摘要
采用精密型水流式燃气热量计测定天然气的发热量，并与组成分析计算的发热量进行了比对。结果表明：采用精密型水流式燃气热量计测定天然气的发热量，八次平行测定结果的相对标准偏差为0．19％，以计算值作为标准进行比对，二者之间的比对误差≤±1．51％，表明该方法精密度较高，且测定准确可靠。
The paper introduces a method for determining calorific value of natural gas by water-flow type precision calorimer of fuel gas, and the relative standard deviation of parallel determination for eight times is 0.19%. The neasured results are compared with the calorific values calculated by composition of natural gas, the result shows that the relative error isn't more than±1.51%. The precision of method is high and the measured result is accarete and credible.
