Coal blending combustion method, device and equipment and computer readable storage medium

Abstract

The invention discloses a coal blending combustion method, device and equipment and a medium. The method comprises the steps that a relation model of coal quality information and combustion state datais trained through historical coal quality information and historical combustion state data; setting a plurality of different coal blending proportions according to the real-time coal piling information at the current moment, and calculating corresponding target coal quality information according to the coal quality parameters of different coal types; inputting the target coal quality informationinto a relation model to determine corresponding target combustion state data; respectively updating the real-time coal piling information by utilizing the blending proportion of each coal type, andcontinuously setting the blending proportion of the coal types for cyclic calculation; and when the circulation condition meets a preset condition, determining an actual coal blending proportion corresponding to each stage in the coal blending combustion process according to each target combustion state data in the circulation process. According to the method, the coal blending combustion efficiency can be improved, and the operation cost is reduced.

Description

technical field [0001] The invention relates to the field of industrial coal yards, in particular to a coal blending and blending burning method, device, equipment and computer-readable storage medium. Background technique [0002] At present, the coal yard management system of power generation enterprises at home and abroad has been widely used in coal yards of thermal power plants, and with the rapid development of automation equipment, advanced measurement technology, and computer technology, coal yard management has gradually realized digitization and informationization, which provides a basis for transshipment strategies. Optimization, on-site equipment control, intelligent coal blending, etc. provide information resources, so that the coal yard management is more scientific and standardized, efficient and energy-saving. Among them, coal blending and blending is an important way for thermal power plants to reduce power generation costs. In the coal blending and blending...

Problems solved by technology

However, in the case of complex and changeable coal types, on the one hand, the methods of the prior art may not be able to adapt to the actual production conditions of the coal yard of the thermal power plant, and cannot carry out coal blending and blending according to the determined coal blending ratio, reducing the coal blending rate. The efficiency of co-firing, on the other hand, may not be able to effectively utilize multiple coals, resulting in high operating costs
