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.

Ⅱ 鍋爐房防爆窗規范
摘要 由於國家對環保要求的不斷提高，以天然氣作為鍋爐燃料的燃氣鍋爐，已成為目前的普遍選擇，由於燃氣泄漏容易發生爆炸等危險，為了保證其在使用期間的安全，國家規定鍋爐房必須要符合燃氣鍋爐房防爆要求規范。
Ⅲ 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）。
Ⅳ 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。
Ⅳ 鍋爐房配電櫃需要防爆嗎
不管是燃煤鍋爐還是燃氣鍋爐，都需要配防爆配電櫃，如果是燃煤鍋爐，可能會有一氧化碳氣體生成，如果是燃氣鍋爐，如果泄露也很危險。鍋爐周圍屬於危險區域！
Ⅵ 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。
Ⅶ 燃氣鍋爐房內的循環水泵一定要防爆型的嗎
燃氣鍋爐房內的循環水泵一定要防爆型的，因為燃氣鍋爐用的是燃氣，如果有泄漏，用普通泵可能有潛在危險。

Ⅷ 鍋爐房防火防爆措施主要有哪些
鍋爐抄房的外牆、樓地面或屋襲面，應有相應的防爆措施。並應有相當於鍋爐間佔地面積10％的泄壓面積，泄壓方向不得朝向人員聚集的場所、房間和人行通道，泄壓處也不得與這些地方相鄰。
Ⅸ 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，
Ⅹ 燃氣鍋爐溫控閥需要防爆嗎
是防爆區，在鍋爐房設計規范上第13.2.2有說明，必須按《爆炸和火災危險環境電力裝置設計規范》來設定。而按《爆炸和火災危險環境電力裝置設計規范》第2.2.5條和第五節的內容，你就可以解決這個問題。結論為應該採用防爆的。PS:我們做的燃氣鍋爐房鍋爐間電氣和照明都採用防爆。
