boiler flue gas desulfurization method

Glossary of Mining Terms - Coal Education

Flue Gas Desulfurization – Any of several forms of chemical/physical processes that remove sulfur compounds formed during coal combustion. The devices, commonly called "scrubbers," combine the sulfur in gaseous emissions with another chemical medium to form inert "sludge" which must then be removed for disposal.

Fossil fuel power station - Wikipedia

Fossil-fuel power stations, particularly coal-fired plants, are a major source of industrial wastewater. Wastewater streams include flue-gas desulfurization, fly ash, bottom ash and flue gas mercury control. Plants with air pollution controls such as wet scrubbers typically transfer the captured pollutants to the wastewater stream.

Valmet CFB Boiler utilizes circulating fluidized bed

Valmet CFB Boiler (formerly known as CYMIC) is an advanced circulating fluidized bed (CFB) boiler developed by Valmet. It combines high-efficiency combustion of various solid fuels with low emissions, even when burning fuels with completely different calorific values at the same time.

Circulating fluidized bed - Wikipedia

The circulating fluidized bed (CFB) is a type of Fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion. while achieving lower emission of pollutants.Reports suggest that up to 95% of pollutants can be absorbed before being emitted into the atmosphere. The technology is limited in scale however, due to its extensive use of limestone, and the fact

Oxygen-blown coal gasification captures CO 2 from gas having a high CO 2 content of about 40% under pressure ranging from 2.5 megapascals to 3.0 megapascals (pre-operation CO 2 capture), so that the gas flow to be treated is lower than the CO 2 content to be captured (post-operation CO 2 capture) from the boiler exhaust gas.
