45 - 90% depending on steam requirements and process integration
70 - 190% depending on district heating requirements and process integration

Boiler design

Water tube boiler with natural circulation
Single pressure or double pressure (reheat, e.g. 140 bar and 25 bar)

Operating time

At least 8000 hours without shutdown for manual cleaning

Boiler efficiency

91% - 94% depending on fuel moisture

Emission values

Better than European requirements (large boiler or WID)

Fuel flexibility

Fuel moisture content: 10 - 5%

Auxiliary burner

Not necessary

In-house power consumption

<2.5% of fuel heat input

Availability

Better than 96%.
