燃料热值的准确与快速测试及计算,对醇基燃料应用发展具有重要意义。由于甲醇水混溶过程的特殊性,传统的热值测试方法和计算方法较为复杂并存在偏差。本文从影响醇基燃料发热值的诸多因素出发研究快速标定醇基燃料发热值的简易计算方法。鉴于尚无醇基燃料热值研究资料可查的情况,在查阅国内外关于其它燃料测试研究和甲醇-水组合化学结构研究资料的基础上,通过实验测试、误差分析、假设模型模拟等方法对影响醇基燃料热值的浓度配比、密度变化、混溶过程的放热、高锰酸钾的稳定性等因素进行了深入研究,获得基于密度计算醇基燃料低发热值的公式。公式计算结果与研究修正的门捷列夫理论经验公式的计算值对比表明：两者热值误差范围为0.25%-4.94%；研究成果为醇基燃料热值的快速测量提供了理论基础。更多还原

【Abstract】 It is significantly important for application and development of methanol-based fuel (MBF)that how the calorific value of MBF can be rapidly measured and accuratly calculated. And nowadays, Because of the special nature of the process of methanol dissolved in water. it have always been two focal issues of dispute that how to solve complex and deviation of traditional test means and calculation method. So the fundamental properties of MBF were investigated by means of theory and experiment in terms of simplified calculation methods of its calorific value.In view of none of research data for MBF being checked,the formula of MBF calorific value based on its density affected by different concentrations,densities,exothermal phenomena and Stability of potassium permanganate in the process of being mixed have been acquired by means of further investigation of experimental test, error analysis and model simulation,on the basis of consulting similar research of other fuels and chemical structure of methanol-water group, and the calculation results in contrast with that of modified Mendeleev experience formulas show that:the average error scope is 0.25%-4.94%; The research results provides a theoretical basis for rapid test of calorific value.更多还原
