POWER QUALITY IMPROVEMENT

•INSTALLATION OF AHF ON TRFO NO

# 704 & 710

Saving of 58 KW i.e. Rs 13.78 Lacs

Adv: Reduce distortion of the normal

electrical current waveform, transmitted

by nonlinear loads

Future Planning: Power supply of DCS system

to be connected through AHF (To avoid DCS

card failure)

Major Energy Conservation Project-1 (2017-18):

INSTALLATION OF AHF (Board Plant)

Page 22: 19th CII NATIONAL AWARD FOR “ EXCELLENCE IN ENERGY ...

Advantage: •150 KW/15.65 Ton steam saving.

•Better steam Power balancing.

•Flexibility in online load shifting..

Efficiency gain at TG

Before: • At Low Load, Increased temp of 2nd

extraction (Less Thermal Expansion)

causing less generation

•Less enthalpy drop in 43MW TG

After :

•Transfer 2MW load on 43 MW TG.•Due to increase in load at 43MW, 2nd stage

expansion improved

•Extraction Temp drop by 3-4 0C i.e. extra

generation of 1.5KWH/ Ton of extraction

steam

PA Fan for Boiler No-8 & 9 :

Before: •To Full Fill the Primary air requirement, PA

Fan was running with its standby

equipment in Parallel operation.

•High power consumption .

•Less plant reliability due to non-availability

of stand-by Fan.

After :•Installed new Higher capacity Fan which

will run independently

•Other Fan (existing) will serve as Stand-by

Advantage: •75 KW saving

•System reliability increase by

adding them as stand-by

Major Energy Conservation Project-3 (2017-18):

Page 24: 19th CII NATIONAL AWARD FOR “ EXCELLENCE IN ENERGY ...

Optimization of Circulation

pumps -16 MW Cooling Tower:

Before: • 2 No pumps was running on full rpm while

head & flow requirement was less.

•1 no pump was standby

• High power consumption .

• Vacuum Maintained at 0.95mmWC

After :•Trial taken by throttling the valve & optimize

the flow & head by maintaining the Vacuum of

0.95mmW C.

•After Successfully trial 1 pump converted from

DOL to VFD and remaining 2 kept same

•Optimize the rpm from 1000rpm to 650 rpm

Blowing Sequence:

Before: • Earlier Soot blower done in zig-zag &

vertical sequence

•Steam temp was less than 435 0C

•Power house facing problem with steam

temp.

•Less Generation

After :•Monitored the steam temp according to soot

blower sequence & where we get the temp

gain (Specially at inlet & outlet of boiler bank),

we increased the effectiveness of soot blowing

by changing its sequence/repeatation.

•Pressure/Flow optimization at furnace soot

blower.Advantage:

• Steam temperature increased from 435 0C to 445 0C.

•Saving of 37KJ/T of steam generate

•No dilution

•Resulted increase in inlet Solid

Advantage:

• 41 Ton/day steam saved

• Condensate saved.

• Evaporator efficiency improvement

Steam Flow control with limit function to prevent transient high Steam flow

Innovation Project-1:

• Low Boiler Efficiency (82%)

Problem

• Maintain const Bed Temp (930 Deg)

• Maintain Const Feed & Air

Objective•Consistence regulation of Boiler fuel

•Compartment Slum as per Plant demand

Challenges

• High Peak Steam Demand 480 to 500 T/Hr against avgdemand of 430T/Hr

Constraint

• Peak demand of Digesters at Pulp Mills

Reason

Source of Idea: Boilers inefficiency due to steam demand peaks of digester

Process conditions: With the inherent nature of Digester batch process, the steam flow

consumption increased to more than 32TPH from 20TPH within span of 2 minutes. This hampered

Boiler and TG operation and sudden surge in fuel consumption with related process upsets

Problem Encounter
