Technical Meeting Combustion Diagnostics, Control, Computational Methods & Process Optimisation

DATE:2nd May 2013
Venue:The University of Kent, Canterbury

The following meeting summary was kindly provided by Dr Gang Lu of the University of Kent.

The British Flame Research Committee (BFRC) in collaboration with the CRF and the University of Kent held a one day technical meeting on Combustion Diagnostics, Control, Computational Methods and Process Optimisation at the Darwin Conference Suite, the University of Kent at Canterbury on 2nd May 2013. The meeting aimed to provide a forum for combustion researchers, engineers and managers for exchange of up-to-date methods, developments and examples of use in continuous process monitoring and control and computational methods in combustion optimal diagnostics.

There were around 40 delegates from the UK, Italy, France and Germany who attended the event. Mr Roger Dudill, Chair of BFRC, opened the meeting. He welcomed all delegates to the meeting and then introduced Professor Leo Tognotti from the IFRF (International Flame Research Foundation) for the keynote presentation on combustion diagnostics and computational methods for process optimization. Professor Tognotti provided a deep insight into research capabilities and activities within the IFRF and described the IFRF’s large-scale energy research facilities. He further discussed the importance of the subject of his address in the continuing efforts to improve the quality of data acquisition to minimise the uncertainties inherent in experimental work.

There were 11 oral presentations broken down to three sessions which included laboratory-scale experience, CFD and computational analysis, and industrial-scale experience.

Dr Will Quick from E.ON chaired the first session which had three presentations. Mr Youssef Joumani from L'Air Liquide R&D presented the experimental estimation of separated jet oxy-flames in a 1,000C furnace. Mr Mohammed Hossian from the University of Kent gave a talk on the monitoring and characterisation of oxy-gas burner flames using digital imaging and spectral analysis techniques. Professor Mohamed Pourkashaniafrom the University of Leeds introduced the national research and development facilities for carbon capture and bio energy.

Professor Yong Yan from the University of Kent chaired the second session which comprised four presentations relating to computer modelling. During the session on computer modelling, Dr Angus Duncan from Doosan Power presented the validation of CFD modelling for conventional and unconventional combustion. A presentation of work carried out by personnel at the University of Stuttgart, RWTH Aachen University and the University of Rouen was made which described the experimental and computational investigation of flameless oxidation of pulverised coal at pilot scale (230kWth). Professor Gordon Andrews from the University of Leeds introduced the internal gas composition and CFD predictions of counter-rotating axial swirlers with axial fuel injection between the two swirlers. Dr X. Liu from the University of Sheffield talked on the heat transfer of zinc galvanization.

Professor Pourkashanian chaired session three which comprised four presentations relating to industrial applications. John Goldring from RJM International presented the results from a study on low NOx combustion at SSE Ferrybridge. Rex Isaacs from Zeeco Inc. introduced the low NOx burner retrofits with BMS for process heater optimisation. Mr Pallaniappan Valliappan from the University of Glamorgan talked about the monitoring and control of burners co-firing coal and biomass using joint time-frequency methods. Miss Gao from the University of Kent presented the in-line measurement of particle size distribution at a biomass-fired power plant.

There was also a Poster Session including six posters presented by Cardiff University, University of Leeds and University of Kent. Roger Dudill concluded the meeting, summarising how the meeting brought examples of all relevant development pipeline topics together to emphasise their inter-related benefits, and how these separate elements may work together to deliver emissions-compliant, fuel-flexible and efficient combustion systems that have predictable capabilities, whether the systems are modified and re-worked or ab initio designs. With the permission of the presenters it is the intention to make the all presentations and posters available on the BFRC website.
