Rural kitchens can be equipped with range hoods. Influenced by the structure of the kitchen, the diameter and position of the cooker, it is difficult for the kitchen with firewood stove to discharge oil smoke satisfactorily. Kitchen lampblack has two major components-burning lampblack and cooking lampblack; Influenced by knowledge and traditional habits, most people say that oil smoke and smoke exhaust refer to the latter. In fact, the former is equally harmful to indoor air and user health. At this point, the firewood stove has an inherent advantage, because its attached flue can discharge most of the combustion exhaust gas. This topic is mainly aimed at combustion waste gas, which has obvious seasonality. We can try to install a guide cover at the flue outlet (the picture is for reference only) to solve this problem. Judging from the emission of cooking oil fume, range hoods have inherent limitations on firewood stoves. From the day of its birth, the range hood in China has taken urban housing as its basic goal, and its length, width, height and even installation surface are all based on urban small kitchens and pots. Even the national standard of range hoods is formulated according to urban housing. The kitchen area of wood stove is large, the diameter of pot stove is large, and it is rarely against the wall. Using a range hood with a small smoke collection opening and attached to the wall, the oil fume emission effect will be very general; If you want to install it above the cooker, it will be difficult to repair. Therefore, it is a vacancy in the market to use a range hood suitable for large-caliber wood stoves far away from the wall, with the main purpose of discharging lampblack alone; It is unknown where the firewood stove will develop and whether there will be enterprises developing products in this field in the future.
