How many degrees can the center temperature of cigarette butts reach?

The center temperature of cigarette butts is between 700℃ and 800℃.

The surface temperature of cigarette butts is 200℃ ~ 300℃, and the center temperature of cigarette butts can reach 700℃~800℃. When smoking, oxygen is connected with fire, and the temperature of cigarette butts will be relatively high, basically reaching 800 degrees Celsius, while when not smoking, the temperature will drop, generally staying at around 700 degrees Celsius.

The flame on the cigarette butt is an open flame, and its flame is obvious. When burning, the surface temperature is between 200 degrees Celsius and 300 degrees Celsius. Usually, the ignition point of combustible materials is lower than it, but cigarette butts burn all the time, so the temperature will be higher.

When smoking, we'd better not throw the remaining cigarette butts about, but put them out in the ashtray. If we throw them around, we will encounter some substances that are easy to ignite, which is likely to cause fires and threaten our lives.
