水蒸气供给量
1.
Based on calculation of vapor amount in gasification agent,such factors as atmospheric pressure,bottom air pressure,saturated temperature as well as original wet air temperature which may affect the vapor amount in the gasification agent are studied in this paper.
通过对气化剂中水蒸气供给量的计算,分析了大气压、炉底鼓风压力、饱和温度和原始湿空气温度等对气化剂中水蒸气供给量的影响:指出气化剂中水蒸气供给量随大气压和原始湿空气温度的增大而降低,随饱和温度的提高而增大,炉底鼓风压力、原始湿空气湿度及外界供应饱和水蒸气温度等,虽然对气化剂中水蒸气供给量有一定的影响,但就常压固定床煤气发生炉而言影响较小,可以忽略不计。

补充资料：水蒸气透过量
分子式：
CAS号：
性质：又称水蒸气透过量或透湿量。塑料薄膜或片材两侧存在水蒸气压力差时，在一定温度下透过的水蒸气量以g/(m2·24h)表示。用杯式法测量。装好试样的透湿杯放在一定条件的环境中，如相对湿度为90％±2％，温度28℃，进行水汽透过。杯中有干燥剂，可以认为水蒸气压力为零。经过一定时间，干燥剂吸收透过的水蒸气而增重，根据增重的量，水蒸气透过率WVT=24×△m/A·△t，式中△m是T时间内的质量增重，g；△t是质量增量稳定后，两次测重间隔时间，h；A是试样透过水蒸气面积，m2。
