<prompt> Translate the following text to EnglishKwa mfano, katika mifumo ya zamani ya FGD kwa vituo vya 2,600 MWh ilijumuisha absorbers sita, hata hivyo, leo mifumo hii ingekuwa uwezekano wa kubuni kwa mifumo ya absorbers nne, au takriban 650 MWh ya uwezo wa boiler kwa absorbers.  <response>: For example, in the past FGD systems for 2,600 MWe stations included six absorbers; however, today these systems would likely be designed for four absorber systems, or approximately 650 MWe of boiler capacity per absorber.
