Abstract: Method and installation (apparatus) for continuous combustion of combustibles effecting combustion in a closed room into which a controlled quantity of substantially pure oxygen is introduced. The gases emitted by the combustible combined with oxygen to produce a semi-continuous explosion as a first effect; also produce as a side effect, an atomization of any water present (in the form of steam) and of any gaseous combustion products within the closed room as a second effect. Energy is provided not only in the form of calorific energy from combustion, but is released as radiation, and other forms produced by the atomization of the water and gaseous combustion products, including the kinetic energy of the gaseous molecules within the closed room.
