Job summary

DTU Chemical Engineering invites applications for a PhD project focusing on biomass combustion ash interactions, bed material transformation and defluidization in biomass-fired fluidized bed boilers, conducted in collaboration with Ørsted. The project combines laboratory-scale experiments, high-temperature gas-solid reactions, material characterization, thermodynamic modelling and chemical kinetics.

The PhD starts 1 December 2026 and runs for three years, with a strong industrial relevance and

Candidate has a background in chemical engineering, energy engineering, materials science, chemistry, mechanical engineering, process engineering or a related field.
Proficiency in English (written and spoken) is required.

Responsibilities

Investigate alkali interactions with bed materials at high temperatures.
Characterize bed material transformation, coating formation, and melting behaviour.
Develop and validate models of high-temperature alkali chemistry and ash–bed interactions.
Study agglomeration and defluidization mechanisms and mitigation strategies.
Translate scientific findings into recommendations for industrial fluidized bed boiler operation and fuel management.
Publish research in peer-reviewed journals and present at international conferences.
