BACK PRESSURE STEAM TURBINE BASED COGENERATION PLANTS

(Saturated steam)

These steam turbines are mainly designed based on the process industries needs. It is

custom built and is replacement to the existing Pressure reducing stations (PRS) and

Pressure reducing and de-superheating stations (PRDS), which are widely used in the

process industries. The basic objectives are to utilize the heat energy available in the

steam rather than wasting by throttling it in PRV or PRDS.

Pressure range : Inlet pressure: Maximum 44 Kgs/cm (Saturated): Back pressure: Maximum 8 Kgs/cm (Saturated)

Steam Flow : Maximum : 15 tons/hr

Minimum : 3 tons/hr

Power : Maximum : 1 MW

Minimum : 200 KW

Salient features:

The power generated through this system is incidental, hence no extra fuelrequired.

Superheating not required, hence cost of fuel for superheating completelyeliminated.

No complications and hassles of maintenance and cleaning of Superheater. The power generated thus also qualifies for the carbon credit. Options of Alternator and Induction generator available for fluctuating steam

loads.

Options of Imported and Indian turbine module

BACK PRESSURE STEAM TURBINE BASED COGENERATION PLANTS

(Superheated steam)

These steam turbines are mainly designed based on the process industries needs. It is

custom built based on the process steam requirement. Steam is generated in the boiler

at high pressure and superheated to the required level and then passed through the

Back pressure turbine wherein the back pressure is set for Process pressure

requirement. The turbine can be coupled either to the Alternator or Induction

Generator, depending on the Steam and Power consumption pattern of the process.

Pressure range : Inlet pressure: Maximum 44 Kgs/cm 440C Superheat.: Back pressure: Maximum 8 Kgs/cm.

Steam Flow : Maximum : 75 tons/hr

Minimum : 3 tons/hr

Power : Maximum : 5 MW

Minimum : 200 KW

Salient features :

The power generated through this system depends on the process pressurerequirement and pressure level raised in the Boiler. Lower the process

pressure, better the power output.

Superheating required, hence cost of fuel for superheating adds on to theoperation cost, which is negligible when compared to the power generated.

Parts in contact with steam has better life as compared to saturated steamturbines as the quality of steam is better and free from moisture.

The power generated thus also qualifies for the carbon credit. Options of Alternator and Induction generator available for fluctuating steam

loads.

Options of Imported and Indian turbine module.

BIOMASS BASED POWER PLANTSPower plants based on Biomass as fuel. Fuel like Paddy husk, Groundnut shell, Fire

wood, Bagasse and other Agro waste & Municipal waste is burnt in biomass fired

boiler to generate steam at high pressure. The steam thus generated, is further

superheated to remove moisture and then passed through a condensing steam turbine.

Steam coming out of Turbine is passed through a Condenser which creates a negative

guage pressure in the turbine, so that maximum output is extracted from the turbine.

The condensate coming out of the Condenser is pumped back to the boiler circuit by

Condensate evacuation pumps.

Capacity : Upto 10 MW

Fuel : Paddy Husk / Groundnut shell / Bagasse / Fire wood / other

Agro waste and Municipal waste

Services :

Design, Engineering, Supply, Erection & Commissioning of Bilers,Turbines, Condensers, Ejectors, Cooling towers, Pumps and all related

accessories of power plant on Turnkey basis.

COAL BASED POWER PLANTS

Power plants based on Coal as fuel. Fuel like Indian coal and imported coal is burnt

in boiler to generate steam at high pressure. The steam thus generated, is further

superheated to remove moisture and then passed through a condensing steam turbine.

Steam coming out of Turbine is passed through a Condenser which creates a negative

guage pressure in the turbine, so that maximum output is extracted from the turbine.

The condensate coming out of the Condenser is pumped back to the boiler circuit by

Condensate evacuation pumps.

HEAT RECOVERY STEAM GENERATOR BASED POWER PLANTSIn most of process industry, waste heat is generated which is utilized in generating the

steam through a waste heat recovery boiler. The steam so generated, if not required in

The plant process could be utilized through a condensing steam turbine and generator.

This would generate power which could be used for captive consumption. In case the

power generation is in excess of plant requirement, then by synchronising with grid

the excess power so generated can be fed to the grid. In case the power generated is

less than the plant demand then, differential power could be drawn from the infinite

grid.


Source : Gas from most of the sources, and various composition.
