1·If the flue overdraws, all the heat goes right up the chimney.

如果风管抽风过度的话，热量就会从烟囱直接跑掉了。

2·The useful APDL(ANSYS parametric design language)technology was used in the finite element analysis and structural optimum design of the multi-flue chimney of a power plant.

利用ANSYS的APDL（参数化设计语言）的强大功能对某电厂多管式烟囱进行了有限元分析与结构优化设计。

3·The flow velocity limitation for different inner lining was proposed to ensure the safety and reliability operation of chimney for wet flue gas discharging.

建议了不同内衬应控制的烟气流速限值，保证排放湿烟气的烟囱安全可靠运行。
