GE’s Steam Power Systems wet flue gas desulfurization (WFGD) portfolio consists of the following options: WFGD-Open Spray Tower (OST). The WFGD-OST advanced design offers lower power consumption and has smaller dimensions compared to previous versions, while reaching very low emissions. The gypsum by-product recovered is usable as wallboard and is of cement quality. Flowpac WFGD. The Flowpac WFGD contains a turbulent bed absorber, in which a flue gas passes through limestone slurry. It is targeted for applications requiring increased SO2 removal efficiency and enhanced SO3 removal efficiency. For power generation, it is designed for unit sizes up to 360 MW with varying fuel conditions, such as sulfur content, which can rise to high level.
More than 75 GW installed or in design for power generation, and numerous industrial applications (iron, steel, petrochemical, or pulp and paper).
Flexible absorber performance with excellent controllability of the SO2 removal rate.
Improved performance control through patented sulfite analyzer.
Fuel flexibility for all types of fuel (including heavy fuel oil) with sulfur content up to 4.5% for WFGD-OST. and up to 6% for Flowpac WFGD.
Lower power consumption with lower emissions of particulates and aerosols.
Sea Water FGD (SWFGD) Technology
The Steam Power Systems SWFGD is a unique no-by-product SO2 removal solution. Thanks to more than 40 years of experience in SWFGD for power generation and industry applications, GE is one of the world’s leading providers with the biggest SWFGD installed fleet. The GE design features a proven packed tower approach to enhance performance and absorber sizing.
