1.0 INDENT OF SPECIFICATION:

In MTPS-II/600MW plant, a vacuum evacuation and pressurized conveying fly

ash system has been installed during commissioning for the fly ash disposal from all

the 72 No’s of ESP hoppers i.e., (4 passes viz A, B, C & D x 2 paths x 9 fields per

path). From these hoppers vacuumised evacuation and conveying of the Dry Fly ash

into 4 No’s of 20MT Buffer hoppers takes place by the use of 6 No’s of 600mm-Hg &

3600 T/Hr capacity industrial vacuum pumps and then from the Buffer hoppers, the

pressurized pneumatic ash conveying system is in service to transport the Fly ash

collected at Buffer hoppers to 2x4152 MT RCC main Fly ash silo through 4 No’s of

conveying streams which are operated and monitored from a PLC Control Room. 6

No’s of Transport Air Compressor’s of 1237 litre/second @2.75 kg/cm2 capacity have

been utilized for the purpose of fly ash transportation from ESP Buffer hoppers.

With the existing Fly ash evacuation and conveying system @ MTPS-II/ 600MW

plant, the entire fly ash collection from the Boiler could not be handled and conveyed

out to the fly ash silos from ESP hoppers, especially during the Indian coal firing with

an ash content of more than 25%. Practically only 2800 Tons/Day fly ash collection is

able to be handled and conveyed out to main silos, with the existing capacity of ash

handling facility @ ESP. The enormous quantity of excess ash is getting collected

(1200 Tons beyond 2800 Tons/Day of conveying capacity) and dumped inside the ESP

hoppers and subsequently respective fields are not functioning. To manage this

situation, the ESP hoppers are manually unloaded through the spool piece, down to

the ESP floors, and loaded to the tippers with JCBs and transported to the Ash dykes,

to manage the unit to run with full load capacity. These works are carried out every

day to avoid any breakdown, loss of generation or any abnormal occurrence which

may happen while the design hopper storage capacity exceeds beyond the permissible

limit @ ESP hoppers, i.e., only 17.5 Tons for 8 hours time.

In order to convey out the excess fly ash generation, an administration

approval was accorded vide : per (TANGEDCO) proceedings (CMD) No.399/

Dt.30.08.2016 for supply, erection, testing and commissioning of two nos additional

fly ash conveying pipe lines from ESP to silo. However, the procurement and the

installation works were not carried out due to various reasons such as non-feasibility


83

of ash evacuation and conveying without proposal for compressors, phased manner

implementation proposed, tenders got lodged due to technical reasons etc. Also the

scenario got changed for the consideration of Indian coal firing completely without

imported coal. In this context a complete new proposal to handle 1200 Ton per day fly

ash with new set of compressors, D-pumps and silo are required as per the present

situation and hence the old proposal was dropped.

a) Ministry of power vide letter dated 28.04.2020 has advised all the

generating companies who are importing coal for blending purposes may make best

efforts to replace their imports with domestic coal. The ministry of power further

stated that thermal power plants are exhorted to import coal for blending purposes, if

and only if, the requisite quantity and quality of domestic coal is not made available.

Based on the directions given by ministry of power, in order to reduce the country’s

dependence on imports for saving foreign exchange flow, an thermal plants would

examine the possibilities and options of reducing imported coal requirements. In this

context, 600 MW/MTPS-II plant has to install an additional 1200TPD capacity of fly

ash handling facility, to implement the advice of MOP/GOI, to substitute the imported

coal with domestic coal.

b) The MTPS-II Boiler has been designed for a fuel firing rate of 427.8 TPH

with design coal and 455.3 TPH of worst coal with an ash content of 40.3% in design

coal and 47% in worst coal. Hence the design coal firing will generate a quantity

(427.8x24x40.3%) 4137 TPD fly ash and the worst coal firing will generate

(455.3x24x47%) 5135 TPD fly ash where as the existing fly ash evacuation capacity is

only 2800 TPD practically. Hence the augmentation is necessitated.

c) In order to manage the excess fly ash collection @ 72 No’s of ESP hoppers,

beyond 2800 Ton/Day, the augmentation of additional capacity is essentially required

to dispose Fly Ash to the existing silo so as to run the unit without any load restriction

and breakdown due to excessive fly ash storage beyond its load capacity @ ESP

hoppers.

d) The fly ash thus collected and conveying off to the existing 2x4152 MT RCC

silo by the augmentation of additional fly ash capacity will prevent the falling

down/collapse of ESP structure. In additional to this, it will avoid (i) pollution due to


84

spilled out and manually unloaded excess fly ash into ESP floors and (ii) the

transportation cost to the board.

e) In spite off cost savings on collection and transportation expenses of ESP fly

ash, now by the proposed installation of Additional Fly ash conveying system, the

additionally collected and conveyed ash to the silo will be sold out from the silo

storage to the Cement manufacturing industries and other construction related

agencies which will cater the revenue benefits to the Board.(i.e., approx. 1200

Ton/Day x Rs.708.75/- per ton = Rs.8,50,500/- (Rupees Eight Lakhs Fifty Thousand

and Five Hundred only) per day, after the successful commissioning of the additional

fly ash augmentation facility at MTPS-II.

f) It will also be ensured for healthy and safe operating conditions of the unit on its

power generation process beside the neat and hygiene industrial surroundings, inline with

the suggestions and directions of Pollution Control Board.

g) It is a mandatory requirement as per the notification of Ministry

2.0 GENERAL DESCRIPTION OF EXISTING SYSTEMS:

In MTPS-II/600MW plant, a vacuum evacuation and pressurized conveying fly

ash system has been installed during commissioning for the fly ash disposal from all

the 72 No’s of ESP hoppers i.e., (4 passes viz A, B, C & D x 2 paths x 9 fields per

path). From these hoppers vacuumised evacuation and conveying of the Dry Fly ash

into 4 No’s of 20MT Buffer hoppers takes place by the use of 6 No’s of 600mm-Hg &

3600 T/Hr capacity industrial vacuum pumps and then from the Buffer hoppers, the

pressurized pneumatic ash conveying system is in service to transport the Fly ash

collected at Buffer hoppers to 2x4152 MT RCC main Fly ash silo through 4 No’s of

conveying streams which are operated and monitored from a PLC Control Room. 6

No’s of Transport Air Compressor’s of 1237 litre/second @2.75 kg/cm2 capacity have

been utilized for the purpose of fly ash transportation from ESP Buffer hoppers.


86

With the existing Fly ash evacuation and conveying system @ MTPS-II/

600MW plant, the entire fly ash collection from the Boiler could not be handled and

conveyed out to the fly ash silos from ESP hoppers, especially during the Indian coal

firing with an ash content of more than 25%. Practically only 2800 Tons/Day fly ash

collection is able to be handled and conveyed out to main silos, with the existing

capacity of ash handling facility @ ESP. The enormous quantity of excess ash is

getting collected (1200 Tons beyond 2800 Tons/Day of conveying capacity) and

dumped inside the ESP hoppers and subsequently respective fields are not

functioning. To manage this situation, the ESP hoppers are manually unloaded

through the spool piece, down to the ESP floors, and loaded to the tippers with JCBs

and transported to the Ash dykes, to manage the unit to run with full load capacity.

These works are carried out every day to avoid any breakdown, loss of generation or

any abnormal occurrence which may happen while the design hopper storage

capacity exceeds beyond the permissible limit @ ESP hoppers, i.e., only 17.5 Tons for

8 hours time
