Abstract：Combined with the actual case,through the analysis of the explosive atmospheres of the gas‑fired boiler room and how to take measures to ensure its good ventilation,the gas‑fired boiler room is divided into non‑hazardous area according to the specifications. Combined with the lightning protection requirements of the specifications for the bleeder,several methods of lightning protection of the bleeder in the actual project are listed, and it is suggested to select the best.

Key words：gas‑fired boiler room;hazardous area;explosive atmospheres;well ventilation;source of release level;bleeder;protection against lightning;air‑termination rod

摘　要：结合实际案例，通过对燃气锅炉房的爆炸性环境分析，以及如何对燃气锅炉房采取措施保证其通风良好，从而根据规范将燃气锅炉房划分为非爆炸危险区域。结合规范对放散管的防雷要求，列举实际工程中放散管防雷的几种做法，并建议择优选取。
