Steam turbines and energy recovery systems
Impulse and reaction turbines from 50 kW to 180 MW, built on an optimised flow path with a modular system — plus direct-drive energy recovery sets from 3 to 10 MW.
Overview
Overview
Glorinda Turbines is driven by a team of experienced techno-entrepreneurs with decades of expertise in the design, manufacturing and support of steam turbines and related systems. Our capabilities include after-sales service, refurbishment and support for critical components.
Our work combines proven design principles, advanced engineering tools and deep industry knowledge to create flexible and efficient turbines. Manufactured with high-quality materials and precise craftsmanship under strict quality standards, these turbines deliver reliable performance and long service life.
What we offer: steam turbine generator sets; energy recovery systems; and modernisation, refurbishment and upgrading of existing steam turbines to improve efficiency, increase output and extend service life.
Our manufacturing approach combines in-house expertise with carefully selected outsourcing of machining operations. Partner facilities are thoroughly evaluated, and every stage of outsourced work is subject to strict quality control and close supervision. From raw material procurement through component machining, assembly and final testing, every step follows a proven in-house process.
Detail
Design and construction
Optimised flow path with modular system
Standardised modules are arranged according to application needs, creating compact, efficient and durable turbine packages. This ensures high reliability in industrial operations with heavy load variations while maintaining excellent internal efficiency.
The modular design reduces development cost and time, simplifies manufacturing and speeds up spare part availability. Key modules include the emergency stop valve, control valve casing, casing sections, pedestals, labyrinths, bearings, standardised blade profiles and guide blade carriers.
Core components
Steam enters through the flanged emergency stop valve into a tube-shaped valve casing, where up to four individually operated double-seated valves control the live steam flow. Inside the high-pressure casing, a cast nozzle chest houses individually designed nozzle segments for optimal steam distribution.
The casing is symmetrical to minimise thermal stresses, horizontally split and secured with pretensioned flange bolts, made of alloyed cast steel, with sufficient openings for borescope inspection. The rotor is manufactured from a solid forging and undergoes tensile, ultrasonic and crack testing. Blades are precisely milled from solid material in 13% chromium steel, with damping wire on control wheel and last stage blades. Shaft sealing uses non-contact metallic labyrinth or brush seals.
Turboset scope
Turbosets can be supplied as complete package designs or as individual installations on a concrete foundation. Key components include:
- Multi-stage steam turbine
- Gearbox, or direct-driving unit if required
- Generator, 2-pole or 4-pole
- Lube and control oil system, installed separately or integrated into the package
- Electrical engineering and control system
- Auxiliary plants such as condensers, condensate preheating systems, elevation units and secondary cooling systems
Control system
Measured values are monitored in the local cubicle and transmitted via three independent PROFIBUS connections to the Turbine Supervisory Cubicle. Generator control, protection, voltage control and synchronisation sit in the Generator Supervisory Cubicle. The control and safety philosophy is programmed in a Siemens S7 CPU and complies with VGB standard VGB-R 103 M and IEC 45-1. Overspeed protection operates on dedicated hardware with three independent channels, each testable during turbine operation.
Detail
Energy recovery systems (ERS)
Glorinda Energy Recovery Systems are designed using advanced thermodynamic principles and proven simulation tools, minimising the number of components. The result is a machine without a gearbox and with a simple lubricating oil system, delivering high efficiency, easy operation and low maintenance.
Ten features distinguish them:
- Double pedestal construction — bearing support at both ends for extended reliability, especially in dry and saturated steam applications, avoiding the frequent shutdowns caused by steam gland or bearing failures in conventional overhung designs.
- Direct drive, no gearbox — turbine and generator directly integrated, giving a compact footprint and eliminating a complex forced-feed lubrication system and costly gearbox components.
- Tailored multi-stage design — customised for specific steam conditions, achieving superior efficiency to single-stage designs.
- Rivet-less bladed design — rotor blades machined with integral shrouds for longer blade life and lower disc clearances.
- Multi-control valve option — 2 or 3 sequentially operated control valves for high efficiency at part load.
- Common base frame — turbine and generator factory-fitted on a single frame, easy to install without extensive foundations.
- Fully automatic control — PLC-based, with push-button automatic start, push-button or automated shutdown, and monitoring with fault detection.
- Anti-vibration mounts — no special civil foundation required, enabling installation on upper floors without extensive civil work.
- Induction generator — simplified grid connection with automatic power import reduction based on package output.
- Remote monitoring via IoT app — real-time data on turbine speed, vibration, bearing temperatures, steam parameters, power generation and generator winding conditions.
ERS units cover 3 to 10 MW, with steam inlet pressure up to 30 bar and inlet temperature up to 300 °C.

FAQ
Frequently asked questions
What size range do you cover?
Steam turbines from 50 kW to 180 MW, across back-pressure, condensing, extraction with back-pressure and extraction with condensing configurations. Energy recovery systems cover 3 to 10 MW.
What are the inlet limits?
Steam inlet pressure up to 140 bar and inlet temperature from saturated steam up to 540 °C, with exhaust or back pressure up to 20 bar and extraction pressure up to 70 bar(a). Speeds run up to 16,000 rpm and enthalpy drop from 100 to 1,400 kJ/kg.
Why choose an ERS over a standard turbine?
Where the duty is 3 to 10 MW and simplicity matters, the ERS has no gearbox, a simple lubricating oil system, double pedestal bearing support, a common base frame and anti-vibration mounts that remove the need for a special civil foundation — it can even be installed on an upper floor. It also has an induction generator for simplified grid connection and remote monitoring through a mobile app.
