Charcoal barbecue pits use charcoal as fuel.
Gas barbecue ovens generally use gas as fuel.
Electric barbecue, using electric heat to directly act on food.
Butane barbecue oven uses canned compressed butane gas as fuel and uses open flame for barbecue (as shown above). Butane gas will produce carbon dioxide and water vapor when burning, but if oxygen supply is insufficient, it will produce carbon and carbon monoxide, which will lead to human poisoning and even death (carbon monoxide poisoning), which can be considered harmless to a certain extent. Butane barbecue oven has the advantages of faster barbecue speed, but the disadvantages are that it is not suitable for indoor use (carbon monoxide is easy to be produced in a poorly ventilated environment), open flame is dangerous, and the cost of using compressed canned flammable materials is high. Ordinary users are not recommended to barbecue, only suitable for professional barbecue.
Charcoal barbecue is a kind of barbecue oven which uses the heat energy generated by charcoal combustion. It has been used by human beings for a long time. Carbon dioxide will be produced after charcoal burning, but if oxygen supply is insufficient, carbon monoxide will be produced, which will lead to human poisoning and even death (the same as butane barbecue oven). When charcoal is burned, a large amount of soot harmful to human body will be produced due to high temperature, especially when oil drops on high temperature charcoal, which will produce carcinogens, and flying carbon ash will fly into food and be ingested by human body (as shown in the above picture). The advantages of charcoal barbecue are outdoor application (while avoiding carbon monoxide poisoning) and faster barbecue speed (slower than butane and slightly faster than electricity). Disadvantages are that naked fire is more dangerous, with carcinogen risk and higher cost (cheaper than butane and more expensive than electricity), which is more suitable for outdoor barbecue. When choosing a carbon barbecue oven, choose a smokeless style, which can minimize the harm to health.
As a new product, electric barbecue has been accepted by consumers. It uses electric energy to directly act on food, and electric heating, as a clean energy source, can be used as long as there is electricity, which is convenient and fast. The advantages of electric barbecue are indoor use, cleanliness, no oil smoke, low cost, high efficiency, convenient use, health and harmlessness. The disadvantage is that it is not suitable for outdoor use (outdoor power supply is a big problem). When purchasing electric barbecue, you should buy products from big manufacturers, and the quality is relatively guaranteed. In addition, you should choose an electric barbecue oven with DuPont non-stick baking tray, which will bring great convenience for both use and cleaning.
