關於燃油熱風爐使用時要做到著火的預防

熱風爐屬於特種設備，使用不當可能引起嚴重的後果，造成不必要的損失，為瞭做瞭使用燃油燃氣熱風爐時起火的預防，熱風爐房的位置也是很重要的，熱風爐房不要建在建築群內，要建在建築的下風與側風方向，地上熱風爐房以門窗泄壓為主，地下熱風爐房利用機器吊裝孔、排煙豎井作為爆炸泄壓面積，同時可在主機房四周墻面或頂面內壁以及柱子的迎爆面上安裝爆炸泄壓板，降低燃氣爆炸時所產生的爆炸壓力峰值，降低爆炸時開釋的能量對主體結構的影響，保護主體結構。
Hot-blast stove belongs to special equipment, improper use may cause serious consequences and cause unnecessary losses. In order to prevent fire when using oil-fired gas-fired hot-blast stove, the location of hot-blast stove house is透水地坪 also very important. Hot-blast stove house should not be built in the building group, but should be built in the direction of downwind and cross-wind of the building and on-ground hot-blast stove. The room relieves pressure mainly by doors and windows, and the underground hot blast stove room uses machine hoisting holes and smoke exhaust shaft as explosion relief area. At the same time, explosion relief plates can be installed on the wall or top inner wall around the main room and on the explosion face of the pillars to reduce the peak explosion pressure generated by gas explosion and the energy released during explosion to the main body. The influence of body structure protects the main body structure. 要保障熱風爐房的通風性，每小時6-10次換氣，油箱室按10-15次換氣，油蒸氣比空氣重，風口要集中在機房下部，按下部排風量為2/3總排風量、上部按1/3總排風量設置風口。送風排風管道穿越樓板及隔墻處應設置70℃自動封閉的防火閥，燃燒室內經燃燒後的廢氣通過管道排向豎煙井，煙氣利用熱壓抬升原理排至室外。一般情況下設備外排餘壓僅一公斤壓力左右，故設置過渡管道時應留意管內流速不宜過大，以5-6m/s為宜，以防止排出煙氣溫度過高或存在明火，每臺熱風爐排煙口處應設置280℃時能自動封閉的防火閥。煙囪口應設有多層金屬濾網，防止有高溫固化的各類物質顆粒落到可燃物上引起燃燒。
To ensure the ventilation of the hot-blast stove room, 6-10 air exchanges per hour, 10-15 air exchanges in the fuel tank room, the oil vapor is heavier than air, and the tuyere should be concentrated in the lower part of the engine room. The tuyere should be set up according to the lower part of the exhaust air volume of 2/3 and the upper part of the engine room according to 1/3 of the total exhaust air volume. The air supply and exhaust pipes should be equipped with 70 C self-closing fire-proof valves when they pass through the floor and partition walls. The exhaust gas from the combustion chamber is discharged into the vertical flue shaft through the pipes, and the flue gas is discharged outdoors by the principle of hot-pressure lifting. In general, the residual pressure of the equipment is only about one kilogram. Therefore, when setting up the transition pipeline, it should be noted that the flow velocity in the pipeline should not be too high, and 5-6m/s is appropriate to prevent the excessive temperature of the exhaust gas or the presence of open fire. Fire-proof valves which can be automatically closed at 280 C should be installed at the exhaust port of each hot blast stove. The chimney mouth should be equipped with a multi-layer metal filter to prevent high-temperature solidified particles of various substances from falling on combustible materials and causing combustion.
熱風爐使用的燃料油屬於非導電體，通過油管、過濾器、泵等設備活動時，接觸與分離的現象連續發生會使被輸送的燃油帶電並聚積電荷，到一定程度就會發生火花放電，對於空氣中含有油蒸氣的機房其危害是顯而易見的。對接觸燃油的設備容器和管道實行接地可減少電荷向地殼泄漏的電阻，加快油中電荷開釋消除火花放電的可能性。
Fuel oil used in hot blast stove belongs to non-conductive substance. When the equipment such as tubing, filter and pump is moving, the phenomenon of contact and separation occurs continuously, which will electrify and accumulate charges of the transported fuel, and spark discharge will occur to a certain extent. The harm to the room containing oil vapor in the air is obvious. Grounding equipment containers and pipelines contacting fuel oil can reduce the resistance of charge leakage to the earth's crust, accelerate the release of charge in 印花地坪oil and eliminate the possibility of spark discharge.
常用的沒箱一般有圓柱形、橢圓形，需要機房隔開，土建圍護結構的耐火等級不低於二級，油箱、油泵間不應向鄰室開窗，其對鄰室開門應為甲級防火門。中間油箱需在室外設置緊急泄油容器，以便起火時排出油源。對燃油可能發生泄漏的地方應設置油溝井引至集中點定期排放，油泵配套的電機應選用防爆型電機。使用熱風爐時安全是第一，要按照熱風爐的相關規定來操作熱風爐。
Usually, there are cylindrical and elliptical tanks, which need to be separated from the engine room. The fire resistance level of the civil envelope structure is not lower than the second level. The windows should not be opened to the adjacent rooms between the fuel tank and the oil pump. The doors to the adjacent rooms should be Class A fire doors. The intermediate oil tank needs to install an emergency oil drain container outside, so as to discharge the oil source when the fire occurs. Where fuel leakage may occur, oil ditch wells should be set up to discharge regularly at the centralized point, and explosion-proof motors should be selected for matching oil pumps. When using hot stove, safety is the first. Hot blast stove should be operated according to the relevant regulations of hot blast stove.
