Hazelwood 2030
- Alstom (United Kingdom)
Funding made available by both the Victoria State and Australian Federal Governments for the demonstration of low emission technologies is enabling the implementation of pilot brown coal drying technology at unit 1 of the International Power managed Hazelwood power station. This will dry the run of mine brown coal from above 60% moisture content to approximately 12% moisture content in an initial 50% feed train. It is the core component of a major upgrade programme, Hazelwood 2030 described in this article. Key features of the WTA and retrofit project can be summarised as follow: Unit 1: Installation of new turbines. Steam extraction for WTA supplying 23 kg/s. Unit output increased to between 215 and 217 MWe, with the same steam flow as the original design; Installation of boiler feed water heaters providing 3% improvement in unit boiler efficiency; Installation of a WTA fluidized bed drier sufficient to provide the fuel for 50% of the thermal heat input required for 50% cocombusiton of dried brown coal (DBC); Conversion of boiler and adaptation of the firing system to 50% co-combustion of dried brown coal and ROM brown coal; Implementation outage scheduled for 4Q, 2009; Unit 2: Installation of new turbines, unit output increased to 220 MWe, again with the same steam flow as the original design; Installation of boiler feed water heaters providing 5% improvement on unit boiler efficiency; Implementation outage scheduled for 2Q 2009. 11 figs.
