Summary of the Invention 

The invention provides a method for evaporating liquefied gases, wherein liquefied gases in the storage (1) intensively absorb heat from the surroundings by sucking and ejecting (2, 8) the liquefied gases to the inner surface of the storage wall portion (dry wall) above the interface of the liquefied gas in the storage so that the liquefied gases flow onto the inner surface of the dry wall and stir the layer of the liquefied gases in the storage. Thus, the liquefied gases are facilitated and intensively absorbed heat from surroundings for evaporating. The invention also provides a system for evaporating the liquefied gases applying the above-mentioned evaporating method. Therefore, it is possible to salvage limitless, costless, heat source from the surroundings for evaporating the liquefied gases. Furthermore, the phenomenon of water accumulating the outside storage walls causing rust and oxidation is also reduced.

The first objective of the invention is to provide a method for evaporating liquefied gases so as to increase the thermal absorbability of the liquefied gases via the storage wall by increasing the thermal transferability from the surroundings to the liquefied gases through the dry wall, by stiring the liquefied gases in the storage for facilitating improved evaporation of the liquefied gas.

The second objective of the invention is to provide a system for evaporating the liquefied gases employing the above-mentioned method. The system needs to have a simple, inexpensive and easy-to-install structure.

The third objective of the invention is to apply the existent pressure of the liquefied gases in the storage as an energy source for driving the evaporating system and the like.

The fourth objective of the invention is to use heat from waste hot water and furnace smoke for evaporating the liquefied gases.

Technical field of the invention 

The invention relates to a method for evaporating liquefied gases for industrial purposes, wherein the liquefied gases are evaporated by absoring heat from the surroundings. The invention also provides a system for evaporating the liquefied gases according to the above-mentioned method.
