Activated carbon powder controls flue gas emissions
15 Jan 2000
Keeping up with today's stringent emission controls presents a constant challenge to companies which have processes that produce toxic emissions.
Tyseley Waste Disposal has solved the problem by installing a FG3 Fluecarb powder activated carbon (PAC) system from Sutcliffe Speakman Carbons. Tyseley incinerates around 1,000 tonnes of Birmingham's waste a day, and uses the PAC to remove the majority of heavy metal and ceramic pollutants from issuing flue gases.
Tyseley burns the waste in two water-cooled combustion chambers. The resulting gas passes through a three-stage superheating steam system and is discharged to a flue gas cleaning plant in which acid gases, furans, and dioxins are removed.
The Fluecarb powder is injected by an atomiser as a carbon/water/ lime slurry droplet mix into the gas stream emanating from the municipal waste incinerator/boiler.
The slurry from the Fluecarb is sprayed into the flue gas as it enters the reactor chamber where it reacts with the gas constituents, neutralising the acid gas phase. Spent dried powder is captured in the filter bag house located down stream of the reactor.
