Wet flue gas desulfurization or scrubber systems are very effective in reducing sulfur dioxide (SO2) emissions caused by coal combustion boilers. The flue gas discharged from the boiler is fed into the absorber, where a mixture of water and pulverized limestone is sprayed on the flue gas. The limestone slurry reduces sulfur emissions by absorbing the …
Wet flue gas desulfurization (WFGD) system is the core equipment for removing SO 2 from coal-fired power plants, and it also has an important synergistic effect on the removal of selenium. However, the removal efficiency of Se across WFGD systems is not as expected, and it varies greatly in different coal-fired units (12.5-96%).
The slurry jet technique is widely used for flue gas desulfurization, whereas the increase in its absorption efficiency is required to meet the increasingly strict exhaust emission standards.
