ET 833 Steam Power Plant 1,5kW with Process Control System
Education / GUNT Hamburg / Thermal Engineering and HVAC / Power Engines and Machines /

The ET 833 steam power plant is particularly designed for training purposes in the area of power plant technology and thermal system tests. Due to the high degree of complexity the system operates very similar to real large scale plants.
  An oil-heated steam boiler and an upstream electrically heated superheater create hot steam for a single-stage industrial turbine. The turbine is loaded via a direct current generator and the generated energy is supplied back into the grid. The exhaust steam from the turbine is condensed and fed back to the boiler. All relevant parameters are recorded by sensors and displayed in the process control system (PCS). The operation of the system can be monitored completely from the PCS. The control system operates based on modern touch screen technology. The system records critical operating states in alarm lists and warning messages and the affected system components automatically go into emergency-shutdown.
  Feed water treatment with ion exchanger and metering pump for chemicals; a feed water tank and the fuel tank are integrated on the frame of the system. The result is a compact unit that just needs to be supplied with cooling water. 

  If not enough cooling water is available a closed-cycle re-cooling system can be set up together with the additionally available ET 833.01 Cooling Tower.

  The test plant is built according to the legal safety regulations and includes the mandatory safety features. The installed steam boiler is type-tested and does not require special approval within the EU. The system includes comprehensive documentation material.
