Proximate Analysis Equipment for Coal, Coke, Biomass, and Solid Fuels
Overview
Qualitest offers a complete range of Proximate Analysis Equipment designed for accurate and efficient determination of key components in solid fuels such as coal, coke, biomass, and solid waste materials.
Our instruments combine advanced automation, high precision, and reliable performance—making them ideal for laboratories, power plants, cement and steel factories, and research institutions that require fast and consistent analysis of fuel quality and combustion characteristics.
With Qualitest’s proximate analysis solutions, users can easily determine moisture, ash, volatile matter, and loss on ignition (LOI), as well as calculate fixed carbon and calorific value.
Applications
- Determination of moisture, ash, volatile matter, and loss on ignition (LOI) in coal, coke, and solid biomass fuels
- Calculation of fixed carbon content and gross calorific value
- Determination of carbon content in fly ash and clinker
- Suitable for coal testing laboratories, power generation plants, steel and cement industries, environmental labs, and research facilities
