PURPOSE: To finely divide carbon residue and ash with reduction of sulfur content by inserting a magnetic material into a household can, and to eliminate malodor by means of complete combustion in a kerosene stove.

CONSTITUTION: By inserting a cassette-type magnetic material 5 of thickness 10W 15mm into household kerosene can 1 and bringing the magnetic material into contact with the kerosene, a hydrocarbon nucleus forming sludge in the kerosene is destroyed, forming a dispersed minute material, and connection between metal particle molecules is broken, forming finely divided particles.

EFFECT: Viscosity and surface tension of the kerosene are lowered, and the wick of the stove is prevented from deposition of carbon residue or ash, which effects complete combustion.
