【Abstract】 Mainly researches the difference in the superheater and reheater of No.2 boiler in Pingwei Power Plant in Anhui, bring forward the project from flue gas side. With the reference of numerical simulation method and the premise of reserving the virtue of tangential firing, it advances that the burner jet is disposed in-whirl and de-whirl time and again to obtain and maintain the state of slender whirl which will make the boiler stable, and accordingly resolves the problem of heat difference.更多还原
