Co-Generation Plant Under Implementation

What is Co-generation?

In a normal sugar plant, back-pressure turbine is used which makes available low-pressure steam which is used as sources of heat for evaporating water from cane juice, and at the same time generates enough electric power to meet the captive requirement.

But in a Co-generation plant, a condensing turbine is used. Also steam at much higher pressure is used. For requirement of low pressure steam, the same is bled form turbine at an appropriate point. This configuration gives much higher thermal efficiency, and as a result, from the same quantity of bagasse much higher generation of power is achieved. And the surplus electric power is sold to grid or to other users.

Main Features of the planned 30MW Co-gen plant being implemented :

Pravara Sugar Factory, which crushed around 10Lakh Tonne cane , will supply the entire quantity of bagasse and also 3000cu.m/hr. bio-gas to power plant.

Power plant will supply during :

• Crushing (170 days):
  Power - 6.6 MW
  LP steam - 110 TPH
• Off seasm (160 days)
  Power - 1.5 MW
  LP Steam - 11 TPH

Optimization /reduction of steam consumption in sugar plant :

Boiling house of the sugar plant has been modified with a view to minimizing steam consumption, so that in the co-generation plant maximum steam is used for power generation.

Major equipments in Co-generation plant :

• Major equipments in Co-generation plant
• 1 x 30 MW bleed / extraction cum condensing turbine including all auxiliaries, control & instrumentation, condenser, HP heater.
• 1 x 30MW Alternator & accessories including AVR, relay, metering & control panels, synchronizing panel, 11 KV switch board.
• Complete automation system to operate boiler and turbo-alternator fully automatic.
• Water treatment system consisting of RO plant and mixed bed D.M. plant.
• Cooling Tower, Induced Draft 3 cell, 3000 Cu .m./hr. Complete with cooling water pumps, piping, valves etc.
• Steam piping - high pressure and low pressure piping, valves, PRDS etc.
• EOT crane - 70T/5T. for turbine house.
• Bagasse handling system, ash handling system.
• Effluent treatment plant
• Compressed air system, air conditioning and ventilation system, fire fighting system.
• Tankages
• Switchyard, transformer to step up from 11 KV to 132 KV
• H.T, L.T panels, cables, bus ducts.
• Civil foundations, buildings like office, canteen, time/security office, internal roads, boundary.
• Raw water reservoir.
