PGCV
Portable GCV Analyser is used to analyze the composition of coal, as well as heating value according to the actual condition of the coal. It will display the ash content and gross calorific value. The instrument can be directly plugged in to Coal Pile in Station Wagon, Truck, or any other Coal transportation vehicle for 60 seconds and the measurement result can be instantly read out.
Working Principle The low energy γ photon anti-scattering method is adopted in the system to measure the ash & moisture content. The low energy γ photon mass attenuation coefficient is related to atomic number; when the γ photons inject into the coal sample, the strength & shape of γ which is reflected back is related to the ash content of coal. System will measure the ash & moisture content by the reflected signal; while the Gross Calorific Value will be calculated out by the microcomputer based on the Moisture and the Ash content.
