Welcome to the Implementing Agreement IEA Combustion

The Implementing Agreement for Energy Conservation and Emissions Reduction in Combustion was organized under the auspices of the International Energy Agency (IEA). The agreement calls for studying the combustion of primary fossil fuels, which provide more than 90% of the energy needed in industrial countries. Responding to market and regulatory conditions, manufacturers have developed price-competitive engines, furnaces, and boilers that are clean and reliable. However, the thermal efficiencies of existing combustion units are not optimum.


Recent computer advances have made it possible to develop complex numerical models of combustion, and advances in lasers have allowed for new measurements of the combustion process. If combustion can be simulated numerically and measured precisely, then we can ultimately increase the technical and economic performance of our engines, furnaces, and boilers, while maintaining optimal efficiency.


Under the original agreement, eight countries participated: Canada, Germany, Italy, Japan, Norway, Sweden, the United Kingdom, and the United States. The United States was the Operating Agent for the program. The purpose was to provide the improved understanding necessary to develop new combustion equipment that not only runs more efficiently but also causes less pollution and is capable of using alternative fuels.
