Explain how proximity analysis of coal can be determined by thermogravimetric analyzer.
Proximate Analyzer (Thermogravimetric Analyzer, TGA) is used to determine:
- Moisture,
- Ash,
- Volatile matter in coal,
- Coke,
- Biomass,
- Limestone,
- Iron ore,
- Food and feedstuffs by thermogravimetric method.
It can also determine residual ash and slag combustibles in accordance with ASTM, which is widely applied in power plants, coal mines, metallurgy, food industry, chemical industry, commercial inspection, scientific research, education, etc. It could work both simultaneously and independently.
