SPECIAL CONDITIONS OF CONTRACT

1. DETAILED SCOPE OF WORK

The technical details of ESPs of Phase-I & Phase-II are as tabulated in Section-A, Clause No. 2:

Brief Scope of Work.

Some of the technical details of ESP internals installed at SLPP is briefed hereunder for

reference purpose only. Detailed scope of work as per this tender shall follow subsequently.

 Collecting electrode suspension system:

The collecting plates are made of 1.2 mm Corten steel Grade A and shaped in one piece by

roll forming. The collecting electrode has unique profile designed to give rigidity and to

contain the dust in a quiescent zone free from re – entertainment. Collecting electrodes are

provided with slots, which are engaged on the hooks welded on the suspension angles. All the

collecting electrodes in a row are held in position by a shock bar at the bottom. The shock

bars are spaced by guides.

The technical specifications for collecting electrodes [for ESP type FAA-6 X 45 (45)-132-135-

2] are as specified below:

 Nominal height of Collecting electrode plate: 13,560 mm

 Nominal width of collecting electrode: 750 mm

 Material of Construction: Corten steel Grade A as per latest BHEL standard for

collecting electrode

 Collecting electrode thickness: 1.2 mm (+/- 0.02)

Cross sectional shape for collecting electrode as displayed in figure below:

 Emitting electrode suspension system:

The most essential part of precipitator is emitting electrode system. This is supported by four

insulators. The frames for holding the emitting electrodes are located centrally between

of Revised Environmental Norms at 4 x 125 MW Surat Lignite Power Plant [Tender Ref.:

SLPP/MECH/BMD/FGD/2026-28]

collecting electrode curtains. The entire discharge frames are welded to form a rigid box like

structure and the emitting electrodes are affixed between the frames as displayed in

following figures:

of Revised Environmental Norms at 4 x 125 MW Surat Lignite Power Plant [Tender Ref.:

SLPP/MECH/BMD/FGD/2026-28]

The technical specifications of emitting electrodes [for ESP TYPE FAA-6 X 45 (45)-132-135-2]

are as specified below:

 Emitting electrode type: Spiral with hooks

 Emitting electrode size: 2.7 mm dia.

 Emitting electrode material: Stainless steel confirming to UHB 904 L

 Rapping systems:

Rapping systems are provided for collecting and emitting electrodes (CERMs & EERMs).

Geared motors drive these rappers. The hammers are positioned at an angular displacement

of 210 degree / 195 degree for collecting rapping mechanisms of 300 mm pitch / 400 mm

pitch respectively. For the emitting electrode the same is positioned at 240 degree. The

rapping system employs tumbling hammers, which are mounted on a horizontal shaft. As the

shaft rotates slowly the hammers tumble on to the shock bar/shock beam which transmits

the blow to the electrodes. One complete revolution of the rapping shaft will clean the entire

field. The rapper programmer decides the frequency of rapping. Rapping frequency chart is

given in this manual. The tumbling hammer disposition and the periodicity of rapping are

selected in such a way that less than 2 % of the collecting area is rapped at any instance. This

avoids re-entertainment of dust and puffing at the stack. The rapping shaft of emitting

electrode system is electrically isolated from the geared motor drive by a shaft insulator. The

space around the shaft insulator is continuously heated to avoid condensation.

Support Insulators & Insulator housings:

The support insulators, supporting the emitting electrode system are housed in insulator

housing. The HV DC connection is taken through a bushing insulator mounted on the

insulator-housing wall.

In order to avoid the condensation on the support insulators, each insulator is provided with

one electrical heating element. Heating elements of one pass are controlled by one
