SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet …

Mar 11, 2016· Does anyone know if there is a minimum flue velocity required by any standards for a chimney connected to a pellet stove. Following my calculation the velocity of the gas in this chimney is 0,49 m/s, that in my opinion is too low. Infact a low flow velocity will allow particles to settle out and promote condensation of any creosote that may form.
