General Description

The Computer Controlled Geothermal (high enthalpy) Energy Unit, "EG6C", developed by EDIBON, has the aim of introducing the student in a renewable energy, increasingly important.

This unit simulates the steam produced in the well, by using a steam generator. Then the steam produced moves a turbine by means of a steam injector, which impacts against the blades of the turbine and generates work.

According to the energy which the steam (flow, temperature and pressure) has, there will be more or less work produced by the turbine.

This mechanical work is converted into electrical energy by an electric generator suppling a load.

The unit is supplied with suitable instrumentation and sensors to monitor the most representative parameters measurements and to control from a computer.

The output energy supply an electric generator connected to a resistor. The power is measured by means a wattmeter.

The steam flow is an important variable and is measured by means of the condensed steam volume during a determined time.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
