The portable coal quality detector is a kind of instrument specially designed for measuring coal ash, moisture and calorific value based on the actual needs of the production unit and using nuclear technology and microwave technology.

The instrument is portable, can be directly inserted into the coal in trains, automobile carriages or coal piles, quickly and accurately measure the ash in the coal, the instrument is flexible to use, simple to operate, and easy to carry. Suitable for power plants, docks, coal storage and transportation Units and coal units.

Measuring principle:

There is a very small amount of natural radioactive elements in the interior of minerals, and the radioactive elements in coal mainly exist in ash, and the fixed carbon and volatiles do not generally contain radioactive elements. The characteristic γ-particle flux emitted by coal has a specific mathematical relationship with the ash content in coal. The high-efficiency and highly sensitive gamma particle detectors were used to detect the characteristic fluxes of the characteristic gamma particles, and the total ash content was obtained. The coal ash content was calculated based on the load size, and the low calorific value was calculated with the moisture analyzer.
