摘要
结合发生炉煤气的造气原理及不同的煤气冷却净化工艺,通过实例计算,揭示了不同发生炉煤气站煤气湿度的变化情况。同时指出煤气出站输送过程中,煤气通过管壁与外界环境换热,煤气中的部分饱和水冷凝析出,致使煤气湿度降低,此过程与出站煤气是否处于饱和状态无关。
Based on the gasification principle of generator gas and different gas coolingand purification processes and through practical calculation, changes in gas humidity at differentgas stations are revealed. It is also pointed out that during the gas delivery process, partof the saturated water in the coal gas condensates and precipitates with heat exchange betweenthe gas and external environment through pipe wall, leading to a decline of gas humidity. Thisprocess has no relationship with whether the purified gas is in saturated state or not.
