A. 燃气锅炉房内的循环水泵一定要防爆型的吗
燃气锅炉房内的循环水泵一定要防爆型的，因为燃气锅炉用的是燃气，如果有泄漏，用普通泵可能有潜在危险。

2 accident reason analysis
Analysis of gas boiler room the cause of the accident, there are two possible: boiler ontology explosion, boiler room to explode gas explosion concentration and explosions.
Boiler blast furnace body, because be in, or flue gas mixture in explosive existence, when achieved by fire or explosion limit, boiler heat ignites causing accidents in itself. This point and the national norm of building fire system that conform to the relevant provisions. The actual current boiler proct has considered safe proction measures to avoid it. Qualified gas boiler itself has the explosion-proof process design, such as burner in abnormal situation automatic stop, self-control device also stop output fuel, Gas boiler combustion system higher automatization, including the gas pressure is high, low limit alarm protection, when the control logic where step does not meet the conditions set start corresponding interlock protection.
Avoid the boiler exploded possibility, but still ontology exist above another possibility, can avoid? How to avoid it?
Three measures
In fact in design, according to the boiler design code "and" automatic fire alarm system design code "GB50116-1998 etc standard, we have taken the following measures:
Natural gas pipelines valves, meter, may occur gas leak place, boiler room may proce gas storage proct area [relative density 0.8, it is to be in commonly roof area in these areas], all equipped with combustible gas concentration measurement alarm device, according to combustible gas concentration situation give out sound and light alarm signal and start exhaust fan, when leakage accident concentrations reach explosion limit of the lower limit 50% [this value for reference only], but also immediately close natural air intake ct total intake solenoid valves.
In the boiler room and a natural gas pipeline in and out of the room, the incident, but also with the smoke exhaust fan combustible gas alarm interlocking (start).
Electrical, instrument by cable selection TongXin, not less than 1.5 mm2 minimum section.
Gas radiation tube tube top or the nearby, the lightning rod should be installed above the pipe jacking tip should be not less than 3m, and its scope of protection tube top above not less than 1-m.
Gas pipeline should be static grounding device that, when pipeline as metal materials, and lightning protection or electrical engineering protective grounding wire connected, the measured resistance R more than 4 Ω. In pipe joints, such as the bend, flange, valve and pipe with good place cannot metal contact, also with metal soft line will be both ends jumper.
In the boiler room and a natural gas pipeline in and out of the room door, window take pressure measures.
According to the explosion and fire dangerous environment electrical device design specification "the laws 2.2.2 bar, accord with one of the following conditions may, when the explosion danger area: devin in item 3, in the process of proction use fire equipment near, A combination of these several measures can clearly, electrical equipment selection for the explosion.
At the same time according to the explosion and fire dangerous environment electrical device design specification "the laws 2.2.2 bar, accord with one of the following conditions may, when the explosion danger area devin: the first 2 items, and the highest possible flammable explosive chroma does not exceed 10% of the lower limit, Close air intake ct natural total intake solenoid valves, concentration exceed 10% of the lower limit explosion limit, boiler room near the roof area are gas storage proct area, so lighting lamps and lanterns and switch choosing is explosion-proof type.
4 conclusion
In gas boiler room electrical design, lighting choose explosion-proof lamps, other part adopts the explosion-proof type.

C. 焦炉煤气锅炉房墙壁上的轴流风机（防爆型）安装高度有要求吗，锅炉房净高8.5米，我安装在3.5米的高度合适
按中间偏下就好，参考防爆气体和空气比重理解，记得粉我
D. 燃气锅炉房电气必须防爆吗
室外燃气锅炉电气设备不用考虑防爆。只有在燃气分配站区域的电气设备要考虑防爆。
E. 燃气锅炉房 是不是防暴区
GB50016 第3/3/12说明在有明火的设备附近不划分为防爆区。城镇燃气规范也规定锅版炉房为丁类权，不划分防爆区。GB50058第2。2.2也有此规定。因为在这些区域光一个电气防爆没有意义，你都有明火了还用得着电气那点小火花来点燃？所以，一般不划分为防爆区，但装备气体报警，防爆事故通风设施（事故通风要防爆是因为事故是浓度是已达到爆炸极限）。
F. 燃气锅炉房锅炉间电气设备要求防爆吗
一般情况下，燃气锅炉房的电气设备是没有防爆要求的。按要求做好管道的防静电接地就足够了。
G. 天燃气锅炉房防爆装置都有什么
防爆灯，防爆声光报警器，防爆电气控制设备，输送气体管道上的防爆仪表，
H. 锅炉房泄爆面积
朋友，这个复规定在：GB50041-2008《锅炉房设制计规范》
15.1.2锅炉房的外墙、楼地面或屋面，应有相应的防爆措施。并应有相当于锅炉间占地面积10％的泄压面积，泄压方向不得朝向人员聚集的场所、房间和人行通道，泄压处也不得与这些地方相邻。地下锅炉房采用竖井泄爆方式时，竖井的净横断面积，应满足泄压面积的要求。
当泄压面积不能满足上述要求时，可采用在锅炉房的内墙和顶部(顶棚)敷设金属爆炸减压板作补充。
注：泄压面积可将玻璃窗、天窗、质量小于等于120kg/m2的轻质屋顶和薄弱墙等面积包括在内。
I. 燃气锅炉房应该设置防爆型感烟探测器吗
这个要听厂家意见，有的燃气锅炉就有探测器，一旦升温失败或者其他故障会自动警报的，
锅炉房可以装个防爆型感烟探测器，装上更好不装的话也不碍事。
