LAB

MANOMETRY LAB

• This Lab. Consists of :

• Sensor• Indicator• Scale/Recorder

Bourdon Tube

Manometer

• It is a pressure measuring instrument, usually limited to measuring pressures near to atmospheric.

• The term manometer is often used to refer specifically to liquid column hydrostatic instruments.

PYROMETRY LAB

• This lab deals with the instruments related to temperature measurement like:

• Thermocouple

• Resistance Temperature Detector (RTD)

Thermocouple

• Used for the measurement of high temperature with a dual element made of Aluminum 16 Gauge.

RTD – Resistance Temperature Detector• used as a primary sensing element

• operates on this principle of changes in electrical resistance

• Temperature Range:183°C – 540°C • Element Resistance at 0°C : 100 ohm• Accuracy:+/- 0.5

AUTOMATIC CONTROL SYSTEM LAB

• Deals in automating the equipments and feeding routes.

• Provides safe operation under all plant disturbances and component failures.

• Requires 24 Volt DC, 4-20 mA to excite all the controls.• System installed in BTPS is “OLD RUSSIAN

SYSTEMS”.• These are ACS (Automated Control System) which are

slowly being replaced by DCS (Digital Controlled Systems).

PROTECTION & INTERLOCKING LAB

• Interlocking : It is basically inter-connecting two or more equipments so that if one fails other can perform the task.

• Main Equipments of this lab:o Relayso Fuseso Circuit Breakers

Relays• It is a protective device. • It can detect wrong condition in electrical circuits by

constantly measuring the electrical quantities flowing under normal and faulty conditions.

• Types:o Current Relayo Potential Relay

Fuses• It is a sheet piece of metal.• It melts if a heavy current flows through it and

breaks the circuit.• Usually silver is used as a fuse material.• Types:

o Semi Enclosed Rewire able Fuseo H.R.C Cartridge Fuseo Miniature Current breakers

FURNACE SAFEGUARD SUPERVISORY SYSTEM

• In this lab, fuel firing system is monitored in the furnace.

• Oil is sprayed first for firing of coal in furnace so Light Diesel Oil (LDO) is used for ignition.

• The rate of oil flow is 6000 L/hr before firing.
