INTELLIGENT SOOT BLOWING CONTROL METHOD BASED ON MULTI-DIMENSIONAL EVALUATION FACTORS, AND SYSTEM AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/279601
Kind Code:
A1
Abstract:
An intelligent soot blowing control method based on multi-dimensional evaluation factors, and a system and a storage medium. The method comprises: selecting a plurality of boiler operation parameters which reflect the contamination degree of a heating surface corresponding to a soot blower and reflect the effect of soot blowing on the safety and economical performance of boiler operation, and using the boiler operation parameters as evaluation factors for selecting the soot blower; respectively performing priority level grouping on each evaluation factor according to the magnitude of the effect of each evaluation factor on boiler safety and on the degree to which operation is economical, and according to the level of the degree of association between each evaluation factor and the contamination of the heating surface; and determining whether the value of each evaluation factor is within a normal state range, counting the number of evaluation factors which are within each group of priority levels and the values of which are not within the normal state range, and according to the number of evaluation factors which are within each group of priority levels and the values of which are not within the normal state range, determining whether the soot blower is required to perform soot blowing. Therefore, the loss of soot blowing steam in a power plant is reduced, and the risk of blowing loss of a heating surface is reduced, thereby improving the safety and economical performance of boiler operation.
