PURPOSE: A fog removing system is provided to prevent delay of taking-off and landing of an airplane, accidents and loss by obtaining the visual field with eliminating fog from the freeway, the runway or the harbor. CONSTITUTION: A fog removing system comprises compression low-temperature tanks(1,2) storing at low temperature by compressing nitrogen liquid and liquid oxygen on the ground or underground at the runway; an expansion valve(3) adjusting nitrogen and oxygen from the compression tanks to the volume ratio of nitrogen of 79% and oxygen of 21%; an evaporator(4) separating moisture from fog by evaporating liquid from the expansion valves; a heater(5) heating nitrogen and oxygen gas from the evaporator; and a nozzle(6) eliminating fog by lowering the humidity to 70/80% with injecting mixed air of nitrogen and oxygen. Accidents and loss are prevented by eliminating fog in the freeway, the runway or the harbor.
