Analyzing Coal Quality

Article's tools:

A device that measures coal quality without putting the user's health at risk won a gold medal at this year's Councours Lépine innovation exhibition in Paris.

The device, called the Gamma Natura coal quality analyzer, was developed at the EMAG Center for Mining Electrification and Automation in the southern Polish city of Katowice.

The judges in Paris praised the innovative technology and the fact that the analyzer had been developed to meet the needs of industrial users. The design is a model example of ties between a research institution and the corporate sector, the judges said.

Coal analyzers are used to determine the content of ash in coal. They are widely applied in industry. However, most of them contain radioactive isotopes, which makes them a potential health hazard. Users of such devices had repeatedly expressed an interest in products free from such isotopes. In response to these calls, EMAG decided to develop a device like that.

The new analyzer was designed by a team made up of Teresa Sikora, Boles³aw Czerw, Marek Kryca, Edward Kuæmierz and Ireneusz Motyka. The device makes it possible to quickly determine the ash content and moisture of fine coal samples and their calorific value.

The Gamma Natura analyzer takes it name from the technology it employs. The measurement method relies on the correlation between the content of ash in coal and the natural gamma radioactivity of coal. Previous laboratory analyzers used artificial gamma ray sources. The Gamma Natura uses the microwave method to determine coal moisture. The calorific value is derived from the data on ash content and moisture.

The new analyzer is safe and environmentally friendly, the inventors say. It can be used in coal mines, research laboratories, power plants and combined heat-and-power plants.
