Abstract
The invention discloses a settled ash conveying system and method. According to the settled ash conveying system and method, fly ash generated after combustion of a boiler reaches an economizer alongwith the flowing direction of smoke and is separated in a settled ash hopper, an inlet closing door is arranged at an inlet of a settled ash bin, and when equipment goes wrong and needs to be overhauled, related equipment can be isolated, so that overhauling is facilitated. The height of the settled ash hopper in the vertical direction is far larger than the height of the joint of the system and adry slag machine and the height of the joint of the system and a dry slag machine steel belt, and the purpose of ash conveying can be achieved through the gravity of settled ash. The dry slag machineand the dry slag machine steel belt communicate with a boiler cold ash hopper, negative pressure exists at the position, the suction effect on the settled ash falling to the position can be achieved,and the fluidity of the settled ash is enhanced. According to the boiler load and the coal ash content condition, part of the system is selectively isolated through the inlet closing door, and the operation mode is flexible and changeable.
