Abstract:

In tangential combustion system, the reheat steam temperature can be adjusted by changing burner nozzle angle to just the flame position. Adopting tilting burner is also an important way to adjust furnace outlet flue gas temperature. The significance of function recovery for tilting burner, effect factor, transformation situation were illustrated, energy saving benefit was analyzed, and the effect of adopting reheater reducing temperature water to system efficiency was discussed. It is important to know temperature adjusting characters of tiling burner, which would affect boiler safe and steady operation.

Key words: power plant boiler, tilting burner, function recovery, reheat steam temperature, adjustment characteristic
