机械排烟温度对清晰高度的影响分析

Analysis of Influence of Mechanical Exhaust Temperature on Clear Height

本文从限制烟气平均温度小于280℃的角度,以工程中常用的轴对称烟羽流计算公式,反推出在不同建筑类别、不同热释放率条件下保证烟气平均温度小于280℃的清晰高度,并指出在执行规范时应注意的问题。

From the angle of limiting the average temperature of flue gas to be less than 280 ℃, this paper, based on the calculation formula of axisymmetric smoke plume commonly used in engineering, reversely deduces the clear height to ensure that the average temperature of flue gas is less than 280 ℃ under the conditions of different building types and different heat release rates, and points out the problems that should be paid attention to when implementing the code.
