TRIVENI GROUP

Triveni Group (est. 1933) is one of the oldest diverse business

conglomerates in India with core competencies in the energy,

sugar, water and wastewater treatment sectors.

Triveni established itself as a Sugar producer way back in 1933

and expanded to 3 major sugar plants in India (at Khatauli,

Deoband and Ramkola) with a combined capacity of

about 25,000 tcd. Making Triveni one of the largest producers

of sugar in India, with production rivalling that of the

entire West Indies.

It was a natural diversification from sugar to sugar machinery

for Triveni. The company started the manufacture of sugar mill

machinery in the mid 1960s. Over the years, capability has been

extended to design, engineer, manufacture and commission

complete sugar plants. Triveni has installed over 45 sugar plants

and has carried out major expansion works for over 18 sugar

plants. Triveni, through a group company, has a collaboration with

Sugar Research International, Australia (SRI) to manufacture and

market the latest products of SRI in the Indian sugar industry.

INTEGRATION OF DIVERSE STRENGTHS

Triveni started the manufacture of steam turbines in

1968, to provide steam turbine solutions for Process Industries

and Power Plants. Today Triveni is a market leader in India with a

market share of more than 60%.

In 1975, Triveni started producing high speed gears and

gearboxes for turbine applications as well as for other

industrial applications. Triveni currently has strategic alliance with

Lufkin Industries Inc., USA to produce gearboxes upto

50 MW capacity

In order to provide various solutions in small power, Triveni

became the packagers of Vericor Power, USA (JV of Allied Signal,

USA and MTU, Germany) for Gas Turbines upto 10 MW capacity

and Waukesa, USA for Gas Engines upto 3 MW capacity.

Triveni commenced the manufacture of surface pollution control

equipment in 1986 and started undertaking the execution

of turnkey water and wastewater treatment plants, thereafter.

The company has gained expertise in water treatment solutionsfor municipal water, sewage treatment, sludge removal,

power plants, steel plants, refineries, distilleries, dairy industries,

common effluent treatment plants, etc. Triveni presently has

a License Agreement with U.S. Filter / Envirex, USA, part of

Vivendi Water, France.

An elaborate manufacturing facility, integrated

with R&D centre, ensures the making of world-class

steam turbines. A pressurised clean room for production and

assembly of blades, nozzles, diaphragms and rotors,

CNC machining for crit ical components represent our

uncompromising attitude towards producing quality turbines.

Triveni has in-house facilities for Hydro-test of turbine casings,

Zyglo for crack detection, radiography, ultrasonic and

dynamic balancing. Each and every turbine manufactured by

Triveni is subjected to extensive in-house testing, including

Mechanical Run Test (MRT) at 110% of design speed with

gearbox fitted. This ensures smooth running, governor response,

safety trips, vibration levels and sound levels are established

before delivery of turbines.

In condensing turbines the energy available in the live inlet steam

is used to the extent possible by expanding the live steam in the

turbine below atmospheric pressure (vacuum). The steam is finally

exhausted from the turbine at vacuum to the surface condenser

where the latent heat of exhaust steam is transferred to the coolingwater. The condensed steam is then returned back to the boiler as

feed water. These turbines are straight-condensing type. These

type of turbines find application where steam is utilized only for

power generation.

The condensing turbine may also have bleed points (uncontrolled

extractions) to satisfy steam demands at medium intermediate

pressures. This provision is applicable when the bleed (medium

pressure) steam volume demand is low and pressure variations

can be tolerated. These turbines are of bleed cum condensing type.These type of turbines find application mainly for power generation

where bleed steam is required for feed water heating (HP heater,

LP heater and Deaerator requirement) and / or where bleed steam

is utilized to meet small process demands.

The condensing turbine with one controlled extraction point is

possible. This extraction steam is also used to meet process steam

demand at intermediate pressure when volume demand is high

and pressure variations cannot be tolerated. These turbines are of

extraction cum condensing type. These turbines are typically used

for co-generation where the turbine meets both the power and

steam demand of the process plant. In these type of turbines the

power generated can be maintained more or less at a steady level

despite variation in process steam demands.

In some cases it may be necessary to have both bleed and

controlled extraction steams from the condensing turbine. Theseturbines are of bleed cum extraction cum condensing type.

Back pressure turbines can either be single stage or multi-stage

which are often used in industrial plants. The turbine serves as a

reducing station between boiler and process steam header. These

turbines can either be used for drive application (sugar mill drive,

sugar fibrizor / shredder drive, pump drives and so on) or powergeneration application in which case the turbine drives the generator.

These turbines are straight-back pressure type. These type of

turbines find application where back pressure steam is fully utilized

to meet process demands. The power generation is incidental to

the process steam demand.

The back pressure turbine may also have bleed points (uncontrolled

extractions) to satisfy steam demands at medium intermediate

pressures. This provision is applicable when the bleed (medium

pressure) steam volume demand is low and pressure variations

can be tolerated. These turbines are of bleed cum back

pressure type.

The back pressure turbine with one controlled extraction point ispossible. This extraction steam is also used to meet process steam

demand at intermediate pressure when volume demand is high

and pressure variations cannot be tolerated. These turbines are of

In some cases it may be necessary to have both bleed

and controlled extraction steams from the back pressure turbine.
