The Net Calorific Value (NCV) is determined by calculation and is equal to the Gross Calorific Value (GCV) less any heat lost due to moisture present in the fuel and various chemical processes. The NCV is more representative of the heat available in practice when fuels are combusted in boilers and furnaces[1]. The NCV value is a method of quantitatively classifying waste Feedstock, as shown in the table below[1].
| Classification Property | Unit | Class 1 | Class 2 | Class 3 | Class 4 | Class 5 |
|---|---|---|---|---|---|---|
| Net Calorific Content (as received) | MH/kg (mean) | >=25 | >=20 | >=15 | >=10 | >=6.5 |
