PhD: Ash–Bed Interactions in Biomass-Fired Boilers

Danmarks Tekniske Universitet; Ørsted; On-site; DKK 335,000 - 402,000; Full time

Job summary

DTU Chemical Engineering in Lyngby, Denmark, offers a 3-year PhD project on biomass combustion, ash chemistry, and high-temperature processes. You will investigate bed material transformation, agglomeration, and defluidization in biomass-fired fluidized bed boilers.

The DTU-Ørsted collaboration aims to improve understanding of ash-bed interactions and to develop experimental and modelling tools for evaluating agglomeration risk, fuel management, and industrial boiler operation.

Qualifications

• Background in chemical engineering, energy engineering, materials science, chemistry, mechanical engineering, process engineering or related field.
• Experience with biomass combustion, ash chemistry, or high-temperature experiments is advantageous.
• Ability to work independently and collaboratively with academic and industrial partners.

Responsibilities

• Investigate alkali interactions with bed materials under high-temperature conditions
• Characterise bed material transformation, coating formation, and melting behaviour
• Develop and validate models of high-temperature alkali chemistry and ash-bed interactions
• Study agglomeration and defluidisation mechanisms and mitigation strategies
• Translate findings into recommendations for industrial fluidized bed boiler operation
• Publish research in peer-reviewed journals and present at international conferences

Skills
