Description

1. Technical field

[0001] The invention belongs to the field of automatic measurement technology and the field of application of artificial intelligence technology, in particular to an instrument and system for elemental analysis of coal quality in industrial production process and on-line measurement of industrial analysis indexes. 2. Background technology

[0002] With the development of the national economy, the consumption of raw coal has continued to increase. In the past two years, the supply of coal resources in the country has been tight, especially the coal used for electric power is in an all-round emergency. Coal supply is increasingly market-oriented and diversified, resulting in increased fluctuations in coal quality, miscellaneous coal types, and increased difficulty in controlling coal quality into the furnace, which makes the coal fired by the boiler deviate from the designed coal type, and the stable combustion of the boiler is damaged, resulting in obvious e...
