㈠ 天燃氣鍋爐房防爆裝置都有什麼
防爆燈，防爆聲光報警器，防爆電氣控制設備，輸送氣體管道上的防爆儀表，
㈡ 燃氣鍋爐電器設備，燃燒機頭，有具體的防爆要求嗎有沒有標准或法律依據。
在燃氣鍋爐周圍的一定范圍內，所用電氣要用防爆電氣，鍋爐設備的輸氣管道有閥門，有法蘭，這些地方都有可能會有氣體泄漏，設備有防爆要求。
㈢ 燃氣鍋爐房 是不是防暴區
GB50016 第3/3/12說明在有明火的設備附近不劃分為防爆區。城鎮燃氣規范也規定鍋版爐房為丁類權，不劃分防爆區。GB50058第2。2.2也有此規定。因為在這些區域光一個電氣防爆沒有意義，你都有明火了還用得著電氣那點小火花來點燃？所以，一般不劃分為防爆區，但裝備氣體報警，防爆事故通風設施（事故通風要防爆是因為事故是濃度是已達到爆炸極限）。
㈣ 求一位大俠幫忙把論文翻譯成英文~100分 謝謝 燃氣鍋爐房的電氣防爆設計 摘 要：通過分析燃氣鍋爐房事故原
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 電氣設備的防爆措施有那些
選用專用的防爆電氣設備 有隔爆的 本安的 正壓的 通常設備用隔爆的回 儀表用本安活或增安的 具體等級答根據現場可燃物類型和點燃溫度決定 參見GB50058 《爆炸和火災危險環境電力裝置設計規范》
㈥ 燃氣鍋爐房鍋爐間電氣設備要求防爆嗎
一般情況下，燃氣鍋爐房的電氣設備是沒有防爆要求的。按要求做好管道的防靜電接地就足夠了。
㈦ 電氣設備的基本防爆措施有哪些
電氣設備的防爆措施，我理解為防爆形式，也就是防爆標志。
防爆電氣的專防爆標志有：1、隔爆屬型Ex d；2、充砂型Ex q；3、增安型Ex e；4、澆封型Ex m
5、正壓型Ex p；6、無火花型Ex n；6、本安型Ex ia；7、油浸型Ex o；8、特殊性Ex s；
9、粉塵防爆型ExtD

㈧ 燃氣鍋爐控制櫃是否必須採用防爆
在鍋爐間內必須是防爆櫃，在其他設備房（設備房與鍋爐間用防火門隔開）可以不使用防爆的。
㈨ 燃氣鍋爐房電氣必須防爆嗎
室外燃氣鍋爐電氣設備不用考慮防爆。只有在燃氣分配站區域的電氣設備要考慮防爆。
㈩ 天然氣鍋爐房內電氣專業哪些設備需採用防爆型
