Power Generation
Steam turbines from 5 MW to 60 MW: thermal, co-gen & captive power
Industry Overview
India's thermal and captive power sector depends on the uninterrupted performance of steam turbines operating under continuous load. Keshav Enterprises has deep OEM-era expertise (our engineers were trained by turbine manufacturers before founding the company), giving us the ability to reverse-engineer, manufacture, and overhaul every major sub-system of a power plant steam turbine to OEM tolerances.
Key Applications
- Steam turbine major and minor overhauling
- Turbine erection and commissioning
- Lube oil system flushing per ISO 4406:99
- Rotor dynamic balancing and alignment
- Emergency stop valve manufacturing
- Filter elements and strainers supply
Key Challenges We Solve
Continuous High-Load Operation
Steam turbines in power plants run at 3000–3600 RPM under sustained full-load conditions, placing extreme stress on bearings, seals, and rotating assemblies.
Lube Oil Contamination
Particulate and water ingression into the lube oil system can rapidly degrade bearing surfaces. ISO 4406:99 cleanliness targets must be maintained continuously.
Thermal Expansion in Steam Lines
High-temperature steam piping undergoes significant thermal cycling. Without properly engineered expansion joints, piping stress causes flange leaks and turbine nozzle damage.
Rotor Vibration & Balance Drift
Deposit build-up and erosion cause progressive balance shift in rotors, increasing vibration and accelerating bearing wear if not caught early.
Products We Supply for Power Generation
Lube Oil Filter Elements (180 GPM)
Maintains ISO 4406:99 cleanliness in turbine lube oil systems, protecting journal bearings and thrust bearings from abrasive wear.
- Glass fiber fleece VG media, 6–25 µm fineness
- IS27 anti-static spec for synthetic oils
- Triveni, Siemens, BHEL OEM compatible
Steam Crossover Bellows
Absorbs thermal expansion between HP/LP turbine sections and the crossover pipe, eliminating stress transfer to turbine nozzle flanges.
- High-cycle SS bellows, EJMA standard
- Operating temp up to 550°C
- Custom flanged ends to OEM dimensions
Babbitt Journal & Thrust Bearings
White-metal lined bearings precisely machined to OEM profiles for turbine rotors, critical for shaft stability at high speed.
- White metal (Babbitt) poured & precision-machined
- All turbine makes: Triveni, Siemens, BHEL, KKK
- Interference fit verified on CMM
Emergency Stop Valves
Safety-critical valve that trips the turbine on overspeed or lube oil low pressure, manufactured to OEM trip pressure settings.
- CNC machined body from EN8/EN19 forgings
- Spring-loaded trip mechanism
- Tested at 1.5× working pressure before dispatch
Vibration Monitoring Probes (Shinkawa-compatible)
Proximity probes for continuous rotor vibration monitoring per API 670, enabling predictive maintenance before bearing failure occurs.
- Shinkawa, Bently Nevada compatible
- Eddy-current non-contact sensing
- Alert and danger setpoints per API 670
Turbine Oil Pumps (Main & Aux)
Supplies pressurized lube oil to all bearings. Auxiliary pump takes over during run-up and run-down when main shaft-driven pump output is insufficient.
- Gear pump design, fitted to turbine skid
- All major OEM dimensions available
- Relief valve set to OEM pressure specification
Pleated Panel Air Filters (Control Room & Turbine Hall HVAC)
Replacement HVAC filters for power plant control room AHUs, turbine hall ventilation units, and electrical switchgear room air coolers, keeping cooling air clean and protecting sensitive equipment from coal dust and fly ash contamination.
- F7 efficiency to capture fine fly ash and coal dust
- Galvanised steel frame with synthetic media
- Standard AHU sizes stocked; custom on request
- Metallic mesh pre-filter also available for first-stage duty
