A metallic fuel mixture including solidic powders such as silicon, aluminum and magnesium together with an oxidant, and steam and hydrogen are fed into a combustor to undergo combustion therein. The combustor is positioned within a steam chamber enclosure filled with water as working fluid which is heated by the combustion.
