(PDF) Costs and Benefits of Installing Flue

This paper examines the costs and benefits of retrofitting coal-fired power plants in India with flue-gas desulfurization units (FGDs or scrubbers) to reduce SO 2 . 2 Although Indian coal has low-sulfur content, meeting new emission stan- dards will require retrofitting most coal-fired power plants with FGDs (Cropper et al., 2017).

Life Cycle Assessment of Coal

31-5-2001The Average coal power plant consists of the following main equipment/process steps: pulverized coal boiler, baghouse filter, conventional limestone flue gas clean-up (FGC) system, heat recovery steam generator, and steam turbine (see Figure 4).
