REGENERATIVE OXY-FUEL COMBUSTION SYSTEM AND METHOD

摘要

The present invention relates to a regenerative oxy-fuel combustion system and a combustion method using the same, more specifically, to a regenerative oxy-fuel combustion system comprising: a combustion chamber having one side and the other side on which combustion nozzles are respectively provided, the combustion nozzle having an oxygen injection part and a fuel injection part; heat storing chambers which are connected to each of the combustion nozzles, into which fuel gas generated in the combustion chamber is flowed during a heat storage mode such that heat is stored, and into which oxygen is flowed such that the inflow oxygen is preheated and then supplied to the oxygen injection part of the combustion chamber in a supply mode; a heat exchanger into which a part of the fuel gas generated in the combustion chamber is flowed such that fuel is preheated; and a bypass passage which is provided between the heat exchanger and the combustion chamber, and supplies a part of the fuel gas generated in the combustion chamber to the heat exchanger.
