Online Coal Ash Analyzer
The Online Coal Ash Analyzer is used for on-line detection, measurement and control of coal ash. It is widely applied 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. It also can support the closed-loop automatic control and improve the producing benefit.
- 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.
- 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
Adaptable Wherever Level is Measured:
- Control room temperature: 0~40°C
- Storm flow installations
- Sewage plants
- Detector temperature control accuracy: ±0.5°C
- Analog quantity output:4-20mA
- Power: 220V(±10%)50Hz
- 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.
- Real-time: provide real-time online measurement for the coal which move through the belt and offer the instantaneous value and average value of coal ash in any period.
- Representative: Measure the coal that move through the belt and get over the shortage of traditional detection which is not representative because of taking little sample to analyze.
- Reliable: It can measure the material by non-contact way on the principle that the signal can pass through the material. Also it can design the most optimized measurement solution and key parts to make sure that the instrument keep steady and reliable operation according to site environment.
