Due to the influence of lampblack, the exhaust hood and air duct of kitchen smoke exhaust system in commercial kitchens of hotels and restaurants will gradually accumulate oil contamination. When the oil stain in the smoke hood and air duct encounters an open fire, it is easy to burn and extend through the fan, air duct and other ways to cause a fire. Therefore, we should pay more attention to the safety of the use of the smoke exhaust system in Jinan kitchens. Here are some explanations.
Commercial kitchen cover fires are usually caused by open flames exposed in the flue to ignite residual grease in the flue. Under normal circumstances, operators usually pay attention to the cleanness around the stove surface, and are more likely to ignore the potential fire hazard of the flue directly above the stove. It will be arranged regularly because the flue is a relatively closed space.
If the flue is not cleaned in time, it is difficult to find open fire in time after the flue is inhaled to attract fuel. When it is found, the open flame will fill the whole flue, spread and guide. Close to the flue and miss the good time, causing the fire to expand.
As the soot brought by the lampblack is viscous, it will adhere to the flue to form oil stains. The grease itself is flammable. When it is exposed to fire or the temperature is too high, it will burn. If the commercial kitchen flue is not cleaned for a long time, grease will accumulate, especially in curved pipes, which is particularly easy to accumulate. Once burned, the flame will spread rapidly.
The cleaning contents of the kitchen smoke exhaust system include the surface of the main exhaust hood, the inner surface of the hood, the environmental protection network, the air inlet pipe, the water delivery panel, the fan, the centrifugal fan, the oil fume purifier, the vertical oil fume pipe, the parallel flue gas pipe, and the built-in fire hydrant.
The key part of cleaning is 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. We will focus on cleaning the interior of the parallel flue. The main method adopted is that people enter the flue for cleaning; The external vertical flue gas pipe is cleaned by manual disassembly and high-pressure cleaner.
The fire in the dining room kitchen is frequent, so it is particularly important to clean the lampblack pipe, exhaust hood, lampblack purifier, stove, fan, environmental protection and fan regularly. After years of construction, the company has accumulated rich experience, which can eliminate the fire hazards of users. Come to our website if you need http://www.jnqsg.com Consult!
