《全国民用建筑工程设计技术措施暖通空调动力》4.4.4条对“锅炉房、直燃溴化锂制冷机房(简称直燃机房)的通风”要求:

  1 锅炉间、直燃机房、水泵间、油泵间等有散发热量的房间,宜采用自然通风或机械排风与自然补风相结合的通风方式;当设置在地下或其他原因无法满足要求时,应设置机械通风。

  2 锅炉房、直燃机房以及与之配套的油库、日用油箱间、油泵间、燃气调压和计量间,宜设置各自独立的通风系统,事故排风机应采用防爆型并应由消防电源供电,通风设施应安装导除静电的接地装置。

  3 锅炉房、直燃机房及配套用房的通风量应按以下确定:

  1)当设置在首层时,……燃气锅炉间、燃气直燃机房的正常通风量应≥6次/h换气,事故通风量应≥12次/h换气;

  2)当设置在半地下或半地下室时,锅炉房、直燃机房的正常通风量应≥6次/h换气,事故通风量应≥12次/h换气;

  3)当设置在地下或地下室时,锅炉房、直燃机房的通风量应≥12次/h换气;

  4)锅炉间、直燃机房的送风量应为排风量与燃烧所需空气量之和。

  《全国民用建筑工程设计技术措施暖通空调动力》,基本上是对《锅炉房设计规范》的引用,仅有少量的补充。因此,仍应以《锅炉房设计规范》和《城镇燃气设计规范》的规定作为燃气锅炉房的通风设计的基本依据。
