TUM offers four installations:
1. Entrained Flow Reactor: (EFR)
The Institute of Energy Systems provides with the electrically heated flow reactor a test facility with the capability of combustion experiments in a drop tube furnace. The external heating can reach temperatures up to 1600 °C at atmospheric pressure. The reactor consists of five sections, which offers the possibility to control the temperatures for each segment independently. The mass flux of the fuel can be adjusted from 0.5 to 2 kg/h. The fuel feeding system consists of two external hoppers. Thus, the share for co-firing can be adjusted over a wide range. The height of the vertical combustion tube is 2 m with a tube diameter of 150 mm.
2. Allothermal gasifier: (HPR)
The Heatpipe Reformer (HPR) at TUM is an allothermal gasifier designed as a bubbling fluidized bed using steam as gasification medium. The necessary heat for the gasification process is provided through an electrical heater and transported into the fluidized bed via alkalimetal-heatpipes. The heating system has a maximum power of 15 kW. The gasification temperature can go up to 850 °C. Moderate overpressures are possible, up to 4 bar. The reactor has a length of 1.5 m and the internal diameter is 154 mm. Any pelletized fuel can be fed into the reactor with a pressurized screw driver with a maximum fuel input of ~50 kW. For the investigation of tar
cracking catalysts two fixed bed reactors are coupled downstream the reactor in a slip stream.
3. Pressurized High Temperature Entrained Flow Reactor (PiTER)
The PiTER at TUM is a worldwide unique facility designed for operation conditions up to 1800°C, up to 50 bar and very flexible gas atmospheres. Worldwide there are a handful of facilities that enable the analysis of coal gasification in entrained flow conditions, but no system can reach even one of the operation limitations mentioned above. The worldwide strong efforts on coal gasification research, especially in the field of Integrated Gasification Combined Cycle (IGCC) technology, increase the demand for high-tech facilities like the PiTER at TUM.
4. High Temperature Entrained Flow Reactor (BabiTER)
The high temperature entrained flow reactor is designed for the investigation of gasification kinetics. Pulverized fuels can be fed in a range of 0.2-1 kg/h and gasified in a well defined gas atmosphere (N2, O2, H2, CO, CO2). The ceramic reaction tube can be heated up to 1600 °C.
