Embodiment 1

[0015] like figure 1 As shown, Embodiment 1 of the present invention provides a coal blending and blending optimization method, comprising the following steps:

[0016] S1. Collect the volatile matter and sulfur content of different types of coal, and establish a coal blending database;

[0017] S2. According to the order of sulfur content from high to low, different types of stock coal are divided into several subsets corresponding to the number of burner layers. The stock coal with high sulfur content corresponds to the burner of the high layer. Low inventory coal corresponds to low-level burners;

[0018] S3. According to the stock coal included in each subset, establish a coal blending volatile function of the corresponding burner;

[0019] S4. Taking the volatile content function of the coal blending as an objective function and taking the inventory of coal as a constraint condition, calculate an optimal coal blending and burning scheme for the corresponding burner.

Embodiment 2

[0056] Embodiment 2 of the present invention provides a coal blending and blending optimization device, including a processor and a memory, and a computer program is stored in the memory. When the computer program is executed by the processor, the coal blending provided by the above embodiment is realized. Blending optimization method.

[0057] The coal blending and blending firing optimization device provided in this embodiment is used to realize the coal blending and blending firing optimization method. Therefore, the technical effects of the coal blending and blending firing optimization method are also provided by the coal blending and blending firing optimization device, which will not be repeated here.

Embodiment 3

[0059] Embodiment 3 of the present invention provides a computer storage medium on which a computer program is stored. When the computer program is executed by a processor, the method for optimizing coal blending and blending combustion provided by the above embodiment is realized.

[0060] The computer storage medium provided in this embodiment is used to implement the coal blending and blending firing optimization method, so the technical effects of the coal blending and blending firing optimization method are also provided by the computer storage medium, and will not be repeated here.

Abstract

The invention relates to the technical field of coal blending combustion, and discloses a coal blending combustion optimization method and device and a computer storage medium, and the method comprises the following steps: collecting volatile components and sulfur contents of different types of coal, and building a coal blending database; according to the sequence from high sulfur content to low sulfur content, dividing different types of stock coal into several subsets in one-to-one correspondence with the number of layers of the burners, enabling the stock coal with high sulfur content to correspond to the burners at a high layer, and enabling the stock coal with low sulfur content to correspond to the burners at a low layer; establishing a coal blending volatile component function of acorresponding combustor according to the stock coal contained in each subset; and calculating an optimal coal blending combustion scheme of the corresponding combustor by taking the coal blending volatile component function as a target function and taking the inventory of inventory coal as a constraint condition. The coal blending combustion method provided by the invention has the technical effect of less coking.

Description

technical field [0001] The invention relates to the technical field of coal blending and blending combustion, in particular to an optimization method, device and computer storage medium for coal blending and blending combustion. Background technique [0002] In the actual application of the boiler, there are different problems whether the design coal type or the calibration coal type is adopted. When using the designed coal type, the boiler continuously runs at high load and the coking situation of the boiler is serious, and the workload of coking and decoking is relatively large, resulting in the need to consume a lot of manpower and material resources on coking and decoking, and the work of coking and decoking is very costly. personnel and equipment safety hazards. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, provide a coal blending and blending combustion optimization method, device a...
