Welcome to the Oel-Waerme-Institut

OWI provides research services investigating and developing concepts and new technologies for heat and power generation on a basis of fossil and renewable fuels. It aims at developing energy-efficient and environmentally friendly products which are marketable. At the same time, OWI cooperates closely with industrial partners and research institutes and sees itself as an mediator between fundamental and applied research. OWI is a non-profit organisation and an acknowledged institute affiliated to RWTH Aachen University.


Micro-emulsions in middle distillate -
Study on the development of preventive measures

12th March 2015 – Biocomponents such as Fatty Acid Methyl Ester (FAME) or hydrogenated vegetable oils (HVO), are added to middle distillates like diesel and heating oil in Germany in order to increase the range of fossil fuels and to reduce greenhouse-gas emissions. Biocomponents contribute to the aging process of fuels, especially at long storage times. This can, among other things, lead to water-in-fuel-emulsions. Furthermore, by adding bio components, alkali- and alkaline earth metals, as well as phosphorus, get into the fuels.  … More

IGCS Workshop on Biodiesel in India –
IIT Madras and OWI conduct a joint Research Project

5th March 2015 – A workshop on “Promise and Challenges of Biodiesel as Sustainable Fuel for Future Use” took place at the Indian Institute of Technology Madras (IIT Madras) in Chennai, India, from 19 to 21 February 2015. More than 30 Indian and some German participants from academia and industry showed great interest in the fundamental and applied lectures which addressed issues of evaporation, combustion and autoxidation of biodiesel or challenges in production, material compatibility and sustainability.

Optimizing the heating of industrial furnaces -
Flat flame burner for liquid fuels newly developed in a research project

26th November 2014 – The Zink KÖRNER GmbH and the OWI „Oel-Waerme“ Institute developed a concept for flat flame burners with power levels of 90 kW and 180 kW for the use of liquid fuels (middle distillates such as heating oil) within a joint research project. Flat flame burners for gaseous fuels are state of the art for the heating of industrial furnaces. Based on a series of experiments on a test bench, a burner quarl with new geometry was created, which stabilizes the twisted flames of both power levels flat and with complete burnout. … More

Heating oil has a decisive impact on storage stability of biofuel oil -
OWI examined interactions between petroleum-based heating oil and FAME

21st Oktober 2014 – The composition of petroleum-based domestic heating oil can have a decisive impact on the long-term storage stability of fuel blends such as biofuel oil (“heating oil EL A Bio”). The OWI Oel-Waerme-Institut was able to prove within a more than 24 months enduring long-time storage examination of ten base heating oils and two FAME-qualities (fatty acid methyl ester), that the FAME-admixture respectively FAME-quality is not the only decisive factor determining the stability of the fuels. As part of the investigations, which were funded by the Institut für Wärme und Oeltechnik (IWO) and supported by the mineral oil industry and additive manufacturers, partly unexpected interactions occurred.

Fuel cells produced in series –
Business network BiS-Net founded

24th September 2014 – Mass production of fuel cells in Germany is the goal of the newly founded cooperation network BiS-Net. In this network, which also includes the OWI Oel-Waerme-Institut as a research partner, ten small and medium-sized companies and research facilities work on the realization of portable and stationary applications for marketable and mass production suitable fuel cells. The market introduction of technical realizable systems is mostly hindered by high costs due to the applied materials and production engineering. … More
