Description

Technical Field

[0001] The utility model relates to the technical field of material adding equipment, in particular to a boiler additive adding device for improving combustion efficiency. Background Art

[0002] Sodium in coal is an important factor causing fouling of heat transfer surfaces during the boiler combustion process of coal. Therefore, the combustion and utilization of high-sodium coal are greatly restricted. In order to improve the utilization rate and combustion efficiency of coal, various additives need to be added. Before feeding, the additives need to be crushed and mixed, and then transported to the coal bunker, and then mixed with coal again to make the coal burn more fully during the combustion process.

[0003] The patent with the publication number CN212481358U and the name of a coal additive feeding device for an environment-friendly coal-fired boiler discloses a coal additive feeding device for an environment-friendly coal-fired boiler, including a working box. An input port and an output port are respectively opened on the upper surface and the lower surface of the working box. Four corners of the upper surface of the working box are fixedly connected with auxiliary plates. An auxiliary shaft is fixedly connected between two groups of the auxiliary plates on the left side of the working box and between two groups of the auxiliary plates on the right side of the working box. For this coal additive feeding device of the environment-friendly coal-fired boiler, through the cooperative action of the feeding plate, the hydraulic cylinder, the auxiliary block, the auxiliary plate, the auxiliary shaft, the smooth shaft, the connecting plate and the working box, it can be convenient for workers to add coal additives and coal, and at the same time, the coal additives and coal can be mixed to a certain extent. However, this patented technology has deficiencies in the actual application process. This device needs to first take out the mixed coal and then re-add it to the boiler, which is more troublesome in operation and consumes more physical strength of workers. This device does not perform preliminary treatment on the additives. If the additives are agglomerated due to reasons such as humid weather, they cannot completely adhere to the coal, resulting in insufficient mixing of the coal and the additives.
