2. ACKNOWLEDGEMENT
The experience of In-plant training at JK PAPER LIMITED Unit:Central Pulp Mills has
developed my knowledge as in technical operation for which I thank the management of
the mill and technical department of the mill.
I would like to express my intense feeling and gratitude toward
Mr.H.K sharma (GM-HR),
Mr.Mahesh Bhat (Sr.GM-PRODUCTION),
Mr.Mohit Tyagi(C.M-PAPER MACHINE PROCESS).
For his co-operation during my training period.The credits also goes to HODs
shift In-charge who have helped and co-operated with me during my training period.
I express my deep sense of gratitude to Dr.Vivek Kumar for arranging my training.

Whole material balance calculation based on J.k CPM data.
This calculation change accoroding to different –different data .
All part balance show in this calculation.
And all cy and some of the flowrate and Efficiency of cleaner and screen
And loss all are mention in its desire part
This material balnce change accoroding to different –different data
Which I mention above .
Whole material balnce done by my best knowledge and guidence of my mentor

47. STEAM AND CONDENSATE SYSTEM OF PM-2
INTRODUCTION
Paper dryer or cylinder are the most popular method of drying a sheet of paper. In the
drying process steam is introduced inside the paper dryer at varying pressures depending on the
type of paper being manufactured.Steam condenses inside the drying cylinder and gives up its
latent heat.The condensate layer,non-condensibles,scales inside dryer shell,dryer surface
contamination,dryer shell,air film,paper and water vapour all offer resistance to heat
transfer.Improvement in dryin will be possible by quickly removing the condensate,keeping it in an
agitated state ,removing non condensables , evacuating dryer pocket humidity,keeping proper felt
tension.
In practice a typical sheet with 55-65% moisture enters the dryer and leaves with a
moisture content of 3-7%.Taking an average inlet and outlet moisture content of 65% and 5%.7.769
t/hr water has to be removed for production of 4.5t/hr .Thus sufficient heat is to be supplied to
evaporate this water together with supply of sufficient air to carry away the water vapour produced.
