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 range: 5%~50%
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
Environment temperature: -20~45°C
Control room temperature: 0~40°C
Detector temperature control accuracy: ±0.5°C
Analog quantity output:4-20mA
Power: 220V(±10%)50Hz
Safety
The safety of sealed sources meets the requirements of GB4075. Dose equivalent rate at 1m of instrument surface≤2.5μSv/h meets requirements of radiation protection in GBZ125-2002. It will not harm operator in regular use.
