Spray dryer/baghouse flue gas desulfurization (FGD) evaluation for high-sulfur utility applications

Conference ·
OSTI ID:6338653

The Tennessee Valley Authority (TVA) initiated a program in 1983 to evaluate two pilot spray dryer/baghouse FGD systems. The main objective of this testing was to determine if the new type of FGD system, which was being commercialized on low-sulfur coal applications, was capable of treating flue gas from high-sulfur coal-fired utility boilers. Variables which were evaluated include lime stoichiometry, approach-to-saturation temperature, recycle rate, flue gas residence time in the spray dryer, atomizer speed, inlet flue gas temperature, and inlet SO/sub 2/ concentration. As expected, the SO/sub 2/ removal efficiency is a strong function of lime stoichiometry and approach-to-saturation temperature.
