焦油一次汽化温度计算方法的探讨

Exploration for the Calculating Method for Primary Gasifying Temperature for Tar

利用相平衡原理得出的焦油蒸馏时一次汽化温度的计算方法,其结果与按经验公式的计算结果进行了比较,同时讨论了一次汽化温度与焦油馏分产率及二段蒸发器过热蒸汽用量的关系。

The calculation method for primary gasifying temperature during tar dis-tillation is gained with phase equilibrium principle. Its result is compared with the calcu-lated result with experienced equation. At the same time the relationship between prima-ry gasifying temperature and generated rate of tar fraction and overheated steam con-sumption of secondary evaporator.
