A proposal for SO sub(2) abatement in existing power plants using rich in calcium lignite

Under current European legislation for the abatement of SO[SUB 2] emissions and the strict ELV after 2016, existing power plants need to apply flue gas desulphurization technologies. For the majority of the units operating in Northern Greece and elsewhere in the Balkans, wet FGD is not the desired o...

Description
Summary:Under current European legislation for the abatement of SO[SUB 2] emissions and the strict ELV after 2016, existing power plants need to apply flue gas desulphurization technologies. For the majority of the units operating in Northern Greece and elsewhere in the Balkans, wet FGD is not the desired option due to the high capital investment involved and the limited service life of the units. A feasibility study carried out for a dry FGD installation is compared to wet FGD technology. It turns out that if lignite feed homogenization is employed, power plants can afford a compromising solution with power load losses in case of peak SO[sub 2] emissions and dry FGD installations instead of the classic and expensive wet FGD solution.
