    A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

  • Flue Gas Desulfurization

    Typical SO 2 removal processes are wet scrubbing and dry scrubbing. In wet scrubbing systems, the ones mostly used, the fly ash is removed first by an electrostatic precipitator (ESP), then the flue gas passes into the SO 2 absorber. Electrostatic precipitator performance is often enhanced by adding ammonia to the flue gas.
