Key Features
- The Automatic microprocessor based TGA is programmed to perform complete and automatic analysis of Air-Dry Basis Moisture, Ash & Volatile Constituent in Coal
- Latest design allows measurement up to 19 samples in every batch in accordance with ASTM D-7582-15 & D-7348
- Additional furnaces can be connected for increased workload to measures 38 or more samples. All the additional furnaces are programmed to be controlled by a single computer
- Both oxidizing and inert atmospheres can be maintained as per ASTM guidelines. Provision shall be made to introduce a sweep gas or a reactant gas, and to remove product of drying, de-volatilization or combustion.
- The sample balance pedestal, crucible and the crucible covers are made of ceramic material as per ASTM guidelines. The crucible and the turn table are capable of withstanding high-temperatures and different furnace atmospheres and is not susceptible to wrapping at high temperature.
- The furnace is programmed to have maximum temperature control up to 1000°C with variable temperature ramp rate .The furnace cover of the analyser is supported by two shafts for better stability and support.
- Instrument has two thermocouples which includes one thermocouple for over - temperature protection for safety and the other one to measure and record temperature near the test crucible.
- The versatile and powerful software allows the instrument to store minimum 7 programmes for Moisture, Volatile Matter and Ash determination at temperature programmed by the user depending on the nature of sample.
- Multiple calibration points for Balance & Temperature
- High Precision Temperature Controller ensure Controlled, Precise and Quick Temperature rise
- The system can also calculate the LOI Calorific Value, Fixed Carbon and Hydrogen in the samples based on the values of the parameters obtained
- The instrument is configured with a built-in high Precision Electronic Scale to ensure precise and accurate weighing of the samples
- The software which controls the operation of the TGA has inbuilt programable memory for storage of data and analytical methods along with several other powerful and user-friendly features
- Graphical representation of the analysis & reporting
- Pre calibrated at factory as per the ASTM methods for proximate analysis Auto stop facility is provided
- Latest software features LIMS enabled with Automatic Data Collection, Tabulation and Printing of all test results
- Advanced dust suction and exhaust system fitted to remove the exhaust gases generated during the experiment
