Russian soldiers on the Ukraine-Russia front showed a stunning scene of a T-80U tank starting up, with the engine exhaust port continuously spewing fire. However, this is probably not a malfunction, but rather because the T-80U tank uses a gas turbine engine. The combustion process of a gas turbine itself is intense, and if the high-temperature exhaust contains unburned fuel, it can cause secondary combustion at the exhaust port or when encountering external oxygen. Alternatively, when the engine's fuel is not properly atomized, the unburned hydrocarbons in the high-temperature exhaust can form flames upon contact with sufficient oxygen.
