Slowing down natural aging processes
6 July 2018 – Diesel fuel and heating oil, which chemically belong to the middle distillate group, are subject to natural ageing during storage. The addition of alternative and biogenic liquid fuels to mineral oil-based middle distillates can accelerate the aging processes. For example, fatty acid methyl esters from regenerative raw materials promote the increased formation of sediments and acids as well as oxidation. The causes of sedimentation have not yet been fully explained. If fuels produced from different fossil and alternative raw material sources are mixed, effects occur which have not yet been sufficiently investigated.
Doctorate at OWI
27 June 2018 – M.Sc. Winfried Koch successfully defended his dissertation at RWTH Aachen University in April 2018. His work deals with the influence of the thermal stability of liquid fuels and combustibles on the formation and degradation of residues in porous media evaporators. It was written at the OWI Oel-Waerme-Institut as part of the research project “Influence of evaporation behaviour on the coking tendency of liquid fuels on wetted surfaces”.
Sponsorship of the “Future Fuels Research Cluster”
5 June 2018 – AVIA AG has been supporting the research and development activities of OWI Oel-Waerme-Institut gGmbH in the field of future fuels since April 2018. AVIA and OWI have signed a sponsorship agreement to support the “OWI Research Cluster Future Fuels”. According to the current status, this comprises 13 individual projects for the years 2016 to 2020 with a total project volume of around 6.3 million euros.
Reliably determination of storage stability
23 May 2018 – Due to the greenhouse gas reduction and therefore an important role in the climate agreement, liquid fuels become increasingly important. Today fatty acid methyl ester (FAME) from used cooking oil (UCOME) can be already added as well as hydrogenated vegetable oil (HVO) can used as a fuel oil substitute. Other biogenic and synthetic fuels (XtL) are developed currently. Fuels consisting of several components have to be long-term stable and resistant to ageing while storage in the fuel oil tank. The quality of fuels has to correspond to the standard of fuels with alternative shares.
Doctorate at OWI
22. Mai 2018 – Dipl.-Ing. Hajo Hoffmann successfully defended his dissertation at RWTH Aachen University in February 2018. His work contributes to the investigation of internal deposits on diesel injectors (“A Contribution to the Investigation of Internal Diesel Injector Deposits”). It was written at the OWI Oel-Waerme-Institut as part of a research project („ENIAK“) to investigate the causes of injector malfunctions in diesel engines. In subsequent projects („ENIAK2“ and „SaveBio“), the interrelationships at OWI are further investigated. Hajo Hoffmann currently works at TEC4FUELS GmbH, the parent company of OWI, as head of the “Qualitywatch” business unit, which deals with the testing of fuels for emergency power systems.
Efficient and economical operation of industrial furnaces
2 May 2018 – e-flox GmbH, the Institute of Combustion and Power Plant Technology at the University of Stuttgart and the OWI Oel-Waerme Institute have jointly developed a new combustion concept for the use of different liquid and biogenic fuels in the FLOX® process. The FLOX® process involves flameless oxidation or combustion of the fuel, which gives the process its name. The developed prototype enables a low-emission and deposit-free conversion of liquid fuels through fine atomisation and the introduction of fuels adapted to the FLOX® process.
Substantial Greenhouse Gas Emission Savings and
Ash Recycling are Realisable
19 December 2017 – The Residue2Heat project reveals that substantial greenhouse gas emissions savings and ash recycling are possible by switching to fast pyrolysis bio oil for residential heating.
The goal of the EU research project “Residue2Heat” is to use various streams of biomass waste for residential heat generation. By means of the fast pyrolysis process, the biomass waste is converted into fast pyrolysis bio-oil, a 2nd generation biofuel suitable for combustion in an adjusted residential boiler.
