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.
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.
Regular cleaning and maintenance of lampblack pipes to eliminate fire hazards
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.
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.
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.
