In the work mechanisms for heating of heat educing compositions in an electric discharge channel are studied. The heat educing compositions are explosives filled with water that under atmospheric pressure can burn down only in the flame of an outside source as the water boils out. It is shown that well developed turbulent and radiant heat exchange has to be provided for effective proceeding of exothermal reaction in the electric discharge zone. The pressure exceeding 103 Pa and temperature corresponding to the onset of the active reaction must be achieved by the electrical discharge. The heat exchanging compositions must have heat containment which exceeds 3000 Jkg-1 and conductivity not less than 1 Ohm-1m-1.
