Bagasse fired boilers (Paper & Discussion) : Proceedings

The importance of fuel firing equipment cannot be over emphasized. The majority of boiler explosions occur in one of two ways: a failure of a boiler pressure part, or a furnace explosion. Jurisdictions and insurance companies have long recognized the need for the proper installation, maintenance, repair, operation and inspection of this equipment.

Flue-gas desulfurization - Wikipedia

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 scrubbing with a Ca(OH) 2 (hydrated lime

Experimental Investigation of Oxy-coal Combustion in a 15

Dec 14, 2018 · Pressurized oxy-coal combustion is considered as a promising carbon capture technology as a result of its potential of high efficiency and low cost in CO2 capture. However, experimental investigations of oxy-coal combustion under pressurized conditions are far less common than those under atmospheric pressure conditions, and hence, further research is needed to elucidate the effects …
