Optimiser la combustion pour un développement durable du bois-énergie

Abstract

Wood-energy, mainly used for private heating, industrial boilers and heating networks, includes high unexploited potentials as resources or consumers. In this perspective of development, the following work deals with the study of 18 wood fed boilers providing a power between 20 kW and 4 MW and several independent heating devices providing around 10 kW. As carbon monoxide is a very relevant indicator of the quality of combustion, we used this measurement to qualify the devices and to follow the influence of parameters such as the shape of the fireplace, the system of regulation or the quality of the fuel on the results of combustion. Indeed, the use of wood as a source of energy is considered as renewable and interesting for sustainable development only if the pollutant emissions are low and under control. Nowadays, all installations respect and pass the norms of restriction for pollutant emissions, but it is now necessary to carry on with improving in order to reach the same thermic and environmental performances as those using fossil fuels.
