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.
