04.09.01 GENERAL
01. This document is intended to define the basic requirements for
instrumentation system for Coal Handling Plant & Coke Sorting Plant for
COB #11 and Flux & Fuel Preparation and Plant Return Fines Handling for
SP-III coming under the 7.0 MTPA expansion of Bhilai Steel Plant (BSP)
with a view to achieve smooth, efficient, safe and reliable operation of the
process.
02. This document, read together with the Instrumentation & Automation part of
the General Technical Document (No.GS-03), General Conditions of
Contract (GCC) and other commercial terms & conditions, will form the
Contract document pertaining to Instrumentation & Control System of Coal
Handling Plant & Coke Sorting Plant for COB #11 and Flux & Fuel
Preparation and Plant Return Fines Handling which will be complied by the
Contractor while executing the package.
03. Measurement and control equipment supplied for the process will be
complete in all respect in line with this document. Any equipment /
accessories not explicitly indicated in this document, but considered
essential for proper functioning of technological equipment and process are
included in Contractor‘s scope of work and supply.
04. Monitoring, sequential operation, alarm & interlock functions for the process
& equipment of the Coal Handling Plant & Coke Sorting Plant for COB #11
and Flux & Fuel Preparation and Plant Return Fines Handling for SP-III will
be achieved through automation system. All instrumentation facilities will be
interfaced with automation system accordingly. The requirement regarding
automation system has been separately described under ‗Automation
system (level-1)‘ chapter of this Document.
05. Instrumentation system of the plant will be in general, Field Bus compatible
and will be interfaced with the automation system having Field Bus interface
modules. However, in cases, where some instruments are not available with
Field Bus compatible features, conventional instrumentation equipment
(SMART & 4-20 mA DC signal output) will be supplied. Signals from these
instruments will be interfaced through hardware input/ output modules of the
automation system.
06. All field-mounted level transmitters will be radar type. Suitable enclosures
will be provided at field for the controller/ electronic unit of the level
transmitters. Other features of the instrumentation facilities will be as
indicated in the Instrumentation part of General Technical Document
(No.GS-03). Level transmitters will measure accurately & reliably the level
of bulk solids and powders during fill cycle regardless of the dust or material
variation in density or moisture.
