REHEAT BOILER AND GAS TEMPERATURE CONTROL METHOD OF REHEAT BOILER

摘要

reheat boiler according to the present invention combustion gas is generated by the combustion of the burner , the furnace 102 from a superheater , a main boiler configured to flow through the evaporation Tube Bundle , and reheating to 108 having a reheat burner 107 in the wake side of the Tube Bundle evaporated , re- opening the upper side of the reheat to 108 (109 ), with a reheat boiler having , in the as 108 has a reheat reheat burner 107 and the combustion air supply section for a portion of the air for combustion in a position opposed to an air supply (11b) for combustion (12) . By counter collision of the combustion gas (107a) and the combustion air (11b), promote the mixing of air (11b) with the combustion of the combustion gas (107a) and , by changing the flow pattern of the combustion gas , reheat to 108 the imbalance of reducing the temperature of the combustion gases (107a) at the exit . ;
