TGA 3000 Thermogravimetric Analyzer: Automated Proximate Analysis for Coal & Biomass
Simultaneous moisture, volatile matter, and ash determination for up to 19 samples in full compliance with ASTM D7582.
Executive Overview
Orbit's TGA 3000 delivers unattended proximate analysis of coal, coke, and solid biofuels. Its 19-position carousel and integrated analytical balance eliminate manual muffle furnace transfers.
Traditional proximate analysis of solid fuels requires tedious manual transfers between drying ovens, volatile matter furnaces, and ashing furnaces, exposing samples to ambient moisture re-absorption and operator handling errors.
The TGA 3000 Thermogravimetric Analyzer, available from Orbit Technologies, automates moisture, volatile matter, and ash determination in a single, unattended automated run. The instrument features a precision 19-sample ceramic carousel integrated with an internal analytical balance boasting 0.0001 g resolution.
During the test cycle, the dual-zone heating chamber raises the temperature up to 1000°C under programmed nitrogen and oxygen gas atmospheres. The carousel rotates continuously, weighing each crucible at set time intervals to record the exact mass loss curve until thermal equilibrium is achieved.
Fully compliant with ASTM D7582 and ISO 17246, the TGA 3000 reduces technician labor by over 75% while dramatically improving batch-to-batch precision for coal preparation plants, power utilities, cement kilns, and metallurgical coking facilities.
