Fire extinguishing steam control method, apparatus and device of medium speed mill and storage medium

Abstract

The invention discloses a fire extinguishing steam control method, apparatus and device of a medium speed mill and a storage medium. The method includes the steps of acquiring raw coal volatile matterin the medium speed mill, a coal stop signal of a coal feeder connected with the medium speed mill and an outlet temperature parameter of the medium speed mill at the current moment; judging whetheran operation state, corresponding to the medium speed mill, of the raw coal volatile matter meets a first opening condition of a fire extinguishing steam electric door, whether the coal stop signal meets a second opening condition of the fire extinguishing steam electric door, and whether the outlet temperature parameter meets a third opening condition of the fire extinguishing steam electric door; and if at least one of the first opening condition, the second opening condition and the third opening condition is met, controlling the fire extinguishing steam electric door to open. The technicalproblem that fire extinguishing steam of an existing medium speed mill is manually input by operation staff, and consequently the fire extinguishing steam can hardly effectively interfere in time, and finally skip milling or damage of the medium speed mill is caused is solved.

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...
