Hot gas generator

The hot gas generator (HGE) has been part of the technical equipment at the Institute of Technical Combustion since October 2024. The device, funded by the German Research Foundation, was put into operation in 2022 and was previously used at the former Institute of Power Plant Engineering and Heat Transfer.

 

The hot gas generator proves to be a valuable tool for the experimental investigation of high-temperature processes. It demonstrates its capabilities in particular when analysing heat transfer in spherical, clinker and cylindrical packed beds as well as in the area of waste heat recovery. Thanks to its precise control and high flexibility, it enables detailed analyses. The data obtained with its help form the basis for an improved calculation of heat transfer coefficients and a deeper understanding of thermal storage technologies.

The apparatus is equipped with electronic heaters that are capable of heating air to temperatures of up to 800 °C. A maximum mass flow rate of 0.25 kg/s can be achieved. The system has a flexible stream system consisting of two controllable hot streams. In addition, a third cold stream can be integrated to vary mixing ratios. This configuration enables precise control of a wide range of measuring points. The development and acquisition of the hot gas generator was realised with funding from the German Research Foundation (DFG).

The hot gas generator supports various research activities and offers the opportunity to analyse high-temperature processes under controlled conditions. Its potential uses range from fundamental studies to application-orientated projects in the field of energy and process engineering.
