Gasification.
In the previous report we outlined two options for gasification. During further discussions after
writing that report, Parkside have chosen to further pursue the staged approach using Burkhardt
gasifiers.
Option 1. Proceed with a staged approach and split the project into two stages. 7 x 165kW gasifiers
in Stage 1. Stage 1 will also consist of the pellet line and drier for the sawdust. Stage 2 will consist of
a further 5 x 165 kW gasifiers with the option of a drum drier to dry woodchips if the pellet market
proves to be growing strongly.
Stage 1 will consist of:
Gasification:
- 7 x 165kW gasifiers to produce 1.1MW Electrical (El) and 1.589MW Thermal (Th). This will
provide 100% of the electrical energy required on site. Gasifiers will operate 24/7 for 7000
hours p.a.
Pellet Production:
- CPM pellet press cube to produce 6mm diameter fuel pellets.
o Production capacity 4.0 T per hour. Operating 7 hrs / day in Stage 1 to make
sufficient pellets for the gasifiers. It will also operate for a further 3.5 hours / day
producing 3000 Tonnes p.a. of pellets for the domestic market. The pellet press will
operate for a total of 10.5 hours / day. Sufficient pellets will be made in 5 days to
operate the gasifiers for 7 days. The surplus being stored in a 75 Tonne finished
pellet silo.
Drying:
- Drier for sawdust, capacity 1Tonne /hr. This will be a flash drier but the required
temperature is around 270 degrees C. The residual heat from the gasifiers is just under 100
degrees C. Therefore, a small wood chip fired boiler will be required to provide the heat
source to dry the sawdust.
Stage 2 will consist of:
Gasification:
- 5 additional x 165kW gasifiers for a total of 1.96MW El and 3.12MW Th.
Pellet Production:
- CPM pellet press cube to produce 6mm diameter fuel pellets
o Fuel Pellet Production 4 T per hour. operating for 12 hrs / day x 5 days / week
o Annual fuel pellet production 10,080 Tonnes p.a.
