triveni combines the advantage of proven time-tested components and customized design to meet customer needs.

PErformancE undEr varying grid conditionS

triveni’s turbines are designed to take variation in grid frequency and load throw-off. Its robust and reliant steam turbo-generators have delivered exceptional performance in these conditions.

Part load oPEration, with oPtimizEd EfficiEncy

our steam turbo-generators are built with design features that allow safe and efficient operation at part load conditions with optimized efficiency reducing power and steam cost.

varying ProcESS StEam / PowEr dEmand conditionS

triveni’s steam turbo-generators are designed to operate with a wide range of power / steam demand.

Its ability to function reliably in diverse operating conditions is pre-tested using high-end software and proven based on the on-site performance data.

comPact SyStEm layout

the skid-mounted design (steam turbine, Gear box and oil storage / pumping system) of triveni offers the following benefits:

- smaller foot print and occupies lesser area

- lower civil cost

- Quicker installation and assimilation into plant setup

- easier maintenance

low PrESSurE/ low tEmPEraturE StEam conditionS

triveni’s design versatility lies in the fact that we also design turbines for applications with low pressure /low temperature steam (example: cement waste Heat recovery, bottoming cycle power generation). our turbines are optimized for energy recovery while maintaining its robustness.

Triveni designs, manufactures and delivers the following types of turbines:

Condensing Turbines These types of turbines maximize the conversion of potential energy in steam into kinetic energy. During this process, the steam is expanded to a pressure level, which is below atmosphere to increase the energy recovery. The condensing process is achieved by a closed loop cooling system.

In some cases, the inlet steam to the turbine is available at different pressure levels (eg. Cement Waste Heat Recovery). In such cases, injection type models are provided.

TYPES:Uncontrolled Extraction •Controlled Extraction

ParamEtEr rangE PowerGeneration • Upto30MW Steaminletpressure • Upto140Bar(a) Steaminlettemperature • Upto540deg.C

Back-pressure Turbines The back-pressure turbine application is ideally suited for co-generation applications and offers the best efficiency in a balanced power / process heat scheme. The initial investment in this type of machine is also considerably lower, due to the absence of a condensing system and its auxiliaries.
