Fire extinguishing steam control method, device, equipment and storage medium for medium-speed coal pulverizer

Abstract

The present application discloses a fire extinguishing steam control method, device, equipment and storage medium of a medium-speed coal mill, wherein the method includes: obtaining the raw coal volatile matter in the medium-speed coal mill and the The coal cut-off signal of the connected coal feeder and the outlet temperature parameters of the medium-speed coal mill; determine whether the operating state of the medium-speed coal mill corresponding to the volatile content of raw coal meets the first opening condition of the fire extinguishing steam electric door, and whether the coal cut-off signal meets the Whether the second opening condition of the fire extinguishing steam electric door and the outlet temperature parameter meet the third opening condition of the fire extinguishing steam electric door; if at least one of the first opening condition, the second opening condition, and the third opening condition is satisfied, then control the fire extinguishing steam The electric door is opened, which solves the technical problem that the fire extinguishing steam of the existing medium-speed coal mill is manually input by the operator, which makes it difficult to intervene in a timely and effective manner, and eventually causes the medium-speed coal mill to skip grinding or equipment damage.

Description

technical field [0001] The present application relates to the technical field of coal pulverizer control, in particular to a method, device, equipment and storage medium for controlling fire extinguishing steam of a medium-speed coal pulverizer. Background technique [0002] Thermal power generation is the main force in the development of electric power in modern society, and still occupies most of the electric power market. Therefore, ensuring the safe operation of thermal power plants is crucial to maintaining power stability. The medium-speed coal mill is an important component of a thermal power plant. However, during the operation of the medium-speed coal mill, spontaneous combustion or deflagration accidents may occur, which will further cause skipping or damage to the coal mill equipment. Therefore, the medium-speed coal mill Opportunity to set fire extinguishing steam for intervention and treatment of spontaneous combustion of pulverized coal in the coal mill. [0...
