Reduction in Power Generation cost by utilization of available low cost fuel- Lignite

Objective

Problem /Background

Boiler is not design for 100% lignite firing.

Available Imported coal cost Rs/MCV is higher compare to Lignite.

Volatile matters is very high in lignite which increasing high temperature in convection zone of boiler during firing of Lignite .

Lignite have high VM & due to same it get self ignite & create fire risk in fuel handling system


Erected one new discharge chute (size 20’’) with manual isolation gate from Lime screen discharge chute which divert lime stone in coal feeding conveyor belt.

Provision for Raw meal extraction from Raw meal silo

Raw Meal feeding system at Boiler Lime bunker.

Looking to VM Boiler furnace draft reduced from -25mmWc to -10 mmWc which resulted saving of Aux. power

Action Initiated




By this modification, Up to 80 % Lignite fired in boiler . For 100% Lignite firing Boiler FGD proposal in under process.

Better reaction between Lime Powder & SOx.

Fire risk minimized near belt conveyors by blending of lime stone with lignite at belt conveyor.

Saving of Aux. Power at ID fan – 33.24 Lacs/annum

Saving of amount 687 Lac/Annum by selection of Lignite fuel.

Results


4. MV Drive Installation in BFP

Objective

Background of Project

TPP Power generation is directly depend upon power demand by Cement plant.

TPP PLF varying between 40 to 85 % as per load requirement & due to same DOL- BFP taking high power at low MW Generation & that was increasing the aux. power consumption.

Analysis & Implementation required to reduce APC of BFP at low MW Generation of TPP.

4. MV Drive Installation in BFP - Analysis

Analysis

To reduce power cost ,it is very important to optimize the BFP power consumption . By cause

& effect analysis following causes has been identified

Plant Running on Low capacity

Losses due to Recirculation

Losses due to Feed control valve throttle at low feed water demand to boiler drum

DOL Operated BFP

Implementation

Team TPP adopted Engineering & technological change in BFPs by installing of MV Drive in BFP with proper PID & Logic implementation as follows-

Feed water discharge pressure set point = Boiler Drum pressure + 7 Kg/Cm2( Head loss+ Bend Loss + Piping/tube friction loss)


4. MV Drive installation in TPP BFP

Results

Throttling losses minimised by opening Feed control to maximum

BFP recirculation become zero at low load.
