The invention discloses a flue module for a boiler system and the boiler system with the flue module. The flue module for the boiler system comprises a first flue extending in an up-down direction, asecond flue extending in a first horizontal direction and connected with the lower end of the first flue through a first end, an ash hopper arranged on a base plate of the second flue and with an accommodating cavity, a separation plate arranged in the accommodating cavity and a baffle plate arranged on the separation plate, wherein a collecting cavity is defined between the separation plate and the wall surface of the accommodating cavity; the separation plate is provided with a smoke inlet and a smoke outlet; every one of the smoke inlet and the smoke outlet communicates with the collectingcavity; the smoke outlet is positioned above the smoke inlet; and the baffle plate is arranged on the separation plate, extends from the separation plate to a direction far from the collecting cavity,is positioned above the smoke inlet, and cooperates with the smoke inlet. The flue module for the boiler system can effectively remove soot particles in smoke, in particular soot particles with millimeter particle sizes.
Description
technical field [0001] The invention relates to the field of energy, in particular to a flue assembly for a boiler system, and also to a boiler system with the flue assembly. Background technique [0002] There is fly ash in the flue gas produced by coal combustion in the boiler, which will cause blockage, wear and catalyst poisoning of the SCR catalyst bed, thereby affecting the performance and service life of the SCR catalyst. Contents of the invention [0003] The purpose of the present invention is to overcome the problems existing in the prior art, to provide a flue assembly for a boiler system and a boiler system with the flue assembly, the flue assembly for a boiler system can effectively remove the Fly ash particles with millimeter particle size. [0004] In order to achieve the above object, the first aspect of the present invention provides a flue assembly for a boiler system, the flue assembly for a boiler system includes: a first flue extending in an up-down d...
