Numerical simulation of nitrogen injector in flare stack

简要阐述了引射装置在转炉干法除尘系统中的作用,指出工程计算中存在的问题,分析了氮气引射装置的工作机理。用计算流体力学的软件对放散烟囱及引射装置内流场进行了数值模拟,结果分析可为放散烟囱上的引射装置的设计提供计算依据。

The importance of nitrogen injector of flare stack in the dry dust removal system of converter gas and the problems existing in the project calculation were briefly pointed. The running medhanism of nitrogen injector was analyzed. The numerical simulation of flare stack and nitrogen injector internal flow was done by the computational fluid dynamics software. The results put forward the basis of calculation to design the nitrogen injector in flare stack.
