CECOST - Centre for Combustion Science and Technology

CECOST consists of a national Research Program, a Strategic Research Centre at Lund University and a national Graduate School. CECOST is hosted by the Faculty of Engineering LTH at Lund University in collaboration with Chalmers University of Technology, the Royal Institute of Technology and Växjö University.

The national research program is funded by the Swedish Energy Agency 2006-2009. The Strategic Research Centre at Lund University is funded by the Swedish Foundation for Strategic Research 2006-2010.

CECOST was founded in 1996 at the Faculty of Engineering LTH, Lund University in close collaboration with Chalmers University of Technology and the Royal Institute of Technology. The centre was funded by the Swedish Foundation for Strategic Research.

During the years 2002-2005 the Research Program was funded by the Swedish Energy Agency and the Graduate School by the Foundation for Strategic Research. Växjö University joined the CECOST activities in 2002.

Research programmes

SP Fire Technology participates in the CECOST national research programmes. The SP research activities are briefly given below. For detailed information on the individual projects:

 

Project: Flame Spread Project
Research programme: CECOST 1 (1999-2002)
Participants: LTH Fire Safety Engineering (project leader), SP Fire Technology, CTH Energy Conversion, LTH Heat Transfer, LTH Combustion Physics, Göteborg University Physical Chemistry
 
Sponsors: The Swedish Foundation for Strategic Research (SFF), Brandforsk, SRV, SBUF
 
Project description: Flame spread is an important concept in fire hazard analysis, as it governs the in many cases fast growth of a fire. The aim of the project was to improve CFD simulation of flame spread and fire growth. The project contained improvement of models for important physical sub-processes, as well as experimental work for validation purposes.
 
SP main activities:  The aim of the work was to design experiments and to provide experimental data for validation of different sub models and the total model in computer programs (CFD) for calculation of realistic flame spread scenarios. A series of large-scale flame-spread experiments with three different building materials was carried out [1]. Thermal properties for these materials, from room temperature to elevated temperatures, were determined using the TPS-method [2].

Project: Spontaneous ignition in stored biofuels and biological waste
Research programme: CECOST 2 (2002-2005)
Participants: LTH Fire Safety Engineering (project leader), SP Fire Technology, LTH Building Technology, Växjö University
 
Sponsors: The Swedish Energy Agency (STEM), Brandforsk, SRV
 
Project description: Spontaneous combustion of long-term storage is a long-standing practical problem that, in spite of extensive and intensive studies, has proved to be so intractable that there is still need for a definitive working model capable of prediction of ignition behaviour with accuracy. The main aim was to develop a prediction tool for the evaluation of waste material that needs to be stored in anticipation of material or energy recycling. This enables users to determine the correct method of storage to minimise the risk for self-ignition. The project contained model development [1], analysis of biological [2] and chemical activity in biofuel such as sawdust, wood chips and wood pellets, determination of thermal properties, and validation experiments of spontaneous ignition in sizes from 1 dm3 to 1 m3.
 
SP main activities: Chemical activity from small-scale experiments [3-5], thermal properties [4], and large-scale validation experiments [4-5].

Project: Biofuel Project - Spontaneous ignition
Research programme: CECOST 3 (2006-2009)
Participants: LTH Fire Safety Engineering (project leader), SP Fire Technology, LTH Building Technology, Växjö University
 
Sponsors: The Swedish Energy Agency (STEM), additional sponsors are welcomed (February 2007)
 
Project description: Continuation of the work initiated in the “Spontaneous ignition in stored biofuels and biological waste project” (see above). The aim will be on pelletized fuel, near production and new types of raw materials. Development and validation of the prediction tool, development of characterization methods, and validation experiments in different scales.
 
SP main activities: Study of pellet properties near production, use and assessment of prediction tool, and validation experiments [1-2].
