1.4 MW Bleed Condensing Steam Turbine Despatched for Chemical Plant in India
Chola Turbo Machinery International (CTMI) has successfully manufactured, tested and
despatched a 1.4 MW Bleed Condensing Steam Turbine for a chemical plant in India.
Designed for a demanding process application, the turbine enables the customer to efficiently utilise available steam energy while meeting both process steam requirements and captive power generation needs.
A bleed condensing steam turbine is particularly suitable for process industries where steam is required at a specific pressure for process consumption while the remaining steam can be expanded further to generate electrical power.
What Is a Bleed Condensing Steam Turbine?
A bleed condensing steam turbine combines controlled steam extraction with condensing operation. Part of the steam is extracted or "bled" from the turbine at the required pressure for process use, while the remaining steam continues expanding through the turbine towards the condenser.
This configuration allows industries to:
● Supply steam at the required process pressure
● Generate electrical power from available steam energy
● Recover additional energy from the remaining steam
● Reduce energy losses associated with pressure reduction
● Accommodate variations in process steam demand
For chemical plants and other process industries, this provides greater flexibility compared
with systems where steam pressure is reduced solely through a Pressure Reducing Valve
(PRV).
Technical Advantages of a 1.4 MW Bleed Condensing Steam Turbine
The 1.4 MW bleed condensing steam turbine supplied by CTMI is designed to efficiently utilise the available steam energy for simultaneous process and power requirements.
Key advantages include:
Controlled Steam Bleeding
Steam can be extracted at the required pressure to meet the customer's process steam requirements while maintaining turbine operation.
Captive Power Generation
The turbine can generate up to 1.4 MW of electrical power through the controlled expansion of live steam.
Maximum Steam Energy Recovery
After the required steam is extracted for process use, the remaining steam can continue expanding through the turbine towards condenser pressure, allowing additional energy to be recovered.
Operational Flexibility
The system can accommodate variations in process steam demand while continuing to support power generation requirements.
Improved Energy Utilisation
Where steam pressure would otherwise be reduced through a PRV, controlled expansion through a steam turbine can convert a portion of the available pressure and enthalpy drop into useful electrical power while continuing to provide steam to the process.
Live Steam Test Before Despatch
One of the key stages in CTMI's manufacturing and quality assurance process is the Live Steam Test.
At Chola Turbo Machinery International, every steam turbine undergoes a live steam test before despatch. The test provides an opportunity to evaluate the turbine and associated systems under actual steam operating conditions before the package reaches the customer's site.
The live steam test enables verification of important operating and functional parameters,
including:
● Turbine mechanical operation under live steam
● Speed governing and control response
● Emergency trip and protection functions
● Vibration and bearing performance
● Lubrication and auxiliary system operation
● Temperature and pressure monitoring
● Overall operational readiness of the turbine package
Where required, customers and their representatives can also witness the live steam testing process.
This approach helps ensure that the steam turbine package is thoroughly evaluated before shipment, supporting reliable installation and commissioning at the customer's plant.

Efficient Steam Utilisation for Industrial Power Generation
For industries with simultaneous process steam and electrical power requirements, a bleed condensing steam turbine can provide an effective way to utilise available steam energy.
By combining controlled steam extraction with continued turbine expansion, the system can help industries recover useful energy, generate captive power and meet process steam requirements from a single turbine system.
The successful manufacturing, live steam testing and despatch of this 1.4 MW Bleed Condensing Steam Turbine marks another milestone for CTMI and reflects the coordinated efforts of its engineering, manufacturing, quality, testing, projects and logistics teams.
At CTMI, steam turbines are not just manufactured—they are tested on live steam before they leave our works.
