Important Features

The Laboratory Scale Unit is designed and developed to enable students conduct experiments to study various functional aspects of Steam Power Plant and its components. The Unit consists of the following important components:

  • Boiler with a Super Heater to generate super heated steam
  • Turbine, Generator and a Loading system to absorb, measure and dissipate the energy transferred from the steam to the turbine.
  • Condenser Heat Exchanger to condense steam exhausting from the turbine
  • Cooling Tower and Pump to cool the condensate from the Condenser and feed the water back to the Boiler.

The Boiler unit is fed by a Fuel Tank and the Feed Water. Feed Water Treatment includes Regenerating-ion exchange and chemical metering. The water-steam circuit can be operated in closed, Open or partially open modes. All components of the unit are designed and fabricated as per the established norms for safety of devices.

All relevant properties and parameters will be measured using Sensors and Transducers and important parameters are displayed on the Control Panel – HMI. The Unit is self sufficient and complete with instrumentation, PLC based monitoring and control and ‘Sci-CalR’ based data acquisition and processing.

In addition to the basic studies related to the steam power plant and its components, the equipment  provide all arrangements of measurements and data acquisition to conduct wide variety of experiments related to properties of steam, single cylinder steam engine, flow through nozzles, heat  transfer in power plant components, feed water treatment and cooling tower performance.

Steam Plant Simulation Software

This software simulates a single burner, fuel gas fired boiler for training boiler plant operators, and instrumentation and process control personnel. The boiler can be brought online and fully loaded in a manner that closely follows an actual boiler start up. The simulation includes 3 element / 1 element drum level control, cross limited fuel air ratio control and a burner management system that follows the requirements set down set down in NFPA 8501 Chapter 2 Single Burner Boilers. The boiler is equipped with double block and single vent valves on the main burner and pilot. The dynamics of the boiler can be easily changed to mimic various sizes of boilers. Win Boilers Sim makes extensive use of animation. Steaming, valve position, flame size, drum level, fan and feed-water pump are all animated variables that change with the appropriate process or controller variable.
