What is the central temperature of the cigarette end? What is the central temperature of the cigaret

The central temperature of cigarette butts is 700 ℃ ~ 800 ℃, the surface temperature of cigarette butts is about 250 ℃, and the temperature of sparks ejected from cigarette butts is about 200 ℃.

After the cigarette butts are discarded, the external temperature is 550 ℃ - 600 ℃ and the central temperature is about 830 ℃ in the state of spontaneous combustion. This temperature is significantly higher than the ignition point of many other combustibles. After the remaining cigarette butts are discarded, they can continue to burn for one to four minutes, which is easy to cause a fire in case of combustibles.

Smokers should have public morality and a certain awareness of fire prevention. After smoking, cigarette butts should be completely extinguished. After being extinguished, they should be placed in ashtrays, metal, glass and other non flammable appliances. They should not throw them around at will, let alone smoke in non-smoking places.
