摘      要：One option to fight global warming is to convert our use of fossil energy into renewables such as biomass ***,the forest preservation and the quality of the ambient air are also two major ***,the use of biomass waste without any supplementary emissions could represent a part of the *** this study,two fuels were considered for a 200 kW moving grate boiler.A multicyclone and a bag filter were fitted on the *** first fuel consisted of classical wood chips whereas the second was a mixture of wood chips with sewage *** second fuel presented a high ashes mass ratio compared to wood *** aim was to verify the possibility to burn this kind of fuel without any modification of the *** first relevant result is that the conventional pollutants,i.e.,CO and NOx,remained under the emissions limits even with the sewage sludge *** Total Suspended Particles emissions at the exhaust were always under 5.4 mg·Nm-3 dry based corrected at 6%of O_(2),which is low with respect to the standard *** majority of the ashes remained on the combustion ***,with both fuels,about 5%of ashes mass remained in the heat ***,the heat exchanger was more clogged with the second fuel,which produced five time more *** may lead to a yield ***,sewage sludge can be used in a wood boiler without any issue if an automatic exchanger sweep is fitted on the installation.
