Abstract
The present invention discloses a system for reducing ammonium bisulfate blockage in air preheaters of coal-fired power plants, comprising at least one powder, at least one powder injection device, and at least one powder storage device; Under the action of power, the powder enters the powder injection device from the powder storage device, and is then sprayed into the flue between the SCR denitrification reactor and the air preheater. The powder can selectively adsorb the precursor ammonia gas and/or sulfur trioxide of ammonium bisulfate, thereby reducing the generation of ammonium bisulfate, removing the ammonium bisulfate that causes blockage of the air preheater from the source, and reducing the deposition of ammonium bisulfate and/or ash on the heating surface of the air preheater. It has the characteristics of simple process, low equipment cost, low price of powder used, and low construction and operation costs.
