Abstract

The invention discloses a coal conveying partition. The coal conveying partition comprises a partition, and rotary blades rotationally arranged on the partition. The coal conveying partition disclosed by the invention is simple in structure, and enables pulverized coal to be uniformly spread on the horizontal coal conveying partition; and a pulverized coal mixer adopting the coal conveying partition enables the pulverized coal to be uniformly spread on the horizontal coal conveying partition, and blows the pulverized coal in a combustion chamber under the effect of primary air, and therefore fuel waste is reduced. The invention further provides a control method of the pulverized coal mixer. Rotational speeds of the rotary blades on the coal conveying partition are accurately controlled on the basis of PID fuzzy control, so that fuel utilization rate and boiler efficiency are further increased.

Description

technical field [0001] The invention relates to a baffle and a mixer, more particularly, the invention relates to a coal conveying baffle, a pulverized coal mixer and a control method thereof. Background technique [0002] At present, most of the boilers in power plants adopt the pulverization system in the intermediate storage room. The pulverized coal mixer is a device used to mix pulverized coal and the air required for combustion. [0003] However, the pulverized coal falling through the powder lowering pipe will accumulate in the middle of the horizontal partition, and the pulverized coal cannot reach both sides of the horizontal partition, which will make the pulverized coal unable to be fully and effectively used and waste fuel. The primary wind cannot completely blow the pulverized coal into the combustion chamber, reducing fuel utilization and boiler efficiency. Contents of the invention [0004] In order to solve the technical problem of fuel accumulation, the ...
