A Postdoctoral position is available at the Department of Energy and Process Engineering. Further information about the department may be obtained from  


Biomass, including the biogenic fraction of wastes, is an important renewable energy source and important as a part of security of supply in Norway. Biomass to energy (BtE) and waste to energy (WtE) plants in Norway need to comply with stricter emission limits and/or adjust to tighter profit margins, and EU have implemented a further reduction of emission limits from medium (scale) combustion plants. NOx, particulate and CO emissions are special concerns, as well as the operational challenges following particle deposition on heat transfer surfaces. The majority of the operational BtE and WtE plants in Norway are grate fired plants, and even though different grate technologies have been developed, they suffer from both variations in fuel quality and changing operating conditions, resulting in non-optimum operating conditions. To address those issues, modelling using reactor networks is used to gain insight of the operational processes of fuel bed conversion and pollutant formation inside the grate fired furnace. The postdoctoral position is part of the Knowledge-Building Project for Industry, GrateCFD, funded by the Norwegian Research Council and industrial stakeholders.

About the position

The objective of the work is to develop a reactor network tool for numerical studies of the emission and combustion performance of grate fired furnaces using stochastic models. Special emphasis will be on development of a stochastic reactor model approach including multi-phase treatment of the thermal conversion of solid fuels, and where the fuel bed is divided into a network of stochastic reactors that are relatively coarse grained but can handle detailed chemical kinetics. The work furthermore involves studies of the complex coupling between fuel bed and freeboard as well as transient effects for optimum operation of grate fired BtE and WtE plants. Matching experimental data and plant measurement campaigns with results from network simulations will be an important part of the project. In this part, close collaboration with industrial partners within GrateCFD will be crucial.


Applicants for this position must have a PhD in chemical or mechanical engineering sciences with emphasis on combustion modelling. Motivation for fundamental scientific research of practical relevance is essential. Genuine interest in mathematical modelling and good knowledge of programming is a prerequisite, but direct experience with stochastic reactor modelling and chemical kinetic modelling is essential.   

Excellent English skills, spoken and written, are required. Applicants from non-English-speaking countries outside Europe must document English skills by an approved test. Approved tests are TOEFL, IELTS, Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE).  


Postdoctoral candidates are remunerated in code 1352, and are normally remunerated at gross from NOK 485,700 per annum before tax. There will be a 2% deduction to the Norwegian Public Service Pension Fund from gross wage.

The appointment of the Postdoctoral fellow will be made according to Norwegian guidelines for universities and university colleges and to the general regulations regarding university employees.  

The Postdoctoral fellowship is awarded for 2 years.
