Cross Belt Coal Analyzer

Elemental Online Analyser for Coal applications is designed on using the latest and revolutionary new technology of Pulsed Fast Thermal Neutron Activation (PFTNA). This Analyzer is able to measure across belt width of 1600mm. The system includes the widely used and highly reliable BGO detector and processing electronics for Real Time Analysis of the material flowing on the Conveyor Belt. The system feature an unique Automatic Radiation Protection System and is equipped with Radiation Shielding fence. The CNA system offers an unique and enhanced protection against ionising radiation when generator is ON. Unlike PGNAA system which are designed using Cf252 isotopes, there is no need for shielding when generator is switched OFF. As a result, at a given distance from the CNA3, radiation is Zero when compared to Cf252 based systems. An ARPS (Automatic Radiation Protection System) fence is placed around a 1.0m radius of the CNA3 to ensure total safety during analyser ON condition during its operation. Neutron Emitting Module is electrically controlled and operated. This working principle called the PFTNA technique ensures 100% safety with ZERO radiation hazards when the system is powered OFF. There are no issues degradation of performance with time or the half life decay and subsequent intensity drop in PGNAA based systems. The Neutron Generator is able to maintain a constant neutron flux throughout its life. Also the Neutron Source life directly dependent on usage and belt running unlike Cf252 based systems that need replacement of the Neutron Source after a fixed period irrespective of the usage of the source.
