| Biomass/Oil Comparison | |
|---|---|
| a) 1 litre of gas-oil produces approximately 8.0 kWhrs (in 80% efficient boilers) | |
| b) 1kg woodchip (26% moisture content) produces 3.1 kWhrs | |
| c) 1 litre of gas-oil is replaced by 2.4 kg woodchip (26% moisture content) | |
| 2.0 kg wood pellets (8% moisture content) | |
| 2.3 kg grain (13% - 18% moisture content) | |
| d)     average woodchip - | 220 kg/m3 |
| average wood pellets - | 680 kg/m3 |
| average grain - | 880 kg/m3 |
| *max. output potential reduces with increased water, bark, soil/sand/grit content. The maximum outputs are only achievable with clean, dry woodchip free of contamination and with low bark content. | |
| If in doubt send a sample of your proposed fuel. | |
