ME THERMODYNAMICS II
STEAM PLANT (BOILER)
LAB SESSION: THURSDAY 25 FEB 2010, 0800-1000 hrs
REPORT SUBMISSION: MONDAY 8 MAC 2010
The objective of this experiment is to give an experience on the principle of operation of an actual steam power plant.
1. Ten point Digital temperature indicator
2. Pressure gauges
3. Analogue tachometer
4. Dynamometer with voltmeter and ammeter,
5. Condenser timer
6. Torque meter
7. Cooling water flow meter
PROCEDURE OF EXPERIMENT
1. Before beginning the experiment, the system should be left operated as it needs time to provide stable readings. Begin the experiment when the instructor told us to do so. 2. As the system is ready and briefing session ended, schematic diagram of the system is taken and the major components of the system are identified and located. 3. The instruments of the system are located and identified. 4. The readings at the inlet and outlet of the pump, boiler, superheater, turbine nozzle, turbine and condenser.
Mass flow rate of fuel, [pic]= 31.3 kg/min
