Kogan Creek Solar Boost Project, step-by-step
Solar energy will be used to boost the conventional coal-fired electricity generation process at Kogan Creek Power Station. The steps below outline how the two technologies will be combined.
1. Cold water from the air-cooled condenser is piped to the boiler feedpump.
2. Water is diverted to the solar field.
3. The water is heated using solar energy and converted to steam.
4. Steam from the solar field is further heated and used to power the intermediate pressure turbine to generate electricity.
5. Coal from the stockpile is fed to the power station.
6. Pulverised coal is blown and ignited in the boiler.
7. Water is heated in the boiler to produce steam.
8. Steam drives the turbine. The addition of the solar field reduces the amount of steam bled back to the feedwater heater, meaning more steam is available for the electricity generation process.
9. The turbine spins the generator. A powerful electromagnet is mounted on the generator shaft and when it rotates,
10. Electricity is transported to customers via high voltage transmission lines. At peak solar conditions, the solar field will enable Kogan Creek to generate an extra 44 megawatts of electricity.
11. Steam is condensed into water in the air-cooled condenser and then pumped back to the boiler feedwater pump for reuse.
12. A filter system cleans fly ash from the boiler exhaust gases before they are discharged up the chimney. produces electricity in the surrounding generator windings.
13. Ash is used in rehabilitation of the Kogan Mine site.
