Embodiment Construction

[0023] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0024] An aspect of an embodiment of the invention provides a method for controlling a pulverizing system. figure 1 It is a flowchart of a method for controlling a pulverizing system provided by an embodiment of the present invention. like figure 1 As shown, the method includes the following steps.

[0025] In step S10, it is judged whether the first preset condition for starting the pulverizing system is met, and if the first preset condition is met, step S11 is executed, otherwise, the process ends. The first preset condition is: the coal mill startup check card is completed,...

Abstract

The embodiment of the invention provides a method and device for controlling a powder making system, and belongs to the field of power generation. The method comprises the step of judging whether thefirst preset condition for starting the powder making system is met, and under the condition of meeting the first preset condition, if a coal mill is not started, carrying out control to finish the first preset operation so as to finish starting of the powder making system; coal mill lubrication station electric heating interlocking input, coal mill lubrication pump starting, coal mill steam fireextinguishing electric door opening, coal mill seal wind electric door opening, coal feeder coal feeding amount automatic input, coal mill cold wind adjusting door automatic inputting, coal mill hot wind adjusting door automatic inputting, coal mill opening hot wind door shutting, coal mill opening cold wind door shutting, coal mill outlet door opening, circumference wind baffle automatic inputting, auxiliary wind baffle automatic inputting, coal feeder outlet gate plate door opening, coal feeder inlet gate plate door opening, coal mill starting, coal feeder starting, lubricating oil pump interlocking inputting and seal draught fan interlocking inputting. The powder making system can be started through one-key control.

Description

technical field [0001] The invention relates to the field of power generation, in particular to a method and device for controlling a pulverizing system. Background technique [0002] The original start-stop sequence control logic of the pulverizing system is relatively simple. It is only for the sequence control logic designed between the hot air isolation door, the exit quick-closing door, the coal mill and the coal feeder, and the control of the oil station and auxiliary systems still needs to be operated. Manual operation by personnel. Only when the pulverizing system starts normally and the pulverizing system is merged into other coal mills, can the cold air, hot air and coal feeder be automatically put into operation, so that the pulverizing system can participate in automatic adjustment. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a method and device for controlling a pulverizing system, which can realize...
