商用厨房一般油烟道火灾都是由于明火被吸入烟道引燃烟道内残留的油垢所致。平时，操作人员一般会注意灶台周围的清理，而较容易忽视灶台正上方烟道的潜在火灾危险性。会定期安排由于烟道是一个相对封闭的空间，如果烟道清洗不及时，明火被吸入烟道引燃油污后将很难被及时发现，等到发现时，明火已充满整个烟道，蔓延并引着临近烟道的，错过时机，造成火势扩大。
Generally, the fire in the oil flue of commercial kitchens is caused by the open fire being sucked into the flue to ignite the residual oil dirt in the flue. At ordinary times, operators usually pay attention to the cleaning around the stove, and are more likely to ignore the potential fire hazard of the flue directly above the stove. As the flue is a relatively closed space, if the flue is not cleaned in time, it will be difficult to find the open fire in time after it is inhaled into the flue and ignites the oil stain. When it is found, the open fire has filled the whole flue, spread and ignited the adjacent flue, and missed the best time, causing the fire to expand.
由于油烟所带的烟尘有粘性，附着在烟道内形成油垢，油垢本身是可燃的，遇明火或温度过高，会燃烧。如果长时间未对商用厨房烟道进行清洗，油垢就会积压，尤其是弯曲式管道，特别容易积压油垢，一旦遇火燃烧，火苗很快会蔓延。
As the smoke carried by the lampblack is sticky, it attaches to the flue and forms oil dirt. The oil dirt itself is flammable and will burn in case of open fire or high temperature. If the commercial kitchen flue is not cleaned for a long time, the oil dirt will accumulate, especially in the curved pipes, which are particularly easy to accumulate oil dirt. Once the fire burns, the flame will spread quickly.
油烟管道定期清洗及保养，火灾隐患
Regular cleaning and maintenance of lampblack pipes to eliminate fire hazards
餐厅厨房火灾频发，定时进行油烟管道清洗、排烟罩清洗、油烟净化器清洗、灶台清洗、风机清洗、网清洗、风涡轮清洗显得尤为重要。
The fire in the dining room and kitchen occurs frequently, so it is particularly important to clean the oil smoke pipe, smoke exhaust hood, oil smoke purifier, stove, fan, environmental protection net and wind turbine regularly.
厨具清洗内容包括主排烟罩表面、烟罩内面、网、进风管、运水面板、风涡轮、离心风机、油烟净化器、竖立油烟管道、平行油烟管道、内置防火栓。清洗部位是主排烟罩内侧、网、进风管、主排烟罩上方的烟道内部。
Kitchenware cleaning includes the surface of the main smoke exhaust hood, the inner surface of the smoke hood, the environmental protection network, the air inlet pipe, the water delivery panel, the wind turbine, the centrifugal fan, the oil smoke purifier, the vertical oil smoke pipe, the parallel oil smoke pipe, and the built-in fire hydrant. The key parts for cleaning are the inside of the main smoke exhaust hood, the environmental protection network, the air inlet pipe, and the inside of the flue above the main smoke exhaust hood.
餐馆内的厨房油烟多，除了每天要擦洗烟道外，对于内部积压的油垢，少每60日要彻底清洗一次，才能有效火灾隐患。
The kitchen in the restaurant has a lot of lampblack. In addition to scrubbing the flue every day, the accumulated oil dirt inside should be thoroughly cleaned at least every 60 days to effectively eliminate the fire hazard.
