the purpose of adding ammonia in boiler flue gas

Gas-phase oxidation followed by reaction with ammonia. 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 . Get a ...

Simultaneous desulfurization and denitrification of flue ...

Sep 01 2020 · A process of simultaneous desulfurization and denitrification of flue gas was conducted in this study. The flue gas containing 200 mg·m 3 NO 10004000 mg·m 3 SO 2 3%9% O 2 and 10%20% CO 2 was first oxidized by O 3 and then absorbed by ammonia in a bubbling reactor. Increasing the ammonia concentration or the SO 2 content in flue gas can promote the absorption of NO X and ...

Flue Gas Desulfurization (FGD) Wastewater Treatment

Flue Gas Desulfurization (FGD) Wastewater Treatment. Flue gas treatment contains different methods and scrubbing processes. Commonly used wet scrubber systems generates wastewater which contains high concentrations of ions with scaling potential heavy metals TSS and ammonia. This waste water stream needs to be treated before disposal and may even be re-used as process water.

Ammonia-based FGD

Efficient ammonia desulfurization (EADS) is the core service of JET. From the reaction between NH 3 and SO 2 it is capable of efficiently removing SO 2 from the exhaust gas and also producing valuable fertilizer ammonium sulfate. Compared to the most widely used limestone-gypsum process in boiler flue gas treatment the EADS is more efficient consumes less power and produces no waste water or solids.
