kitchens

A large quantity of oily fumes is generated in fast food and Chinese restaurants from cooking oil kept at a high temperature in the kitchens. If these oily fumes are not properly abated, they can be a major source of organic emissions in some dense urban areas with a lot of restaurants such as found in Hong Kong. In the present study, the most commonly used cooking oil, peanut oil, was kept at 260°C in an environment typical of a commercial kitchen that consisted of a two-burner stir-frying cooking range, a single-tank electric fryer, a baffle-type grease extractor and an exhaust duct.
