PhD Project - Optimal use of biomass in power plant boilers Combustion and Harmful Emission Control Research Centre Department of Chemical Engineering
A 3-year PhD position on the above mentioned topic is open at the CHEC (Combustion and Harmful Emission Control) Research Centre, Department of Chemical Engineering, Technical University of Denmark.
*Supervisors: *Associate Professor Peter Arendt Jensen (paj@kt.dtu.dk), Associate Professor Flemming Frandsen (ff@kt.dtu.dk), Professor Kim Dam-Johansen (kdj@kt.dtu.dk).
*Background:
*Utilization of biomass on large power plants is a potentially efficient method to reduce net CO2 emissions and reduce the consumption of fossil fuels. Use of biomass fuels in large suspension-fired boilers may cause operational problems. One example is when straw is applied as fuel in suspension fired boilers whereby severe ash deposit formation in the boiler chamber often takes place. Improved technologies for ash deposit removal are therefore needed.
This PhD study will deal with the development of models, experimental tools and innovative concepts to reduce ash related problems in biomass fired power plant boilers. The study shall be founded on solid knowledge on Chemical Engineering and will be conducted in tight collaboration with industrial partners. In some recent CHEC-projects both modeling tools, advanced probes and laboratory equipment have been developed and those tools will be available for the PhD project.
*Project content:
*The main objective is to develop methods to optimize the use of straw in power plant boilers and to develop and verify a model of the transient deposit formation in a boiler. Practical probe measurements on a full scale boiler will form the basis for a mathematical model for deposit formation taking all important parameters into consideration. Based on the results strategies for efficient boiler operation is to be established. The project will be conducted in collaboration with the power company Vattenfall.
The PhD-candidate will carry out the model development and conduct the probe measurements together with technicians. Vattenfall will operate the boiler and participate in the planning of the project.
*Contents of PhD application:
*Candidates should hold a master degree in chemical engineering, or similar degree with an equivalent academic level. Applications must include Curriculum Vitae, a statement on your motivation for applying, recommendations, and copies of all grade lists and other relevant diplomas.
