intimate contact with the flue gas to optimize absorption efficiency and drying in the spray chamber. For large utility boiler applications (illus-trated here), flue gas enters the spray dry absorber at two locations: the roof gas disperser and the central gas disperser. Smaller, lower gas flow installations require only a roof gas disperser.
Chat OnlineCombustion Efficiency. The combustion efficiency of a boiler is the indication of burners ability to burn fuel. The two parameters which determine the burner efficiency are unburnt fuel quantities in exhaust and excess oxygen levels in the exhaust. As the amount of excess air is increased, the quantity of unburnt fuel in the exhaust decreases.
