A two-year postdoc position on reduction of ash deposition and corrosion in WtE (waste-to-energy) plants by sulfur recirculation is available at the CHEC Research Centre, DTU Chemical Engineering. The position is part of the EUDP project “Sulfur Recirculation for higher green power production and lower dioxin formation” in collaboration with Babcock & Wilcox Vølund A/S, Babcock & Wilcox Vølund AB, and Måbjerg Energy Center.

Waste-to-Energy (WtE) technology is currently the most competitive and mature technology for producing heat and electricity from municipal solid waste. The electrical efficiency in WtE plants is limited by the maximum achievable temperature in superheaters, which is constrained by the corrosion caused by superheater deposits. Sulfur Recirculation is a technology developed to reduce the corrosion rate of the superheaters in WtE plants, by recirculating sulfur from the wet flue gas cleaning back to the boiler in a form of sulfuric acid, and thereby producing a less corrosive environment for the superheaters by decreasing the Cl/S ratio in the deposits.

To support the further development of the Sulfur Recirculation technology, this project aims to provide a thorough evaluation of the effect of sulfur addition on ash deposition and corrosion under WtE boiler conditions.

Responsibilities and qualifications
The main responsibilities and tasks of the candidate include:

  • Performing full-scale ash deposition probe measurements in a WtE plant operating with Sulfur Recirculation technology
  • Conducting experiments in an entrained flow reactor to evaluate sulfur addition on ash chemistry and deposition under conditions relevant to WtE plants
  • Evaluating full-scale and laboratory experimental results using theoretical tools such as chemical kinetic modelling and thermodynamic equilibrium calculations
  • Writing technical reports and scientific articles
  • Application (cover letter)
  • CV
  • Academic Diplomas (MSc/PhD)
  • List of publications
  • All interested candidates irrespective of age, gender, disability, race, religion or ethnic background are encouraged to apply.

    The Department of Chemical and Biochemical Engineering at DTU is a leader in innovative teaching and research, built on core technical subjects and engineering scientific disciplines. The teaching and research covers separation processes, reaction engineering, dynamics and process regulation, process and facility planning, unit operations, heat transmission, fluid mechanics and applied thermodynamics. The Department enjoys very close relations with international partners, and especially a wide range of industrial companies.

    Technology for people
    DTU develops technology for people. With our international elite research and study programmes, we are helping to create a better world and to solve the global challenges formulated in the UN’s 17 Sustainable Development Goals. Hans Christian Ørsted founded DTU in 1829 with a clear vision to develop and create value using science and engineering to benefit society. That vision lives on today. DTU has 12,000 students and 6,000 employees. We work in an international atmosphere and have an inclusive, evolving, and informal working environment. Our main campus is in Kgs. Lyngby north of Copenhagen and we have campuses in Roskilde and Ballerup and in Sisimiut in Greenland.
