Method for absorbing CO2 in the emission gas and recycling Calcium Carbonate by utilizing eluate of coal ash in the anthracite-fired fluidized-bed power plant.

摘要

PURPOSE: A carbon dioxide processing and calcium carbonate generation collecting method using calcined anthracite flowing-layer generating station fly ash is provided to reduce carbon dioxide by fixing with settling carbonate. CONSTITUTION: A carbon dioxide processing and calcium carbonate generation collecting method using calcined anthracite flowing-layer generating station fly ash comprises the following steps: inserting 1~3wt% of limestone to a puverizer on a coal combustion generating station, for dissolving fly ash, and using eluate to increase the content of alkali oxide; and maintaining the pH of 1.5~5 of a buffer for increasing the solubility of the alkali oxide, by inserting an additive.
