The Chair of Energy Process Engineering has a laboratory and a technical center with various test facilities.

Basic tests for fuel analysis as well as ash and combustion behavior are carried out in accordance with DIN or DIN-compliant standards. Fuel analysis includes short analysis, elemental analysis, determination of the calorific and heating value and sieve analysis. In the ash and slag analyses, the melting behavior and chemical composition of both fuel ashes and batch samples, e.g. from combustion tests, are examined. In addition, kinetic data on the ignition and combustion behavior of fuels in the ignition furnace and batch reactor are determined.

The energy process engineering laboratory has been offering internships for school students since 2005. These have always been well received, with five to ten pupils signing up every year over the last two decades to get to know the laboratory and the work that goes on there.

We recommend the student internship in the laboratory for students from the 9th grade onwards.

Main tasks:

• General collaboration in the energy process engineering laboratory
• Assistance with sample preparation
• Application of various chemical and physical measuring methods
• Independent fuel and water analyses

The student internship can be started at any time of the year and lasts 1 - 2 weeks.
