Desulfurization Characteristics of Fuel-Born Alkali and

Feb 15, 2021 · Kideco and Bayan coals, which meet the design-coal standard of the boiler, have high inherent Ca/S ratios of 2.0–2.7 and (CaO equivalent) TA/S ratios of 3.5–3.9. The boiler was designed to operate with a Ca/S ratio of 3.4 to meet the SO 2 emission standard of 80 mL/Nm 3 (atmospheric emission allowance for coal-fired power plant boilers in
