Online Coal Ash Analyzer

DF-5753 Online Coal Ash Analyzer

The Online Coal Ash Analyzer (DF-5753) is used for on-line detection, measurement and control of coal ash & finds wide application in coal mines, coal washing plants, coal blending plants, coking plants, coal-fired power plants, steel plants and coal terminal, etc. It is especially suitable for on-line coal ash analysis on the entire belt conveyor during the coal transportation process.

Working principle

On the basis of double energy γ ray absorption method, the coal ash content can be calculated by processing data of the two rays after passing coal attenuation.

Technical parameters

Measurement accuracy:

. When the ash content is between 0 and 15%, error ≤±0.5%;

. When the ash content is between 15% and 30%, error ≤±1.0%;

. When the ash content percentage is beyond 30%, error ≤±2.0%;

Measurement time: 1~3 mins

Belt speed: less than 5m/s

Particle size of coal sample: less than 50mm

Materiel thickness: 50mm~300mm

Measurement requirement: continuous measurement and without lacking materiel
