Abstract :In the study, the combustion and fuel properties of slurry fuels, which are formed by mixing biomass as agricultural waste, sludge swage and algae, and coal as lignite and anthracite in certain proportions, were investigated. The energy properties of new slurry fuels were compared with fossil fuels such as lignite and anthracite, according to the Van Krevelen diagram used. The required stoichiometric air-fuel ratio insert ignore into journalissuearticles values(SAFR); amount in the burner was calculated during the combustion process. The real fuel-air ratio insert ignore into journalissuearticles values(RFAR); amount in the burner was determined during the combustion process according to the excess air coefficient insert ignore into journalissuearticles values(λ); value of 1.5.; as agricultural waste Rice Husks insert ignore into journalissuearticles values(RH);, Corn Cobs insert ignore into journalissuearticles values(CS);, Walnut Shells insert ignore into journalissuearticles values(WS);, Sunflower Shells insert ignore into journalissuearticles values(SS);, Olive Cake insert ignore into journalissuearticles values(OC);, Woodchips insert ignore into journalissuearticles values(WC); and as other biomass; Brown algae, sewage sludge have been used. As lignite, eight different types with low fuel properties and anthracite, which is the best coal fuel, were used. In the study, the H/C ratio was found to be 1.126 for the mixture of Anthracite + Sewage Sludge + Sunflower Shells insert ignore into journalissuearticles values(SS); depending on the sewage sludge for the slurry fuels mixture. If it is dependent on Algae, a value of 1.243 was calculated for the mixture of Muğla Ikizköy + Algae + Sunflower Shells insert ignore into journalissuearticles values(SS);. The O/C ratio was found to be 0.242 for Anthracite + Sewage Sludge + Olive Cake insert ignore into journalissuearticles values(OC); depending on the sewage sludge for the slurry fuels mixture. For Algae, a value of 0.129 was calculated for the mixture of Anthracite + Algae + Olive Cake insert ignore into journalissuearticles values(OC);.
