TRAINING PERIOD: 13.2.2012 TO 18.2.2012 We submit our sincere thanks to Vandayar Engineering College for allowing us
the sugar factory and once again we submit our opportunity for acquiring the practical knowledge about the powerproduction & sugarto undergo a inplanttraining inheartiest thanks to thiru arooran sugars limited for giving such a wonderfull production.
THIRU AROORAN SUGARS LIMITED
INTRODUCTION OF THIRU AROORAN SUGAR FACTORY:
The sugar mill was established and commissioned during 1989 with an installed capacity of 2500 TCD and got subsequently expanded to 5000 TCD in1999 and then to 6000 TCD in 2007.
Fig 1.Out look of the thiru arooran sugar factory.A distillery was started with 60 KLPD in 1993 and subsequently expanded to 105 KLPD in 2007. The sugar plant is also annexed with a co-generation plant of 28.92
MW and the power is pumped to the state grid.
The sugar mill is situated in the coastal zone and entire cane area allotted to our factory lie in the Cauvery and vennar basin.
TERRA ENERGY SYSTEM:
In the co generation power plant 2 types of boiler is used:
1.KCP boiler
2.TBW boiler
2 types turbine is used:
1. GEC turbine
2. SIEMENS turbine
KCP BOILER:
The steam is produced in the boiler by burning the bagasse at the bottom. The temperature produced in the boiler is about 480 deg celcius. So, that the water in the pipe gets heated and produce the high pressure steam.
Fig. KCP BOILER Fig.ASH removing liver & burning area of bagasse.
The pressure of steam produce in the boiler is about 66kg/cm square. Nearly 70TPH ( tones per hour) of water is converted to high pressure steam by the KCP boiler. In this KCP boiler only bagasse can used as fuel for burning.
KCP BOILER OVER VIEW:
The major disadvantage of this boiler is ash handling. Because, the ash handling conveyer in not available. So, the ash can be removed only by man power.
TBW BOILER:
The process of producing the steam in the TBW boiler is as same as the KCB boiler. The temprature of the TBW boiler during the steam production is already 480 deg celcius.
Fig. steam pipes in the TBW boiler
The boiling of water in TBW boiler is nearly 70TPH.
The steam pressure produce in the TBW boiler is 42kg/cm square. It is multifuel boiler because of both coal & bagasse can used as a fuel.
TBW BOILER OVER VIEW:
*******************************************************************
GEC TURBINE:
It is 3 blade turbine & also this is an old model turbine. It produce power up to 18.68MW.
Fig. GEC turbine with 3 blades.
the high pressure steam coming from the TBW boiler is fed into the GEC turbine so, it rotates at high speed nearly 10,000 rpm but, the alternator can produce the required output in the speed of 1500rpm inorder to reduce the speed of turbine the gear box is used.
******************************************************************
GEC TURBINE OVER VIEW:
The gear box is full different size gear wheels so the speed can be adjusted.
*******************************************************************
SIEMENS TURBINE:
It is a multiblade turbine. & latest model turbine.
Fig. Siemens turbine.
Through this we can produce 9.8MW.
The steam coming from the KCP boiler is applied to SIEMENS and then usual process of power production is undertaken.
COOLING TOWER:
CONCEPT:
This is the main part of the terra energy system. It is mainly used for cooling the hot water comes from the output of the turbine.
CONSTRUCTIONAL DETAILS & PROCESS:
The hot water is taken to the top of the tower through the large size pump & poured forcedly. The poured water is passes through the nozzle. The nozzle is the small hole like structure which spins the water & sent down.
A cooling tower contains nearly 432 nozzles. It is technically called 1segment.
Fig .nozzle
95% of the cooling tower is made up of wood. Because, it absorbs heat. Inside the cooling tower many wood pieces are constructed in cross position & these wood segments are constructed in row manner so, that the water flows through it rude manner.
Fig .wood construction in cooling tower.
The water gets cooled due to the water flow through the row of woods in a cross position .so, the heat water is cooled by the obsorbing of heat by wood & the atmospheric air.
Mastic compound is a paste like structure & black in colour. It is maily used for preventing the leakage of water in the cooling tower.
Fig .mastic compound applied in woods.
It is applied in the corner & joining of the two wood pieces so, that the water leakage is avoided. These mastic compounds are applied by the manual according to the requriments.
COOLING FAN:
Cooling fan is fixed at the top of the cooling tower. It contains 9 blades each blade is 5.5 feets in length. These fan is connected through the gear box. So, that the speed can be controlled the gear box is connected through the long shaft.
Fig.cooling fan in cooling tower.
The shaft is connected to the induction motor. So, that the cooling fan tends to rotate. The main function of the cooling fan is to absorbs (or) suck the atmospheric air through the openings in both sides of the tower.
The process of the cooling fan is which it exhaust out the hot air present inside the cooling tower in to atmosphere so the water is cooled & finally reach the cooling basin. Again the cooled water is taken through the pump & feed in to boiler
NOTE: The cost for constructing the cooling tower is nearly 20 lakhs.
