The Calcination Process in a System for Washing

industry standard.5,11 The washing process of the WCCB system was studied, and the influence of different alkaline reagents (e.g., calcium hydroxide [Ca(OH) 2] and sodium bicarbonate [NaHCO 3]) used for acid gas removal in MSWI air pollution control systems on the washing process was examined. It was found that fly ash collected by a bag filter

The Calcination Process in a System for Washing

This research presents the reduction of chlorine and washing of three kinds of fly ash (RFA, CaFA and NaFA) during the calcination process. By comparing the results of those fly ashes, it is shown that NaHCO 3 is better than Ca(OH) 2 as a neutralization reagent to treat exhaust gas from an

Calcination - Wikipedia

In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g) The standard Gibbs free energy of reaction is approximated as ΔG° r = 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C.
