<p>PURPOSE:To prevent an aggregation and a choking of a reactant powder by cooling the powder carried from a storage tank by air and then returning the powder to the storage tank after separating the powder from the air, while feeding the powder into a flue gas at a constant rate. CONSTITUTION:A cold air is drawn into a storage tank 10 and carries powder to a cooling and separation equipment 16, wherein the powder is cooled and separated from the air, and the cooled powder is returned to the storage tank 10 through a piping 17. The powder in the storage tank 10 is taken out at a constant rate by a constant rate feeder 12 and fed into a combustion flue gas after cooled in a cooler 13 by a carrier air and a compressed air. This powder is collected as a reactant and fly ash by a dust collector 1, and recycled to the storage tank 10 and reused.</p> |
