PURE OXYGEN COMBUSTION TYPE VAPORIZING APPARATUS CAPABLE OF COLLECTING AND STORING CARBON DIOXIDE FROM EXHAUST GAS

摘要

PURPOSE: A pure oxygen combustion type vaporizing apparatus is provided to reduce the amount of carbon dioxide which is discharged from a liquefied natural gas (LNG) vaporizing unit by improving combustion efficiency of a burner.;CONSTITUTION: A pure oxygen combustion type vaporizing apparatus (1) comprises a liquefied natural gas (LNG) storage unit (100), an LNG vaporizing unit (200), an oxygen production unit (300), a carbon dioxide liquefying unit (400), and a liquefied carbon dioxide storage unit (500). The LNG vaporizing unit comprises a water tank (210); a burner (220) which is provided inside the water tank, and heats the water in the water tank by burning a fuel gas; and a first heat exchanger (230) which is provided inside the water tank, and which vaporizes the LNG that is supplied from the LNG storage unit, passes through the first heat exchanger, and exchanges heat with the water heated inside the water tank. The oxygen production unit produces oxygen, and supplies oxygen to the burner. The carbon dioxide liquefying unit gathers carbon dioxide from exhaust gas which is discharged from the LNG vaporizing unit, and liquefies the gathered carbon dioxide. The liquefied carbon dioxide storage unit stores the carbon dioxide which is liquefied by the carbon dioxide liquefying unit.;COPYRIGHT KIPO 2013
