【Abstract】 In the paper the problem of overtemperature in the convective superheater of the boiler type HG- 670/140-9 is investigated comprehensively.By using the three-dimensional method,the fields of tem- perature and the velocity are calculated numerically.The reason of overtemperature is found,and some proposales are also put forward.The conclosions can be references for considering the boilers of the same kend.更多还原
