Recently, HFOs (hydrofluoroolefins) are presented as a group of the fourth generation refrigerants with zero ODP (Ozone Depletion Potential) and a very low GWP (Global Warming Potential). This paper presents a study on eight different HFOs and their potential applications in ORC (Organic Rankine...

In order to identify approaches for integrated gasification combined cycle (IGCC) plant optimization it is necessary to analyse where and why the losses in the process occur. Therefore a structured exergy analysis of an IGCC with carbon capture was performed to identify losses on a plant,...

With the objective to measure coal conversion at realistic operation conditions the Pressurised High Temperature Entrained Flow Reactor (PiTER) is developed. The pyrolysis of Rhenish lignite is studied at temperatures up to 1600 °C and pressures up to 2.5 MPa. At longer residence time (above...

Non-stoichiometric burner operation in oxycoal processes has been proposed as a means to control flame temperature and heat exchange on admissible levels similar to air combustion when reducing the recirculation rate i.e. increasing the oxygen concentration in the oxidizer. Thus, the additional...
