㈠ 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，
㈡ 燃气锅炉电器设备，燃烧机头，有具体的防爆要求吗有没有标准或法律依据。
在燃气锅炉周围的一定范围内，所用电气要用防爆电气，锅炉设备的输气管道有阀门，有法兰，这些地方都有可能会有气体泄漏，设备有防爆要求。
㈢ 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）。
㈣ 求一位大侠帮忙把论文翻译成英文~100分 谢谢 燃气锅炉房的电气防爆设计 摘 要：通过分析燃气锅炉房事故原
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.

㈤ 电气设备的防爆措施有那些
选用专用的防爆电气设备 有隔爆的 本安的 正压的 通常设备用隔爆的回 仪表用本安活或增安的 具体等级答根据现场可燃物类型和点燃温度决定 参见GB50058 《爆炸和火灾危险环境电力装置设计规范》
㈥ 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。
㈦ 电气设备的基本防爆措施有哪些
电气设备的防爆措施，我理解为防爆形式，也就是防爆标志。
防爆电气的专防爆标志有：1、隔爆属型Ex d；2、充砂型Ex q；3、增安型Ex e；4、浇封型Ex m
5、正压型Ex p；6、无火花型Ex n；6、本安型Ex ia；7、油浸型Ex o；8、特殊性Ex s；
9、粉尘防爆型ExtD

㈧ 燃气锅炉控制柜是否必须采用防爆
在锅炉间内必须是防爆柜，在其他设备房（设备房与锅炉间用防火门隔开）可以不使用防爆的。
㈨ 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。
