OXY-COMBUSTION SYSTEM USING CHEMICAL HEAT RECOVERY

摘要

PURPOSE: An oxy-combustion system using a chemical heat recovery method is provided to improve combustion efficiency of oxygen by preheating the oxygen provided to the combustion device using the heat generated by the reaction between carbon dioxide and calcium oxide. CONSTITUTION: An oxy-combustion system using a chemical heat recovery method comprises a pre-heater. The pre-heater preheats the oxygen provided to a lower oxygen combustion chamber(11) of a combustion device. The calcium oxide, saved in the pre-heater, generates heat by the reaction of carbon dioxide. The calcium carbonate absorbing heat is provided to the fuel combustion chamber in order to prevent the overheating of the upper part of a fuel combustion chamber(12).
