摘　　要：通过分析排烟系统烟层平均温度计算结果,表明了在工业抗爆建筑中,烟层平均温度对操作间、工程师站等辅助房间净高会产生一定程度的影响。根据房间净高、设计清晰高度以及烟层平均温度之间的关系,并通过实际项目分析,可以测算出烟层平均温度不超过280℃时所需房间最小净高要求。Through the analysis of the calculation results of the average temperature of smoke layer in the smoke exhaust system, it is shown that the average temperature of smoke layer has a certain degree of influence on the net height of auxiliary rooms such as operation room and engineer station in the industrial anti-explosion building. According to the relationship between the room height, the design height and the average temperature of the smoke layer, and through the actual project analysis, the minimum room height required when the average temperature of the smoke layer does not exceed 280 ℃ can be calculated.
