A mobile laboratory-scale steam plant for experiments in thermo dynamic principles. It helps students to understand:
A mobile frame contains all the parts of the test set. An electric pump draws from a reservoir to deliver water to an electrically-heated boiler. The boiler includes a safety valve, water level gauge and blow-downcock. The boiler produces steam to turn a two-cylinder steam motor. The used steam from the motor outlet passes through a mains water-cooled condenser, then down to a waste tank or to a measuring vessel (supplied). The equipment includes al l instruments needed for the experiments. These include a band-brake dynamometer with a digital torque and speed display, to measure and display motor speed, torque and power. Thermocouples connect to a digital temperature display to measure and display temperatures at key points in the test set. Athrottling calorimeter allows students to measure the dryness fraction of the steam. Two mechanical gauges show the boiler and engine inlet pressures.A meter shows the electrical power supplied to the heaters in the boiler.
