To convert the current potential combustion to coulomb oxidation while attaining energy saving and reduction in carbon dioxide by naturally burn dense carbon.

This device is a furnace adapted to input dense carbon coke from an upper opening port, promotes oxidation combustion by branching functions to the upper part and lower part within the furnace, and induces a coulomb energy that is a heat source such as light, magnetic wave, electricity, or radiation from a diffuse combustion potential by an oxidation reaction to generate a fourth-dimensional space energy with static pressure mainly composed of far infrared ray. The fusion heat by combustion of the carbon atom is stored in a dense carbon oxidizing element that is a refractory of alumina arranged on the circumference, and the radiant heat is amplified and reflected to increase the entropy of photons to form neutrons by flicking electrons of an atomic nucleus, and create a nuclear force energy by exciting nuclear vibration. The resulting photothermal source is guided to the upper stage and converted to pure and clean hot infrared ray again by an atomic fusing reaction element, and taken as a plasm arc.
