Modeling and optimization of coal blending and coking ...

The remainder of this paper is organized as follows. Section 2 describes how the coal blending and coking process is analyzed. Section 3 introduces our new coke quality prediction model, based on Gaussian functions and XgboostCSVR. Section 4 proposes our MPSO-based blended coal cost optimization method. Finally, Section 5 presents and analyzes our experimental results.

CN104312609A - Coal blending method for controlling ...

The invention discloses a coal blending method for controlling the basicity index of coking coal. The coal blending method comprises the following steps: 1, measuring the coalification degree and the coke optical tissue structure of the coking coal, measuring the ash composition, and calculating the basicity index; 2, dividing the coking coal into four big classes and sixteen small classes ...

Blending of coals to meet power station requirements

Coal blending in its simplest form is the mixing of available coals to produce a blend which combusts well to produce heat and/or power. In the past, the focus for plant operators was largely on blending the maximum amount of the cheapest and/or most readily available coals with the minimum amount of

Coal Blending - an overview | ScienceDirect Topics

Many coal blending theories have been proposed for producing coke of a specific targeted quality by blending various kinds of coals. For example, Jo (1965) considered that coal consists of two components, a fibrous component and a caking component, and that increasing the strength of fibrous component (coal rank) and the addition of a suitable amount of caking component (caking property) …
