Abstract

The invention discloses a method for on-line analysis of coal quality. The method comprises: spraying coal fines to be measured into oxygen flow for combustion; by a spectroscopic analysis method and combining the remainder oxygen content and the water vapor content in flue gas, analyzing and calculating the calorific value, the volatile compound content, the carbon content, the sulfur content, the phosphor content and the like of the coal fines. A system for the on-line analysis of the coal quality comprises a combustion chamber, a flue, a flow controller, a coal weighing feeder, a signal acquisition control module, a spectrum acquisition analysis assembly, and a signal processor; the combustion chamber, the flue, the flow controller and the coal weighing feeder are connected with the signal acquisition control module, the combustion chamber and the flue are connected with the spectrum acquisition analysis assembly, and the signal acquisition control module and the spectrum acquisition analysis assembly are connected with the signal processor. The method and the system have the beneficial effects that: problems that laboratory measurements cannot be carried out continuously and rapidly are solved, the devices can run with long term stability in a live environment, and chronicity and stability of the measurements can be ensured.

Description

technical field [0001] The invention relates to the technical field of automatic measurement, in particular to an online analysis method and analysis system for coal quality. Background technique [0002] For the measurement of calorific value, volatile matter, and element content of coal, laboratory methods are currently used. The laboratory test method takes a long time to test and generally takes several hours. Coal powder needs to be manually sampled, and the prepared sample is manually put into the test equipment for test analysis. After the analysis is completed, the equipment needs to be cleaned manually, and the test cycle is long. It is necessary to manually put in the sample and take out the gray sample after the test, which cannot be done automatically and continuously. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides an online coal quality analysis method and analysis sys...
