Plant Commissioning<br />

Steps:<br />

1.1 Cold process with just nitrogen throughput <strong>at</strong> <strong>at</strong>mospheric pressure.<br />

1.2 Calibr<strong>at</strong>ion tests <strong>of</strong> the feeding and burner system in the plant.<br />

1.3 Cold process with just nitrogen throughput <strong>at</strong> 5 bara pressure.<br />

1.4 Cold process with nitrogen and steam wood powder <strong>at</strong> <strong>at</strong>mospheric pressure.<br />

1.5 Controlled he<strong>at</strong> up <strong>of</strong> lining to 1000 C.<br />

1.6 Warm process with just nitrogen throughput <strong>at</strong> 5 bara pressure.<br />

1.7 Warm process with ‘synthetic air’ (oxygen/nitrogen blended) and steam<br />

wood powder <strong>at</strong> <strong>at</strong>mospheric pressure.<br />

1.8 Warm process with ‘synthetic air’ (oxygen/nitrogen blended) and steam wood<br />

powder <strong>at</strong> 2 bara pressure.<br />

1.9 Warm process with pure oxygen and different wood powders up to 5 bara<br />

pressure<br />

Primarily, bark, stumps and wood residues<br />

from pulp mills will be tested.<br />
