“Create a steam circuit turbo alternator diagram for a combined-cycle power plant: natural gas to a gas turbine generator and grid transformer, gas-turbine exhaust to a triple-pressure HRSG, 100 bar 565 C main steam to an HP-IP-LP steam turbine and alternator, plus a condenser, hotwell, pumps, HRSG economizer, and feedwater return.”
看懂背後的決策。
Gas-turbine exhaust raises steam in a triple-pressure HRSG.
HP, IP, and LP stages extract work before condensation.
Both turbine trains connect to the grid through their own transformers.
Recovered condensate re-enters the HRSG through the economizer.
Use this for a high-level combined-cycle plant overview where the heat-recovery steam cycle and both electrical trains need to be clear. It is suitable for training or plant documentation.
常見問題
What is an HRSG?
A heat recovery steam generator uses gas-turbine exhaust heat to generate steam.
Why are there two alternators?
The gas turbine and steam turbine each drive their own electrical generator.
What does triple-pressure mean?
The HRSG has multiple pressure levels to recover exhaust heat more efficiently.
