Rankine Cycle Steam Turbine Model BSG 012
Sci-tech Rankine Cycle Steam Turbine Model BSG 012 trainer serves to familiarize students with the components and principle of operation of a steam generator and enables them to examine the characteristic values of the system. The numerous safety devices of the steam generator can be tested and checked using various monitoring devices. If the steam generator is operated without the steam turbine, the generated steam is directly liquefied in a condenser and fed back into the evaporation circuit via a tank. As all components are clearly arranged on the front panel, the cyclic process can be easily monitored and understood. Sensors record the temperature, pressure and flow rate at all relevant points. The measured values can be read on digital displays. At the same time, the measured values can also be transmitted directly to a PC via USB. Optionally ‘Sci-CalR’ data acquisition software DAQ or SCADA can be included.

Item Description
FEATURES
- Laboratory-scale steam generator for wet or overheated steam
- Characteristic values of a steam boiler
- Various safety and monitoring devices
- Setting up a complete steam power plant in conjunction with the steam turbine
Sci-tech Rankine Cycle Steam Turbine Model BSG 012 is used to drive bulb loads or for heating system. Steam generators and steam engine together form a steam power plant. Steam power plants work according to the Rankine cycle which is still one of the most important industrially used cyclic processes. Steam power plants are mainly used for electrical power generation.
The steam generator and the axial steam turbine together form a complete laboratory-scale steam power plant.

The steam generator has been constructed according to the Technical Regulations for Steam, pressure-tested and is equipped with all legally required safety devices.
Shown below is an example model of a steam turbine system based on the Rankine Cycle. The cycle includes superheating and reheating to prevent condensation at the high-pressure turbine and the low-pressure turbine, respectively. The cycle also has regeneration by passinextracted steam through closed feed-water heaters to warm up the water and improve cycle efficiency.
The Saturated Fluid Chamber block models a separate saturated liquid volume and saturated vapor volume and is used to create the boiler and the condenser
