Due to the nuclear nature of the transmutation of the two bodies, Firestorm is able to produce nuclear energy in the form of fire from parts of his body, specifically his head and hands as well as propel himself with the flames in to the sky. The Firestorm Matrix is possible to create with unwilling participants, but parts are normally mixed up, which causes a confused Firestorm, overloading the Matrix and causing the body to go nuclear, ultimately resulting in an explosion.
