Fuel flexibility and emission control in connection with the production of electricity and heat in energy-intensive, industrial processes

The project is divided into the following four areas of interest, across different combustion technologies and fuels. 1) Pyrolysis of Solid Fuels - this activity is carried out partly in cooperation with Advanced Fuel Research, USA, where a research fellow will be stationed for a period of six months. A number of fuels are pyrolyzed in different types of reactors with the purpose of developing pyrolysis models. 2) Properties of the Char - methods for the evaluation of char reactivity are being developed. Chars from different fuels and reactors will be investigated with the focus on processes of importance for the char burnout. The emphasis will be on the formation of NOx from char combustion. 3) Combustion of Pyrolysis Products - as one of the results from Project 1, the composition of the pyrolysis gas obtained under different reaction conditions will be determined. On this basis, the combustion of model components will be investigated in laboratory scale flow reactors with the purpose of developing kinetic models for the combustion of pyrolysis gas and of selection for the formation of NO and N2 O under different conditions. 4) Experimental Facilities - different experimental facilities will be used in connection with the project. Some of these will have been built for earlier projects, some are available through the project partners and some facilities will be built as part of the project
