Characterization of Solid Fuels:
Proximate Analysis: |
- Used to determine the moisture content, volatile matter, fixed carbon and ash content in the solid fuel.
- To determine water content, few grams of fuel is heated around 378 K till it attains constant weight.
- Volatile matter is determined by heating the sample at 1173 K.
|
| Ultimate Analysis: |
- Used to determine the major elemental composition of the solid fuel.
- Nitrogen content is determined by chemical method.
- Sulphur content is evaluated by burning the fuel to convert it into SO4 followed by precipitation method. Calorific value can be determined by bomb calorimeter.
