[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy from the fuel and electrical energy, and the boiler outputs a certain amount of thermal energy in the form of steam, high-temperature water, or an organic heat carrier. During operation, the boiler produces a large amount of flue gas and residue from the combustion products within the boiler. Therefore, a flue gas dust removal device is required to treat these flue gases and residue.
