Flue Gas Desulfurization | Yokogawa Australia
Wet flue gas desulfurization or scrubber systems are an excellent way of reducing the sulfur dioxide emissions caused by coal combustion boilers. The flue gas discharged from the boiler is fed into the absorber. In the absorber, a mixture of water and pulverized limestone is sprayed on the flue gas. The limestone slurry absorbs the sulfur ...
