Online Coal Quality Analyser

Introduction: The analyzers allow monitoring of actual coal quality online directly on the belt conveyor, can determine the calorific value, ash content and flow rate within specified time interval. Use of the units will improve the excavation efficiency and allow optimization of coal consumption which leads to significant cost reduction. The content of non-combustibles is evaluated based on attenuation of dual gamma radiation. The measurement method conforms to all nuclear safety regulations.

The GE3000 series coal analyzers represent the third generation of Enelex on-line radiometric analyzers. Its evolution utilizes more than 25 years of practical experience and knowledge in the field of contactless coal quality monitoring and also needs of our important customers.

It is intended for perimeter protection, especially in difficult conditions. It can detect intruders in total darkness without any additional illumination,in fog, rain or through bushes. The thermal imaging cameras used detect the heat given off by objects, so it offers exceptional performance in detection of persons, animals or machines.
