摘要
经过较为严密的理论推导,提出了比较精确的自然通风反压式烟囱中烟气和可变间隙通风道中空气的沿程摩阻损失的计算公式。进而,以此为基础分析了文献[2],[4]中推荐的栩应计算式的误差。结果表明,本文提出的公式更适合于在工程设计中使用。
The author presents a relatively precise formula for calculating fluid frictional loss in a natural ventilation counter-pressure smoke stack after performing a strict theoretical deduction. On this basis the error of a corresponding formula recommended in Ref. (2) and (4) has bcen analysed. The result of this analysis has shown that the formula givcn by the author is morc suited for use in related engincering design
