The smoke in the chimney of the fried chicken shop will exceed the standard. Because the fried chicken shop uses a lot of oil and gas, it will produce a lot of lampblack in the cooking process. Without proper ventilation and chimney equipment, these fumes will accumulate in the chimney and exceed the allowable emission standards. In addition, the lack of regular cleaning and maintenance of chimneys in fried chicken shops will also lead to the accumulation of smoke and harmful substances in chimneys, which will cause potential harm to human health and the environment. Therefore, in order to ensure the atmospheric environment around the fried chicken shop and the health of residents, the fried chicken shop should discharge in strict accordance with the relevant regulations, and regularly clean and maintain the chimney equipment.
