🛡️ In-Situ DeSOx (Limestone CaCO3 to CaO, Molar Ratio Ca/S 2.0-2.5, 95% SO2 Capture)

FBC Limestone In-Situ Desulfurization Calculator

Size limestone ($CaCO_3$) injection systems for in-situ sulfur dioxide capture ($CaCO_3 ightarrow CaO + CO_2$, then $CaO + SO_2 + rac{1}{2}O_2 ightarrow CaSO_4$) inside fluidized bed combustion boilers: calculate molar Calcium-to-Sulfur Ratio ($Ca/S = 2.0 ext{ to }2.5$), achieve $>95%$ SO2 capture without external wet scrubbers, and clean air compliance yields.
