Abstract

The invention discloses a bituminous coal quality stability evaluation method and device. The method comprises the following steps: determining a plurality of quality stability evaluation indexes of a single coal; obtaining a plurality of index values of each quality stability evaluation index and determining a standard deviation value of each quality stability evaluation index; and determining the quality stability of the single coal according to the standard deviation value of each quality stability evaluation index and the weight of each quality stability evaluation index in the quality stability of the single coal, wherein each quality stability evaluation index accounts for 100% of the weight sum of the quality stability of the single coal, so that the data quantitative evaluation of the stability of the single coal is realized, and the evaluation accuracy of the single coal is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of bituminous coal evaluation, in particular to a method and device for evaluating bituminous coal quality stability. Background technique [0002] With the development of blast furnaces, the requirements for coke quality stability are getting higher and higher, and the main factor affecting the quality stability of coke is the stability of bituminous coal quality. At present, the quality stability of a single type of coal can be judged according to the range of change (increase or decrease) of a single or multiple inspection indicators, and the overall stability of a single type of coal cannot be evaluated. Contents of the invention [0003] The invention provides a method and device for evaluating the quality stability of bituminous coal, so as to realize the quantitative evaluation of the bituminous coal stability data, thereby realizing the evaluation of the overall stability ...
