Model: LM 2500G4+ DLE
Power Output: 33.37 MW
Generator Maker: ABB
Gas Turbine Generator Model: BDAX71-193ER
Gas Generator Output: 45,625 kVA
Frequency: 50 Hz
Type: Dry Low Emissions (DLE) for reduced NOx emissions
Fuel Type: Typically natural gas or light liquid fuels (specific fuel type may vary depending on the setup)

Turbine Characteristics:

The LM 2500G4+ DLE is designed for high efficiency and low emissions, making it ideal for both simple-cycle and combined-cycle applications.
The gas turbine converts energy from the combustion of fuel (typically natural gas) into mechanical energy, which drives the generator to produce electrical power.

Maker: Luo Yang Steam Turbine Factory
Steam Turbine Model: QF-J25-2
Power Output: 12.5 MW
Generator Voltage: 10.5 kV
Type: Condensing or back-pressure steam turbine (specifics depend on the setup)

Turbine Characteristics:

The steam turbine utilizes steam produced by the HRSG to drive a turbine generator to produce additional electrical power.
The steam turbine is typically part of the combined-cycle process, where it improves overall plant efficiency by utilizing waste heat from the gas turbine.

HRSG Characteristics:

The HRSG captures the exhaust heat from the gas turbine and uses it to generate steam.
The steam is then fed to the steam turbine to produce additional electrical power.
The HRSG is designed for high efficiency in recovering heat, optimizing overall power generation.

Total Power Output (Combined Cycle): 45.87 MW
- Gas turbine: 33.37 MW
- Steam turbine: 12.5 MW
Generator Voltage (Gas Turbine): Typically in the range of 10-20 kV (depending on specific configurations)
Generator Voltage (Steam Turbine): 10.5 kV
Frequency: 50 Hz (standard frequency for many countries)

HRSG Steam Temperature: 475°C (very high temperature steam, ensuring efficiency in power generation)
HRSG Steam Pressure: 4.95 MPa (the pressure at which steam is generated in the HRSG, contributing to higher efficiency)
Gas Turbine Exhaust Temperature: Varies based on load and operating conditions, but typically ranges from 450-550°C in a gas turbine of this type.

Plant Type: Combined Cycle (Gas + Steam)
Primary Fuel: Natural gas (common for LM 2500G4 turbines, though it could also use light liquid fuels)
Secondary Fuel: Waste heat from the gas turbine exhaust, used to generate steam
Cycle Efficiency: Typically higher than a simple-cycle plant due to the combination of gas and steam turbines.

Control System: Advanced digital control systems (likely using a platform such as ABB's System 800xA or a similar integrated control system).
Monitoring: Sensors to monitor gas turbine exhaust temperature, steam pressure, steam temperature, and HRSG performance.
