Condensing Steam Turbines
Maximum steam energy utilization for electricity generation. Straight condensing, extraction and double controlled extraction types
What is a Condensing Turbine?
A condensing turbine is capable of maximally utilizing the full energy of the inlet steam flow. Exhaust steam is directed to a condenser where deep vacuum is created, allowing maximum energy extraction from the steam.
This type of turbine is used by energy companies that want to supply consumers with as much electricity as possible. Condensing turbines are the foundation of modern thermal power generation.
Types of Condensing Turbines
Choose the optimal configuration for your needs
Straight Condensing
Direct CondensationSteam thermal energy is fully converted into mechanical energy (torque). Mechanical energy is used for electricity generation.
- Maximum steam energy utilization
- Application in in-house power stations
- Blowdown use for deaerator
- Optimal for electricity generation
Extraction Condensing
With Controlled ExtractionOne of the most versatile units from an operational standpoint. Provides constant pressure steam through controlled extraction under various turbine load conditions.
- Controlled steam extraction
- Membrane or throttle valves
- Closed-loop feedback mechanism
- Maximum cycle efficiency
Double Extraction Condensing
Dual Controlled ExtractionSingle-cylinder design with extraction control valves at two different stages to provide constant pressure steam at predetermined values.
- Two extraction pressure levels
- Automatic adjustment
- Operational flexibility
- Optimization for seasonal loads
Operating Principle
How a condensing turbine converts steam energy
Steam Supply
High pressure and temperature steam is supplied to the turbine inlet nozzles
Expansion
Steam expands in the flow path, transferring energy to the rotor blades
Condensation
Exhaust steam enters the condenser where it turns into water
Generation
Torque is transferred to the generator for electricity production
Control System
The control system operates using closed-loop feedback mechanism for precise control of steam parameters and power.
Pressure Measurement
Consumer-side pressure is measured and fed back to the control system
Error Signal
Based on the error signal, the control system actuates the control valve
Control Valves
Membrane or throttle valves change the opening area to regulate pressure

A condensing turbine fully utilizes steam energy by directing exhaust steam into a condenser under vacuum. A backpressure turbine releases steam at elevated pressure for use in technological processes. Condensing turbines provide maximum electricity generation.
Condensing turbines are used at power plants where the main goal is maximum electricity generation. They are also used at industrial facilities as in-house power stations (IPS) to ensure independent power supply.
An extraction condensing turbine allows extracting part of the steam at an intermediate stage for process needs, while the remaining steam is directed to the condenser. This provides flexibility in simultaneous production of electricity and process steam.
Double controlled extraction turbines allow obtaining steam at two different pressures for different technological processes. This is a universal solution for enterprises with diverse steam and electricity needs.
